Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does mRNA do?
A
carries information from genes to ribosomes
B
carries amino acids to ribosomes
C
helps with RNA splicing
D
make up ribosomes
Explanation: 

Detailed explanation-1: -mRNA is called as messenger RNA. It is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.

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 type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Detailed explanation-4: -mRNA carries genetic information from DNA to ribosomes. Ribosomes are the site for protein synthesis. The process of translation takes place in ribosomes.
