The DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones
D. Predators
Predators keep populations of other species in check. This was pretty clearly demonstrated in Yellowstone National Park after the wolves were eradicated there. The deer populations increased to the point that the aspen trees nearly disappeared due to the saplings' being eaten by deer. Since the reintroduction of wolves to the park, the aspen trees have begun to flourish once again.
<u>Primary structure of the protein </u>can be determined With the knowledge of the nucleotide sequence of a gene.
- Strings of amino acids make up proteins, and strings of nucleotides make up nucleic acids.
- A water molecule is removed during a biological process that links the carboxyl group of one amino acid to the amino group of a nearby amino acid to generate peptide bonds.
- The main structure of a protein is thought to be its linear amino acid sequence.
- A codon is a cluster of three mRNA nucleotides that codes for a particular amino acid.
- Each mRNA produces a protein that has a specific amino acid sequence corresponding to it. The start and stop of translation are indicated by two codons known as start and stop codons.

Answer:
They are used as an indicator organism for pathogenic bacteria.
Explanation:
Coliforms are bacteria found in digestive tract of animals and humans. They are non-pathogenic, easy to culture and are used as an alternative indirect testing for presence of other microorganisms. Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.
Therefore the existence of coliforms in water easily indicates feacal contamination.
