Question

Which statement is the best physical description of a gene?

A. A chromosome is a segment of a gene.
B. Genes carry many chromosomes.
C. A gene is a specific segment of DNA on a chromosome.
D. A gene consists of all of the DNA on a chromosome.

Answer 1

A gene is a specific segment of DNA on a chromosome that carries the code for making a specific polypeptide chain, which is a component of a protein.

Step-by-step explanation:

Best Physical Description of a Gene

The best physical description of a gene is that a gene is a specific segment of DNA on a chromosome. More precisely, a gene is a section of DNA that carries the code for making a specific polypeptide chain, which is part of a protein. Chromosomes are larger structures within cells, composed of DNA and proteins, and serve as carriers for the genetic material. Genes are the fundamental units within the chromosomes that contain the necessary instructions for making proteins. Each gene is responsible for the production of a particular protein or a part of a protein, and there may be many genes located on a single chromosome.
