RRR…Replicate 10 Name the three enzymes involved in Replication in the order they are used.
RRR…Replicate 10: Answer Helicase, DNA Polymerase, Ligase
RRR…Replicate 20 Which step is Helicase used in and what does he do?
RRR…Replicate 20: Answer 1 st : unzips and unwinds the DNA separating the hydrogen bonds between bases
RRR…Replicate 30 During which step do we use Ligase and what does it do?
RRR…Replicate 30: Answer 3 rd step: glues the nitrogen base pairs together
RRR…Replicate 40 During which step do we use DNA Polymerase and what does it do?
RRR…Replicate 40: Answer 2 nd step: matches free nucleotides according to the base pair rule
RRR…Replicate 50 List all three steps in order naming the enzyme and its job.
RRR…Replicate 50: Answer 1)Helicase: unzips and unwinds the DNA separating the bases 2)DNA Polymerase: matches free nucleotides according to the base pairing rule 3)Ligase: glues the bases back together
Mutants 10 What type of mutation causes no change in the amino acid sequence and usually goes undetected?
Mutants 40 Give an example of a Beneficial mutation and tell how its beneficial.
Mutants 40 Answer Hypermobility Lactose Tolerance Sickle cell anemia vs. Malaria **Answers may vary.
Mutants 50 Your original DNA should produce these amino acids: DNA: TACACCTTGACT mRNA: AUGUGGAACUGA MetTrpAsnSTP Code out this DNA and find the mutation: DNA: TACATCTTGACT mRNA:____________________ AminoAcids:________________________ Type of Mutation:_____________/______________
Mutants 50 Answer Code out this DNA and find the mutation: DNA: TACATCTTGACT mRNA:_AUGUAGAACUGA_ AminoAcids:_MetSTP_ Type of Mutation:_Point_/__
The two Ts 10 Which T occurs inside the nucleus?
The two Ts 50 Explain: three steps of Transcription (use the enzymes) five steps of Translation (how does the whole process happen?)
The two Ts 50 Answer Transcription: 1)Helicase breaks apart DNA strands 2)RNA Polymerase matches up RNA nucleotides 3)Newly created mRNA strand heads to the ribosome Translation: 1)1 st mRNA codon enters the ribosome 2)tRNA brings the complimentary anticodon 3)Attached to the tRNA anticodon is the appropriate amino acid 4)Consecutive amino acids are joined together by peptide bonds 5)Resulting chain of amino acids is a protein
