Question

Which of the following is true for most genes?

A. A gene is a segment of DNA that contains the instructions for making a particular protein.
B. A gene is a segment of DNA that contains the instructions for making a particular RNA.
C. A gene is a region of DNA that controls a discrete hereditary characteristic of an organism.

Answer 1

A gene is a segment of DNA that carries the code for making a specific polypeptide chain. Most genes contain the instructions for a single protein. Each gene specifies the sequences of amino acids, which are the building blocks of proteins.

Step-by-step explanation:

A gene is a segment of DNA that carries the code for making a specific polypeptide chain. It contains the instructions to encode a protein, and is a basic unit of heredity passed from parent to child. Each gene specifies the sequences of amino acids, which are the building blocks of proteins. Most genes contain the instructions for a single protein, and there may be many genes on a single chromosome.
