9.1: Most cell division results in genetically identical daughter cells

Question 1

cell division

Answer 1

reproduction of cells, only one part of the cell cycle

Question 2

Cell cycle

Answer 2

the life of a cell and how it divides

Question 3

How is DNA distributed in cell division?

Answer 3

Cell division can consist of the distribution of identical genetic material/DNA into 2 identical daughter cells

Question 4

Genome

Answer 4

All the DNA/chromosomes in a cell, DNA in a genome varies in number depending on the type of cell

Question 5

Chromosomes

Answer 5

packets of DNA

Question 6

Chromatin

Answer 6

DNA and protein, only found in eukaryotes, are in this state before they coil into chromosomes

Question 7

Somatic cells, what are the number of chromosomes

Answer 7

also known as body cells, they are diploid(2sets)/non-reproductive cells, have 2 sets of chromosomes=46

Question 8

Gametes, what are the number of chromosomes

Answer 8

also known as sex cells, they are haploid(1set)/reproductive cells: sperms 23 and eggs 23, have one set of chromosomes

Question 9

what must happen to the DNA before the cell divides

Answer 9

The DNA is replicated and chromatins become chromosomes

Question 10

sister chromatids

Answer 10

each duplicated chromosome has these and is joined copies of the original chromosome, become chromosomes when they split

Question 11

centromere

Answer 11

where 2 chromatids are most closely attached, like staples, and where the kinetochores lye

Question 12

What are the 2 phases of the cell reproduction

Answer 12

Mitosis and cytokinesis

Question 13

Mitosis

Answer 13

the first part, the division of genetic material or DNA in the nucleus, can cause growth and repair

Question 14

Cytokinesis

Answer 14

the second part, the division of the cytoplasm/enzyme-rich stew

Question 15

what is the mitosis for gametes

Answer 15

meiosis makes 2 nonidentical daughter cells as opposed to mitosis
