Question

transcription and translation
what is the purpose of mrna?
it attaches to the ribosomes.
it carries the code from dna to the area outside the nucleus.
it forms the anticodons.
it carries amino acids to the ribosomes.

Explanation:

mRNA (messenger RNA) is transcribed from DNA in the nucleus. Its main function is to carry the genetic code (information) from DNA (where it is stored in the nucleus) to the ribosomes in the cytoplasm (area outside the nucleus) where protein synthesis occurs.

• The first option “it attaches to the ribosomes” is not the main purpose. Ribosomes bind to mRNA, but the key is that mRNA is bringing the code.
• tRNA (transfer RNA) forms anticodons and carries amino - acids to the ribosomes, so the third and fourth options are incorrect.

Answer:

It carries the code from DNA to the area outside the nucleus.
