This type of RNA carries the protein building instructions from the
nucleus to the ribosomes.
This type of RNA reads the message, gathers the amino acids, and
transports them to the ribosome.
This type of RNA is found in the ribosomes.

a) DNA is double stranded; RNA is single stranded.
b) DNA contains deoxyribose and RNA contains ribose.
c) DNA contains thymine; RNA contains uracil.

The purpose of transcription is to copy one gene from the DNA molecule. These instructions will then be
sent to the ribosomes in the form of mRNA.
