DNA Vs. RNA

Question 1

DNA

Answer 1

of copies made is 1

• Requires a primer
• Lifetime of the cell
• Requires both DNA strands to replicate
• Number of copies vary but more than 1
• Uses Thymine

Question 2

RNA

Answer 2

• Doesn’t need a primer
• Lasts up to 10 hours
• Needs only 1 strand of DNA
  -Number of copies vary but more than 1
  -Uses Uracil

Question 3

Both

Answer 3

• Uses DNA as a template
• Must separate strands to access template
• Uses 3 tep process of initiation, elongation and termination

Question 4

Mutations

Silence

Answer 4

• Change nucleotide
• Silence → mutations results in coding for same amino acid
  Does Not change amino acid, has no effect
• At the 3rd position

Question 5

Mutations

Nonsense

Answer 5

• Changes to a stop codon
• Truncated protein
  
  • Cuts off amino acid chain
  • Less effects when happens at the end

Question 6

Mutations

Missense

Answer 6

• Can happen in the first two codons
• Changes amino acid that it is coded for

Question 7

Mutations

Frameshift

Answer 7

• Changes the open reading frame
• Changes all of the amino acid sequence

Question 8

Point substitution

Answer 8

• Changing a single nucleotide
• One codon
  Silent mutation
• Usually at the 3rd position of the codon
