DNA AND PROTEIN SYNTHESIS
RNA (RIBONUCLEIC ACID)
-Another Nucleic acid involved in the synthesis of

RNA STRUCTURE
Differs from DNA in three ways:

are made in
the cytoplasm. mRNA serves as a “messenger” and
carries the protein building instructions to the ribosomes
in the cytoplasm.

PROTEINS
Structural and functional components of organisms.
Composed of
One gene codes for
protein
GENETIC CODE
The “language” that translates the sequence of nitrogen
bases in mRNA into the amino acids of a protein.
 1 Codon = 3 nucleotides on mRNA
 1 Codon =
 Some codons are redundant (can be used again to
give the same amino acid)
RESULT OF TRANSLATION
A Protein!!!!!
