DNA STRUCTURE AND REPLICATION QUIZ

Erythromycin

All of these

Tunicamycin

Bleomycin

is required only at the oriC site

performs the same function as helicase in eukaryotes

can be inhibited with antibiotics

adds positive supercoils to chromosomal DNA

M phase

G1 phase

S phase

G2 phase

All of these

The many different amino acid R groups on proteins confer many different shapes.

DNA has one main function in cells whereas proteins have many.

Some S amino acids cause proteins to bend; others cause protein to flatten.
