These segments of DNA that contain the code for specific proteins are called genes.
Actual coding region of DNA are called exons.
Explanation:
A segment of DNA that codes for one distinct protein is called a gene. Each chromosome carries thousands of various genes. The genetic code of the DNA ever prevails protected inside the nucleus.
a gene is a stretch of DNA. Nucleotide consists of a sugar, phosphate and a base.. Genes are organized and packaged in units named “chromosomes.” Humans have 23 pairs of chromosomes.
