Lecture 5

Question 0

What is a mesosome?

Answer 0

Attaches the circular DNA molecule to the cell membrane

Question 1

What does it mean when prokaryotic cells go through exponential growth?

Answer 1

They have a circular DNA strand that continually undergoes DNA replication so at optimal temperature it. an divide every 20-40 minutes

Question 2

Describe the steps in prokaryotic cell cycle

Answer 2

DNA is circular and not condense
DNA is replicated and the cell wall increases in size
the growth of the cell wall produces a septum
invagination splits into two cells in a process called partitioning
mesosome is recreated

Question 3

Describe the process of prokaryotic DNA synthesis

Answer 3

double stranded DNA is cleaved leaving a 3’ hydroxyl

RNA primer is syntheses from which DNA polymerase will make the complementary strand which requires type 11 topics erase

Question 4

Describe the protein complex on the eukaryotic chromosome

Answer 4

They are a group of proteins that bind to the DNA throughout the proteins They all contain their own origin of replication to which they bind
these are all simultaneously replicated (slightly sequential

Question 5

Describe what happens in prophase

Answer 5

centrioles duplicate
centrioles move to poles
chromosomes condense
mitoic spindle forms

Question 6

Describe what happens in anaphase

Answer 6

daughter chromatids seperafe and move to poles

Question 7

Describe what happens in metaphase

Answer 7

chromosomes move to equator

Question 8

Describe what happens I. telophase

Answer 8

membranes form around new nuclei

cytokinesis

Question 9

Describe what happens in interphase

Answer 9

The DNA is condensed and not visble

Question 10

In telophase what forms between the two cells

Answer 10

actin and myosin called absition

in plants it is called a cell plate
