Paper 3(not sure)

Question 1

Name two techniques the scientists may have used when analysing viral DNA to determine that the viruses were close related.

Answer 1

• Gel electropherisis
• Genetic fingerprinting

Question 2

Determining the genome of the viruses could allow scientists to develop a vaccine. Explain how.

Answer 2

• could identify proteins derived from the genetic code
• identify potential antigens to be used in vaccines

Question 3

Describe the advantage of the Bohr effect during intense exercise

Answer 3

• increases dissociation for oxygen
• for aerobic respiration of tissues/muscles

Question 4

Describe how the HIV is replicated once inside helper T cell

Answer 4

• RNA is converted into DNA using reverse transcriptase
• DNA is inserted into the helper T cell’s nucleus
• DNA is transcribed into HIVmRNA
• HIV mRNA is translated into new viral proteins
