Transcription is the process of copying a section of DNA into a complementary strand of mRNA. Translation is the decoding of an mRNA message into a polypeptide chain by a ribosome, starting at a START codon and stopping at a STOP codon. The document provides an overview of transcription and translation and encourages practicing replicating DNA, mRNA, tRNA, and protein sequences.

3. Transcription
• Process in which part of the nucleotide
sequence of DNA is copied into a
complementary strand of mRNA (messenger
RNA)

4. What is the difference between
RNA & DNA?

5. Translation
• Decoding a mRNA message into a polypeptide
chain
• (mRNA from the nucleus is turned into an
amino acid chain at the cell’s ribosomes)

6. Translation
• Translation does not begin until a START codon
is read by the ribosome (AUG)
• Translation is terminated when a STOP codon is
read by the ribosome (UAA, UAG, UGA)

7. Practice. Practice. Practice.
• For the following strand of DNA, provide the
complimentary DNA strand, mRNA strand, and
tRNA anticodons, and polypeptide chain.
