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

Which kind of RNA is a messenger that carries the instructions from the DNA to the ribosomes?

A	mRNA
B	rRNA
C	tRNA

Explanation:

Detailed explanation-1: -messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).

Detailed explanation-2: -mRNA, rRNA, and tRNA are the three main types of RNA involved in protein synthesis. RNA also serves as the primary genetic material for viruses. Other functions include RNA editing, gene regulation, and RNA interference.

Detailed explanation-3: -The type of RNA that carries instructions from DNA in the nucleus to the ribosome in the cytoplasm is mRNA. mRNA stands for messenger RNA and carries a copy of the gene on DNA to the cytoplasm so it can be translated into a functional protein.

Detailed explanation-4: -Messenger RNA (mRNA) carries the genetic code from DNA in a form that can be recognized to make proteins. The coding sequence of the mRNA determines the amino acid sequence in the protein produced.
