Question

What is the function of rRna?

Answer 1

Answer:

The function of mRNA is to carry the genetic information from the DNA to the ribosomes (option B).

Explanation:

mRNA is a nucleic acid molecule synthesized in the cell nucleus from information transcribed from DNA.

Each mRNA molecule contains a specific sequence of nitrogenous bases according to the sequence in the DNA that, organized in codons, indicates:  

• Amino acid to be incorporated into the protein molecule.
• The order in which the amino acids are attached to the molecule during synthesis.
• The start and stop of protein synthesis.

To fulfill its function mRNA must be coupled to the ribosomes, which translate the information and initiate the synthesis of protein molecules. For these reasons the main function of mRNA is  to carry the genetic information from the DNA to the ribosomes.

The other options are not correct because:

    A. mRNA does not send information to the cytoplasm, but transports it.

    C. It does not carry amino acids, as this function is of the transfer RNA.

    D. mRNA is not paired with the uracil, but contains it in its structure, as a nitrogenous base

    E. It is the function of DNA to direct the body to produce proteins.
