Detailed explanation-1: -The correct answer is (a) genes are segments of DNA that code for proteins. The DNA strands that make up the double helix consist of a sequence. These sequences contain genes with the codes for producing specific proteins.
Detailed explanation-2: -Gene is a specific fragment or sequence of nucleotides in DNA which codes for a specific protein and controls its expression.
Detailed explanation-3: -Which of the following statements best describes the promoter of a protein-coding gene? The promoter is the non transcribed region of the gene.
Detailed explanation-4: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
Detailed explanation-5: -The coding region of a gene, also known as the coding sequence (CDS), is the portion of a gene’s DNA or RNA that codes for protein.
