Question

Which of the following statements about nucleotides and genes is correct?

A. A gene contains thousands of chromosomes.
B. A nucleotide contains many genes and chromosomes.
C. Nucleotides form strings of DNA that make up genes.
D. Nucleotides form strings of chromosomes that make up DNA.

Answer 1

Nucleotides form strings of DNA that make up genes.

Step-by-step explanation:

Nucleotides are the building blocks of nucleic acids, such as DNA and RNA. Genes are specific sequences of nucleotides that contain the instructions for making proteins or RNA molecules.

Each gene is made up of a specific sequence of nucleotides, which are strung together to form DNA or RNA. So, the correct statement is that nucleotides form strings of DNA that make up genes.

For example, the DNA sequence of a gene can be thought of as a string of nucleotides, with each nucleotide representing a specific base-pair combination (adenine, guanine, cytosine, or thymine).
