Question 1

T/F: Inheritance patterns are based on changes in the genetic sequence.

Answer 1

False, based on changes in the packaging, not the genetic sequence

Question 2

What does a Code Reader Complex do?

Answer 2

Reads the histone code

Question 3

T/F: Histone code is unchangeable.

Answer 3

False, changes as the cell needs

Question 4

Why is having more copies of a gene better?

Answer 4

Less need for few mutations

Question 5

What is the term for a duplicated gene that has been irreversibly inactivated by multiple mutations.

DNA polymeraseDNA primaseDNA helicasessDNA binding protein

Question 7

What does DNA helicase do?

Answer 7

Unwinds parent strand of DNA

Question 8

What does DNA polymerase do and what are its two components?

Answer 8

Synthesizes the new DNA strand.Loading clamp and sliding clamp

Question 9

What does DNA primase do?

Answer 9

Creates starting points for DNA synthesis from parent strand

Question 10

What does ssDNA binding protein do?

Answer 10

Binds to ssDNA to prevent parent strands from joining back together

Question 12

What type of junctions does homologous recombination create?

Answer 12

Holliday junctions

Question 13
