A portion of the DNA molecule containing a sequence of base pairs that encodes a particular protein is known as a:​

Quizplus · Accepted Answer

A gene is a specific sequence of DNA that provides the instructions for making a particular protein. Each gene consists of a sequence of nucleotides that code for the amino acid sequence of a protein. Therefore, option A is the best choice. Option B, allele refers to a variant form of a gene that occurs at a specific location on a chromosome. Option C, double helix, describes the twisted ladder structure of the DNA molecule; it does not relate to a specific sequence that encodes a particular protein. Option D, chromosome, is an organized structure of DNA and protein found in cells. It contains many genes, among other things, but it does not refer to a specific sequence that encodes a particular protein.
