In a eukaryotic cell, the DNA is enclosed in the nucleus, whereas the ribosomes that make proteins are located in the cytoplasm. How does the information in DNA that specifies the amino acid sequence of a particular protein get to the cytoplasmic protein-manufacturing centers?

The genetic information in DNA is carried to the cytoplasmic protein-manufacturing centers in form of mRNA.

Explanation:

The process of transcription forms RNA using the DNA template strand thereby copying the genetic information of DNA into the nucleotide sequence of mRNA.

The mRNA leaves the nucleus and enters the cytoplasm to join ribosomes. The nucleotide sequence of mRNA is read in the form of triplet codons to specify the amino acid sequence of the proteins.

In this way, mRNA serves as a carrier of the genetic information in DNA.
