Question

Non-coding genes in human genome are called junk genes.

• A. True
• B. False

Answer 1

The correct option is A

True

The sum of genetic material present in an organism is called its genome. The human genome contains about 30,000 genes present in 46 chromosomes. Only about 2% of the genes code for proteins. Remaining 98% of the DNA contains many genes that are non-coding and are known as junk DNA. Non-functional genes do not code for any proteins.
