Chapter 10.1: Bacterial Cell Division

Question 1

Define binary fission

Answer 1

asexual reproduction by division of one cell or body into two equal or nearly equal parts

Question 2

After As the DNA is replicated, the cell elongates, and the DNA is partitioned in the cell such that the origins are at the ¼ and ¾ positions in the cell and the termini are oriented toward the middle of the cell, what is the next step of binary fission?

Answer 2

Septation the begins, in which new membrane and cell wall material begin to grow and form a septum at approximately the midpoint of the cell
• A protein molecule called FtsZ facilitates this process

Question 3

After the bacterial DNA molecule replicates, what is the next step of binary fission?

Answer 3

The replication enzymes move out in both directions from that site and make copies of each strand in the DNA duplex. The enzymes continue until they meet at another specific site, the terminus of replication

Question 4

Define septation

Answer 4

in prokaryotic cell division, the formation of a septum where new cell membrane and cell wall is formed to separate the two daughter cells

Question 5

What is a wall between two cavities?

Answer 5

septum

Question 6

Define septum

Answer 6

a wall between two cavities

Question 7

After The replication enzymes move out in both directions from that site and make copies of each strand in the DNA duplex. The enzymes continue until they meet at another specific site, the terminus of replication, what is the next step of binary fission?

Answer 7

As the DNA is replicated, the cell elongates, and the DNA is partitioned in the cell such that the origins are at the ¼ and ¾ positions in the cell and the termini are oriented toward the middle of the cell

Question 8

After Septation the begins, in which new membrane and cell wall material begin to grow and form a septum at approximately the midpoint of the cell, what is the next last of binary fission?

Answer 8

When the septum is complete, the cell pinches in two, and two daughter cells are formed, each containing a bacterial DNA molecule

Question 9

What is in prokaryotic cell division, the formation of a septum where new cell membrane and cell wall is formed to separate the two daughter cells?

Answer 9

septation

Question 10

What is the first step of binary fission?

Answer 10

Prior to cell division, the bacterial DNA molecule replicates.
• The replication of the double-stranded, circular DNA molecule that constitutes the genome of a bacterium begins at a specific site, called the origin of replication

Question 11

What is asexual reproduction by division of one cell or body into two equal or nearly equal parts?

Answer 11

binary fission
