The correct answer is the type and sequence of molecules along each strand.
The DNA is formed of molecules known as nucleotides. Each nucleotide comprises a sugar group, a phosphate group, and a nitrogenous base. The four kinds of nitrogen bases are thymine (T), adenine (A), cytosine (C), and uracil (U). The order of these bases is what that determines the genetic code or the DNA instructions.
Answer:
Option B. A double-stranded molecule with coded instructions for anorganism's physical characteristics, is the correct statement.
Explanation:
DNA is a genetic material which contains information about the physical features and characteristics of an organism. It is composed of five carbon sugar, phosphate group and nitrogenous base. The DNA base are adenine, cytosine, guanine, and thymine.
Answer:
Pleiotropy
Explanation:
Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism
- <em>gene pleiotropy</em>
- <em>developmental pleiotropy</em>
- <em>selectional pleiotropy</em>
- <em>antagonistic pleiotropy </em>
<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
Answer: Adaptation
species adapt to their environment
