A ____ is a segment of DNA that codes for a particular protein, which leads to a particular trait.
A
Gene
B
Allele
C
Codon
D
Nucleotide
Explanation: 

Detailed explanation-1: -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-2: -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. They contain DNA for many genes so that is not the correct answer.

Detailed explanation-3: -Answer and Explanation: Segments of DNA that contain the genetic code for a particular trait are called genes. These genes come together to form the genome of an organism.

Detailed explanation-4: -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.
