Multiple Choice Question

What is the minimal number of genes needed for a cell to function?

The correct answer would be - 200 to 300 protein-producing genes.

Explanation:

According to the studies, there are many genes that do not produce proteins and have no direct role in cellular functioning. According to the human genome project, there are 20000 to 25000 genes present in a human cell.

According to the study and researches, the minimum number of genes a single-celled organism needs to divide or reproduce itself and survive in the laboratory is approximately between 265 and 350.

Thus, the correct answer is - 200 to 300 protein-producing genes.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.
