1.
Construct an Explanation Based only on the information provided, why could the mRNA section be translated into three different sets of amino acids, instead of just one set?
2.
Use Models Use the genetic code to translate the sequence into each of the three possible sets of amino acids.
3.
Draw Conclusions Which of the three sets of amino acids is the most likely to be included in the polypeptide? Explain your reasoning.
Answer:
TAA ATT GAC AAG ACA GAT CTC
1. The more bases there are per codon the more information you can code for. There are only 22 different amino acids, in consequence we need minimum 3 bases per codon.
2. codon
three nucleotides—called a triplet or codon—codes for one particular amino acid in the protein. The nucleotide sequence in the DNA is first transcribed into a molecule of messenger RNA (ribonucleic acid).
3. Known as alpha helices and beta sheets, these stable folding patterns make up the secondary structure of a protein. Most proteins contain multiple helices and sheets, in addition to other less common patterns (Figure 2). The ensemble of formations and folds in a single linear chain of amino acids — sometimes called a polypeptide — constitutes the tertiary structure of a protein. Finally, the quaternary structure of a protein refers to those macromolecules with multiple polypeptide chains or subunits.
OKAY I THINK EVERYTHING IS RIGHT BUT SORRY IF WRONG ;)
3. It is not possible to determine which of the three sets of amino acids is the most likely to be included in the polypeptide based solely on the information provided.
What is a nucleotide sequence?A nucleotide sequence is the order of nucleotides (the building blocks of nucleic acids) in a DNA or RNA molecule.
Nucleotides are composed of a sugar, a phosphate group, and a nitrogenous base, which can be adenine (A), cytosine (C), guanine (G), thymine (T) (in DNA) or uracil (U) (in RNA). The specific order of these nucleotides in a DNA or RNA molecule determines the genetic information that the molecule carries.

Fossils usually occur in metamorphic rock. true or false?
Answer:
false
Explanation:
They can't survive the great pressures metamorphic rocks go through. They usually are only in sedimentary rocks. Hope this helps!
Answer:
false
Explanation:
Fossils are very fragile and metamorphic rocks go through some harsh changes, so i'd be impossible for fossils to stay intact or even form in metamorphic rocks
A primary air pollutant is put directly into air by human activity.What is a secondary air pollutant
Answer:
Acid Rain
Explanation:
Acid rain, which is made up of several acidic compounds, forms when sulfur dioxide and nitrogen dioxide react in the air with water, oxygen and other chemicals. On the ground, acid rain damages plants and trees and increases the acidity levels of soils and bodies of water, causing damage to ecosystems. Acid rain also causes decay to buildings and can irritate the eyes and airways.

What the Viceroy's color pattern evolved?The Viceroy's color pattern has been evolved because the natural selection favoured them. The viceroy butterfly camouflage as the monarch butterfly as well as the exhibit Mullerian mimicry where as these two toxic species has the mimic each other for their benefit and by time natural selection has been favoured these.
Natural selection has been the process by which the reproductively fitest has the populations of the living organisms survive, adapt and change. The viceroy butterfly has the brush-footed butterfly having the dark orange colour with the black veins and row of the white spots on the border of its wings.
Monarch butterfly has the same as that of the viceroy except that it has the black horizontal stripes that has cross the bottom of its back wings. Species has refers to the group of the organisms which have the similar features and which are able to be interbreed to produce the viable and the fertile offspring.
Therefore, reproductive isolation prevents interbreeding between members of different species. It includes a collection of behavioral, evolutionary, and physiological processes.

what’s the chemical reaction for the digestion of fats.
Answer: The chemical reaction for the digestion of fats is when A triester is produced through the chemical reaction of three fatty acid molecules with glycerol, a molecule that contains three hydroxyl groups. When fats are broken down these fatty acid chains and glycerol are free for the body to use.
Explanation:
Lipids (fats and oils)
Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Bile is not an enzyme.

Is glucose more or less complex than the rest of the biomolecules? Explain.
Answer:
Less complex.
Explanation:
Glucose is both a monomer and simple sugar.
Glucose is a monosaccharide. It is a biomolecule. It is less complex than the rest of the biomolecules, such as proteins, lipids, and other complex carbohydrates like glycogen.
What is a biomolecule?
Biomolecules are present inside the cell. Carbohydrates, proteins, and lipids are some examples of biomolecules. Carbohydrates are divided into monosaccharides, disaccharides, and polysaccharides.
A monosaccharide has a single unit. Examples are glucose, fructose, etc. A disaccharide consists of two units. An example is maltose. Maltose is made up of two units of glucose connected by a glycosidic bond. An example of a polysaccharide is glycogen. Multiple sugar units are connected by glycosidic bonds to form glycogen. It is a storage product.
Carbohydrates are present on our cell surface as peptidoglycan. Protein is a biomolecule that is made up of amino acid monomers. They make the different structures of a cell, such as actin fibers, etc. Lipid is made up of hydrogen and carbon. Examples are cholesterol, phospholipids, etc.
Hence, in comparison to all other biomolecules, glucose is the simplest.
