Protien Synthesis

Question 1

Transcription PART 1

Answer 1

1. The double helix DNA unwinds
2. The double-stranded DNA unzips / weak hydrogen bonds break
3. To form two separate strands
4. One strand is used as a template
5. To form mRNA

Question 2

Transcription PART 2

Answer 2

6. Using free RNA nucleotides from the nucleoplasm
7. The mRNA is complementary to the DNA
8. mRNA now has the coded message for protein synthesis
9. mRNA moves from the nucleus to the cytoplasm and attaches to
   the ribosome

Question 3

Translation PART 1

Answer 3

1. Each tRNA carries a specific amino acid
2. When the anticodon on the tRNA
3. Matches the codon on the mRNA

Question 4

Translation PART 2

Answer 4

4. Then tRNA brings the required amino acid to the ribosome.
   (Names of specific codons, anticodons and their amino acids
   are not to be memorized)
5. Amino acids become attached by peptide bonds
6. To form the required protein.
