BIO 30 molecular genetics quiz 1 (DNA replication)
Exam Questions with Correct Answers
1. for a molecule to heredity it must be able to control protein and
enzyme production- why? (Part 1) correct answers: PROTEINS because they make up
enzymes and are building blocks for the structure and EZYMES because they are catalyst which
allow cells to live long enough to reproduce by assisting chemical reactions)
2. for a molecule to heredity it must self replicate - why? (part 2) correct
answers: heredity material must be able to copy itself so that the resulting cells continue
to function properly
3. for a molecule to heredity it must change (or have mutability) - why?
(part 3) correct answers: in order from organisms to grow and develop it so... their genetic
material must be able to change
4. for a molecule to heredity it must be found in the nucleus - why?
(part 4) correct answers: without the nucleus the cell cannot undergo division
5. in Griffiths experiment with pneumonia why did the pneumonia
virus appear in the rat after heat killing the harmful virus correct answers:
because DNA is a transforming principle
6. what does the transmissions of genetic material depend on correct
answers: DNA molecules
7. where is DNA found and what does is initiate correct answers: in the
nucleus - protein synthesis
8. where does protein synthesis happen correct answers: in the nucleus and
cytoplasm
9. what transfers information during protein synthesis from the
nucleus to the cytoplasm correct answers: MRNA (messenger RNA)
10. what is a nucleotide composed of correct answers: phosphate, sugar-
deoxyribose, nitrogen base
11. what does the structure of DNA consist of correct answers:
nucleotides
12. when DNA replication is being preformed where does the
