Question

The human genome contains more than ______ nucleotide pairs.

विकल्प

• 6 million

• 3 billion

• 4 million

• 5 billion

Answer 1

The human genome contains more than 3 billion nucleotide pairs.

Explanation:

The human haploid genome (the set of DNA found in a single reproductive cell) consists of approximately 3.2 billion base pairs. When the Human Genome Project completed its mapping, it confirmed that these billions of nucleotide pairs are organised into 23 pairs of chromosomes. This massive sequence contains the instructions for building and maintaining a human being, though only about 1.5% of these 3 billion pairs actually code for proteins.
