Question

A sequence of DNA nucleotides coding for a specific protein or RNA molecule is a:

Select one:
a. Gene
b. Genome
c. Chromosome
d. All of the above are correct
e. None of the above are correct

Answer 1

A sequence of DNA nucleotides coding for a specific protein or RNA molecule is known as a a) gene, which is part of chromosomes and contributes to the entire genome.

Step-by-step explanation:

A sequence of DNA nucleotides coding for a specific protein or RNA molecule is known as a gene. A gene is a segment of DNA that not only stores genetic information but acts as a set of instructions to make molecules called proteins. The entire genetic code is contained within the sequence of nucleotides in DNA, which is transcribed into mRNA and then translated into the amino acid sequence that makes up a protein.

The genome is the entire set of genetic material of an organism, consisting of multiple genes. A chromosome is the structure that DNA and proteins form to make up the genetic material in a cell. Therefore, while a gene is a sequence within the DNA that is responsible for the production of a specific protein or RNA molecule, it is part of the larger structures known as chromosomes, and collectively, all of the genes make up the genome.

In summary, the correct answer to the question is a. Gene.
