Question 1

replication

Answer 1

1. DNA chain unwound by special protein (helicase)
2. Missing strand rebuilt by another protein (DNA polymerase)
3. Find unmatched nucleotide strand

Question 2

transcription

Answer 2

1. DNA chain unwinds in region of interest (only a little)
2. Region transcribed using RNA nucleotides and protein (polymerase)
3. Transcript peels off and goes to ribosomes

Question 3

translation

Answer 3

1. Transcript threaded through ribosome
2. Ribosome reads transcript and creates protein

Question 4

DNA

Answer 4

• 4 total nucleotides
• very stable

Question 5

RNA

Answer 5

• not very chemically stable because of slight differences in nucleotides
• some virus store genes in RNA so mutate very quickly
• easy for mutations to happen so multiply really quick

Question 6

Protein

Answer 6

• diverse & versatile (20 in total)
• not complimentary
• 1 amino acid to correspond to 3 nucleotides added
• can copy DNA but not themselves
