RNA
3 Types:
1. Messenger RNA (mRNA)
Carries a copy of the protein building
instructions from the nucleus (DNA)
to the cytoplasm
RNA
3 Types:
2. Ribosomal RNA (rRNA)
Assembles amino acids into proteins
RNA
3 Types:
3. Transfer RNA (tRNA)
Transfers amino acids from the cytoplasm to the
ribosome
Proteins
Monomers: Amino acids (20)
Order of the
amino acids
determines
protein function

1. Transcription
Building Blocks =
Amino Acids
2. Translation
Protein
1. Transciption
Copying DNA code to mRNA
Location: Nucleus
RNA Polymerase
copies one strand
of DNA to the
mRNA
Codons
Three consecutive nucleotides that
code for a specific amino acid
Start codon
Stop codon: UAA
UAG
UGA
Codons are like words that make up sentence
(amino acid sequence).
2. Translation
Decoding mRNA (codons) into an
amino acid sequence (protein)
Location: Cytoplasm
Translation
4. Ribosome forms bonds
between amino acids
3. tRNA brings a
specific amino acid
5. tRNA will be
released
6. Ribosome will
2. Complementary
continue until it
tRNA reads codon
reaches a stop codon
1. mRNA finds
a ribosome
