1

What subphase is when cell size increases in interphase?

G1

2

A requirement that a cell must be attached to a substratum in order to divide.

Anchorage dependence

3

What is a display of the chromosome pairs of a cell arranged by size and shape

Karyotype

4

What unwinds DNA ahead of replication fork?

topisomerase

5

What includes genes that determine the individuals ex?

sex chromosomes

6

What is the complete set of an organisms genes known as?

the genome

7

The process of nuclear division that results in 2 diploid cells

mitosis

8

What unzips DNA strands?

Helicase

9

The synthesis of two daughter DNA molecules from one original parent molecule is caLLED

DNA replication

10

where do light reactions occur?

thylakoids

11

What is the phase of meiosis that may or may not happen and results in a a second round of prophase, metaphase and all that shit?

Interkinesis

12

What is the organelles that is the site for preotein synthesis?

Ribosome

13

What phase of mitosis is when the nuclear envelope begins to break down and microtubules attach to chromosomes?

Prometaphase

14

Which phase results in bigger cell size and replication of DNA?

Interphase

15

when two original strands of the molecule separate, and each strand acts as a template for the synthesis of a new complementary strand it is known as what?

semi conservative replication

16

What phase of mitosis do chromosomes line up in a line at the center of a cell?

metaphase

17

the process of nuclear division that results in four haploid cells?

what is meiosis

18

Phases of mitosis and order?

Interphase Prophase (condensing the dna) Metaphase (middle phase, lining up the dna) Anaphase (away ohase where the dna begins to split) Telophase (gettiong really split that u need a telophone to call the other chromosomes) Cytokinesis a seperate membrane forms

19

synapsis of chromosomes occurs during

Prophase I

20

The phase of mitosis when sister chromatids are seperated?

Anaphase

21

Stabilizes the replication fork so replication an occur?

Single Stranded DNA binding proteins

22

Normal animal cell that stop dividing when they come into contact with one another is because of what?

Density dependent Inhibition

23

Where does citric acid cycle occur?

Mityochondrial martrics

24

Where does glycolysis occur?

Cytosol

25

A mutated gene that can cause cancer is called what?>

Oncogenes

26

What are homologous chromosomes?

basically two identical chromosomes

27

genetic exchange of small segments of DNA between non identical chromatids

What is crossing over

28

What does it mean to be heterozygous?

It means it has two different alleles

29

What are the 3 sub phases of interphase?

G1 G2 AND S

30

Which phase of mitosis is the longest ?

Interphase

31

What is the movement of material from an area of hisgh to low concentration?

Diffusion or passive transport

32

When one half of daughter DNA is conserved from parent strand and the other is a new daughter strand, what do we call that?

Semi conservative replication

33

The nuclear division of a diploid cell that results in four haploid cells?

meiosis

34

What organelle aids in intracellular digestion?

Lysosome

35

A process that creates new alleles to affect genetic diversity in a population?

mutation

36

What subphase of interphase is when DNA is replicated?

S Phase

37

What is the term that describes a trait that is controlled by m,any genes?

Polygenic

38

Dna is copied during what phase?

The S phase of interphase

44

chromatids remain attached to one another until anaphase

Centromere?

45

How does it end up having variations in offspring?

reshuffling or alleles
