Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A segment of DNA that codes for a particular protein ____ which in turn codes for a trait ____ is called a ____
A
mutation
B
nitrogen base
C
phosphate group
D
gene
Explanation: 

Detailed explanation-1: -Answer and Explanation: The segments of DNA that code for specific traits are called genes. Chromosomes are large structures made up of DNA and various organizing proteins.

Detailed explanation-2: -Gene. A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism.

Detailed explanation-3: -A (b) gene is a segment of the DNA molecule that carries the genetic code to make a protein. In order for a gene to generate a protein, it must first be transcribed into a piece of mRNA (messenger RNA). The mRNA will then be translated into a fully functional protein through the process of translation.
