Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

In order for DNA instructions to move from the nucleus to the ribosomes in the cytoplasm of a cell, an RNA copy of a DNA strand must be made. This process, which takes place in a cell’s nucleus is called ____

A	translation
B	mutation
C	DNA replication
D	transcription

Explanation:

Detailed explanation-1: -In biology, the process by which a cell makes an RNA copy of a piece of DNA. This RNA copy, called messenger RNA (mRNA), carries the genetic information needed to make proteins in a cell. It carries the information from the DNA in the nucleus of the cell to the cytoplasm, where proteins are made.

Detailed explanation-2: -The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.

Detailed explanation-3: -The majority of genes carried in a cell’s DNA specify the amino acid sequence of proteins; the RNA molecules that are copied from these genes (which ultimately direct the synthesis of proteins) are called messenger RNA (mRNA) molecules.
