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

20,000-25,000

Explanation:

Adenine, thymine, guanine, and cytosine are the four nitrogenous bases that make up DNA.

Humans cant have three million genes, its just not possible.

there are 23 Pairs of Chromosomes

(chromosomes are the things that store genes)

So it has to be 20,000-25,000 genes

The correct answer is 20,000-25,000 genes.

Explanation:

The human genome was fully sequenced during the human genome project which was a 13 year-long project started in 1990 and completed in 2003. During the human genome project it was found that the human genome is made up of 3 billion base pair sequence of DNA.  

These 3 billion base pairs constitute to form 20 to 25 thousand genes present in the chromosomes in the nucleus.  Every cell contains all the genes but only specific genes are expressed in a particular cell according to their function in the tissue.

Therefore, the correct answer is 20,000-25,000 genes.

the answer is "a.) well–developed vascular system."

explanation:

the answer is c most of the fortnite players usually buy v bucks to get the battle pass and other cosmetics but some players who are referred to as "no skins" don't   buy skins and are usually noobs.
