Translation

Question 1

1.

Answer 1

mRNA attaches to ribosome and it moves along one codon at a time.

Question 2

2.

Answer 2

tRNA brings a specific amino acid to the ribosome with a complementary anticodon to the mRNA codon. They bind via complementary base pairing.

Question 3

3.

Answer 3

A second tRNA attaches and a peptide bond forms between the two amino acids. First tRNA leaves ribosome to collect another amino acid.

Question 4

4.

Answer 4

When a stop codon appears, the chain ends as it doesn’t code for an amino acid.

Question 5

Transcription

Answer 5

mRNA produced, DNA unwinds from middle, only one gene of DNA copied, RNA nucleotides used (U), RNA polymerase used.

Question 6

DNA replication

Answer 6

DNA produced, DNA unwinds from one end, whole length of DNA copied, DNA nucleotides used (T), DNA polymerase used.
