Please helppp!

Why do cells need both tRNA and mRNA?

Answers-

Only mRNA can be used to repair mistakes in the DNA sequence.

Only tRNA bends into a shape that can carry specific amino acids.

The tRNA in used on the ribosomes and the mRNA is used in the nucleus.

The mRNA brings information to the nucleus for the tRNA to use.

Answer 1

DNA and RNA (m and t) are made of nucleotides. Proteins like hemoglobin are composed of amino acids.

The mRNA specifies the sequence information needed for making the hemoglobin protein. This information is a direct and temporary copy of information contained on a gene on DNA.

The tRNA is a separate molecule the carries an amino acid on it. It is like a mediator. It has sequence that matches to a small part of the sequence being specified by the mRNA. When the tRNA moves into the right position on the mRNA, the amino acid detaches from the tRNA and is added to the growing protein or polypeptide chain.

Answer 2

with this information i have provided you should be able to choose which one is correct

Answer 3

So D? That's the only one that makes sense from my lesson

Answer 5

So B? I'm sooo confused :/

Answer 6

yes
