During the process of translation in a eukaryote messenger RNA is spliced in the nucleus. amino acids are synthesized by RNA pol
svetlana [45]

Answer:

mRNA interacts with ribosomes in the cytoplasm.

Explanation:

<em>The correct option would be that mRNA interacts with ribosomes in the cytoplasm.</em>

Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.

<u>During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon</u>.

Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.
