Answer 1

mRNA is messenger RNA. It is used in each cell, not between cells.

The DNA always stays in the nucleus of the cell. Genes and other small segments of the DNA are copied in the nucleus, making mRNA. The mRNA travels out of the nucleus into the cytoplasm of the cell, where it is altered (if needed). Then ribosomes use it as a blueprint to chain together amino acids, which eventually become proteins.
