How is genomics related to genes and DNA?
Answer:
A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
Genomic DNA, or gDNA, is the chromosomal DNA of an organism, representing the bulk of its genetic material. ... In research, genomic DNA is useful tools in applications such as PCR, library construction, Southern blotting, hybridizations, SNP analysis, and molecular diagnostic assays.
Answer:
DNA
DNA is the molecule that is the hereditary material in all living cells.
Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes. It's skinny as a whip and smart as one too, containing all the information necessary to build a living organism. In a very real sense, DNA is information.
WHAT IS DNA MADE OF?
DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide.
Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base. The nitrogenous base is the part of the nucleotide that carries genetic information, so the words "nucleotide" and "base" are often used interchangeably. The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymine—often abbreviated as A, C, G, and T, the letters of the genetic alphabet.
How did people find out that DNA is the hereditary material?
DNA was largely ignored for decades after a German chemist, Friedrich Miescher, first isolated the white, slightly acidic substance from the nucleus of cells in 1869. No one knew what DNA's function was—in fact, some doubted that it had a function at all—so they pretty much left the stuff alone.
Very few people thought that DNA could be the hereditary material. Early studies of DNA suggested, erroneously, that the molecule was made up of the same sequence of four bases repeated over and over—ACGTACGTACGT… for example. No one could imagine how such a monotonously simple molecule could contain the information necessary to build a living organism.
But during the 1930s and 1940s, new experiments began to suggest that DNA might, in fact, be important. It turned out that different strains of bacteria can exchange DNA and that when they do certain traits, such as the ability to cause disease in humans, can be passed from one strain of bacteria to another. Scientists also learned that when a virus infects a cell it injects its DNA into the cell, which then produces many copies of the virus, suggesting that DNA contains instructions for building viruses. And they found that different species of organisms have different proportions of bases in their DNA—one species might have DNA that is 30 percent A, 20 percent C, 20 percent G, and 30 percent T, while another might have 20 percent A, 30 percent C, 30 percent G, and 20 percent T. People began to think that genetic information might be written in the differences between the DNA bases of different species.
What does DNA look like?
A DNA molecule is a double helix, a structure that looks much like a ladder twisted into a spiral. The sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next. DNA is often said to have a sugar and phosphate "backbone."
Each rung of the ladder is made of two nitrogenous bases linked together in the middle. The length of a DNA molecule is often measured in "base pairs," or bp—that is, the number of rungs in the ladder. Sometimes, this unit of measurement is shortened simply to "bases."The structure of DNA was worked out in 1953 by James D. Watson and Francis Crick, who worked together in the Cavendish laboratory in Cambridge, England. By the time they began their work in the early 1950s, it was clear that DNA is the hereditary material, and scientists were racing to find out more about the long-ignored molecule, picking apart the implications of each new detail. Everyone knew they couldn't really understand how DNA works until they understood how its nucleotide building blocks are put together.

How do human beings affect the carbon dioxide and oxygen cycle?
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels.
Answer:
By breathing.
Explanation:
Humans inhale oxygen, and when they need to release it, (exhale) that oxygen is no longer oxygen and is now carbon dioxide. Trees and plants are what helps oxygen to exist in our world even though we breathe it in and convert it to carbon dioxide. Hope this helps ^^

Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous chemical substances, other environmental effects, and age.
What are the factors that affect gene expression?The level of transcription is where the majority of control over gene expression is exerted, and this is mostly due to the fact that proteins bind to certain locations on DNA.
It is possible for environmental elements such as nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens to have an effect on which of an animal's genes are expressed, which in turn has an effect on the animal's phenotype.

now you’ll examine an operon that undergoes negative and positive control. the ara operon in e. coli codes for enzymes that metabolize the sugar arabinose, which e. coli can use for energy. as you can see in the diagram, the regulatory protein arac can act as both an activator and a repressor of the ara operon.
The lac operon is known to be able to undergoes negative and positive control.
The diagram based on the 4 table arrangement is filled up below (Right to left);
In the presence of arabinose: initiator, activator, yes, yes.In the absence of arabinose: initiator and operator, repressor, no, no.
If a mutation prevents arabinose from biding to AraC: initiator and operator, repressor, no, no.
If arabinose is present but a mutation and AraD enzyme renders it non-functional: initiator, activator, yes, no.
The metabolism of the sugar arabinose is known to be influenced by an operon that is said to undergo both positive control and negative control.
Transcription of the ara operon is lead by the regulatory protein AraC, which then bound to the DNA.
When arabinose is present, it binds to AraC, and both parts of the AraC dimer are then also bound to the initiator, making transcription to move foreword.
When arabinose is absent, one part of the AraC dimer is often bounded to the initiator, while the other part is bounded to the operator, thereby hindering transcription.

The Sun and Moon, but the Sun impacts Earth's tides more because it is closer in distance to the Earth.
The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.
The Sun and Moon, but the Sun impacts Earth's tides more because it much more massive than the Earth.
The Moon is the only celestial object that influences Earth's ocean tides because it so close in distance to the Earth.
The answer option that most accurately describes what affects Earth's ocean tides is: B. The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.
A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the combined effects of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
Hence, an ocean tide describes the episodic changes in the height of the surface of an ocean as a result of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
In conclusion, the Earth's ocean tides is largely affected by the gravitational force of attraction exerted by the Moon than that of the Sun because the Moon is closer in distance to the Earth (approximately 400,000 kilometers).

Explain the relationships between dehydration synthesis, hydrolysis, monomer, and polymer
Answer:
combine with each other using covalent bonds
Explanation:
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
Answer:
Dehydration synthesis is a process by which two monomers are linked to form a polymer, with water being given off as a byproduct. Conversely, hydrolysis is the process by which water is introduced in order to break down a polymer into its monomer building blocks.
