DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A scientist needs to create an exact copy of a cell’s DNA. What process is required?
A
differentiation
B
DNA replication
C
mutation
D
protein synthesis
Explanation: 

Detailed explanation-1: -Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

Detailed explanation-2: -Definition. DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.

Detailed explanation-3: -Cloning is a technique scientists use to make exact genetic copies of living things. Genes, cells, tissues, and even whole animals can all be cloned. Some clones already exist in nature. Single-celled organisms like bacteria make exact copies of themselves each time they reproduce.

Detailed explanation-4: -Answer and Explanation: The process by which the DNA in a cell makes an exact copy of itself is known as DNA replication.
