Biology 6.1.3.

Question 1

DNA sequencing

Answer 1

the process of determining the precise order of nucleotides within a DNA molecule.

Question 2

Germ line cell gene therapy

Answer 2

altering the genes in gametes, so the change can be passed onto offspring.

Question 3

Recombinant DNA

Answer 3

DNA combined from two sources/ organisms.

Question 4

Restriction enzyme

Answer 4

an endonuclease which cuts DNA at palindromic base sequences to reveal sticky/ blunt ends.

Question 5

Somatic cell gene therapy

Answer 5

altering the genes in body cells, which cures the genetic disease in one individual so the change cannot be passed onto offspring, where repeat treatments may be needed.
