Explanation:

What is a DNA fingerprint?

DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.

Background

Almost every cell? in our body contains our DNA?.  

On average, about 99.9 per cent of the DNA between two humans is the same.  

The remaining percentage is what makes us unique (unless you are an identical twin!).  

Although this might sound like a small amount, it means that there are around three million base pairs? that are different between two people. These differences can be compared and used to help distinguish you from someone else.  

Minisatellites are short sequences (10-60 base pairs long) of repetitive DNA that show greater variation? from one person to the next than other parts of the genome?. This variation is exhibited in the number of repeated units or ‘stutters’ in the minisatellite sequence.

The first minisatellite was discovered in 1980.  

DNA fingerprinting

DNA fingerprinting was invented in 1984 by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites.  

DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual. This is a DNA fingerprint.

The probability of having two people with the same DNA fingerprint that are not identical twins is very small.  

Just like your actual fingerprint, your DNA fingerprint is something you are born with, it is unique to you.

How was the first DNA fingerprint produced?

The first step of DNA fingerprinting was to extract DNA from a sample of human material, usually blood.

Molecular ‘scissors’, called restriction enzymes?, were used to cut the DNA. This resulted in thousands of pieces of DNA with a variety of different lengths.

These pieces of DNA were then separated according to size by a process called gel electrophoresis?:

The DNA was loaded into wells at one end of a porous gel, which acted a bit like a sieve.  

An electric current was applied which pulled the negatively-charged DNA through the gel.

The shorter pieces of DNA moved through the gel easiest and therefore fastest. It is more difficult for the longer pieces of DNA to move through the gel so they travelled slower.

Comets, Asteroids and metoeorites support the hypothesis that earth and the rest of the solar system was formed by a condensing nebula.

What are the functions of asteroids?

An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.

They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron).

Almost all of the asteroids in our solar system are orbiting in a broad band 19,400,000 miles wide between Jupiter and Mars. The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade.

termination of transcription in bacteria occurs when ________.

Answers

RNA polymerase

Termination of transcription in bacteria occurs when the RNA polymerase encounters specific DNA sequences that lead to stalling of the polymerase. This results in release of RNA polymerase from the DNA template strand, freeing the RNA transcript.

Transcription is the process of synthesizing the RNA transcript from DNA.

The termination of transcription in bacteria occurs when RNA polymerase comes in contact with some particular terminator sequences that stalls the RNA polymerase letting it fall off.

In transcription, there is its initiation (start) and its termination (and end). Unlike humans with stop codons that terminates the process, the bacteria uses a terminator sequence which it transcribes and cause its fall off the DNA and releasing the RNA transcript.

Answers

The most likely change in air quality is a decrease in carbon dioxide (CO2) present in the box.

Photosynthesis is the process by which green plants produce their own food in the presence of light and carbon dioxide. The most important indicator of air quality is carbon dioxide. This gas is removed during photosynthesis.

This implies that after two days, analysis of the air samples from the pot will definitely indicate a large decrease in the amount of carbon dioxide present in the box.

What are the four most common elements in all living things

Answers

Answer:

Oxygen

Oxygen is the most abundant element contained within living organisms, composing about 65% of the human body. Oxygen is also the most abundant element in the Earth's crust, and in the air that is essential for most life on Earth. Oxygen's presence in the body is largely in the form of water, which is used to produce the energy within the body needed to sustain life.

Carbon

Carbon forms the basis for all life on Earth; indeed, life forms on Earth are referred to as carbon-based life forms, emphasizing the importance of this element for life. Carbon atoms readily bond to other atomic elements, such as oxygen and nitrogen. Since carbon can so readily bond to other elements, long chains of bonds can form and provide the physical and chemical structure needed for the complex processes and structures that occur within living organisms, such as structural proteins and genetic information in the form of nucleic acids.

Hydrogen

Hydrogen is the simplest element, as its atom contains only a single proton and a single neutron. As a result of this simplicity, hydrogen readily bonds with other elements, making it an important component for the formation of living organisms. Hydrogen is the other element (along with oxygen) which forms water, a crucial component for most life forms on Earth. Hydrogen is also a byproduct in many biological reactions, including photosynthesis and metabolism.

Nitrogen

Nitrogen is one of the most abundant elements on Earth, composing approximately 80% of the air on Earth. Nitrogen is an important element in the development of plant life, as compounds containing these elements are readily absorbed and used by plants. Nitrogen is also an important component of many proteins and deoxyribonucleic acids (DNA), which is crucial for genetic material to be passed on to subsequent generations of life.

Sulfur

Sulfur is a major component of two essential amino acids used by living organisms: cysteine and methionine. These amino acids, like all amino acids, are crucial for the construction of proteins that are used for structural stability and repair of living organisms. For example, the structural integrity of hair and feathers can be attributed to these amino acids. Sulfur is also used as a source of energy and is metabolized by some species of bacteria and other lower life forms.

Phosphorus

Phosphorus is used in the formation of phospholipids, a type of molecule that is a major component of the cell membrane of all living cells. Without this cell membrane, cells would not be able to develop and would not have the structural stability to form in the first place. This protective layer of phospholipids holds all the internal components of cells in place, allowing for the processes that maintain the life of the cell to take place. The phospholipid layer also protects the cell by keeping any unwanted or potentially destructive materials outside of the cell.

Reinforcement and support

parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).

Answers

Explanation:

A skeletal muscle generates the greatest tension when it is: partially stretched before being stimulated

Skeletal Muscle generates the greatest tension when the muscle is stretched to an intermediate length, by length-tension relationship.

How tension generates in skeletal muscle?

Muscle tension is highest in skeletal muscles when stretched to an intermediate length, as indicated by the length-tension relationship.

When skeletal muscle fiber contracts, myosin heads link to actin to create cross-bridges, and the thin filaments slide across the thick filaments as the heads pull the actin, resulting in sarcomere shortening and muscular contraction stress.

The amount of stress produced by a muscular contraction is determined by two factors: the number of active muscle fibers and the frequency of neural stimulation of the muscle fibers.

Therefore greatest tension generates in skeletal muscle when it is stretched to the intermediate length.
