Question

How many genes make up the human genome?
four: adenine, thymine, guanine, and cytosine
23 pairs of genes
20,000–25,000 genes
3 billion genes

Answer 1

Answer:

The correct answer is - 20000, 25,000 genes.

Explanation:

Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.

According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.

Thus, the correct answer is - 20000, 25,000 genes.

Answer 2

Genes are the hereditary units, which are present in the coded segments of the DNA. Genes carry the information from parent to daughter cells.

There are 20,000 to 25,000 genes that make up the human genome.

Human Genome Project was conducted for several years, the result obtained was:

• The human genome project was an international scientific project, which aimed at determining the base pairs that make up the human DNA.

• The project estimated that humans consist of 20,000 to 25,000 genes in their genome. Each individual inherits the copies of genes from both parents.

Therefore, the correct answer is Option C.
