Question

Nucleotide pairs present in human genes vary between

• A. 100 - 1000
• B. 500 - 5000
• C. 2000 - 2,000,000
• D. 10,000 - 10,000,000

Answer 1

The correct option is C 2000 - 2,000,000

The human genome consists of 50,000 to 100,000 genes located on 23 pairs of chromosomes. One chromosome in each pair is inherited from the mother, the other from the father. Each chromosome contains a long molecule of DNA, the chemical of which genes are made. Genes are of differing length, ranging in size from roughly 2,000 to as many as 2,000,000 base pairs.

So, the correct answer is '2000-2,000,000.'
