Mitosis and Meiosis

The Cell Cycle

100

The majority portion of the cell cycle

Interphase

200

The portion of the Cell Cycle commonly known as Cell Division; consists of Mitosis and Cytokinesis

M-phase

300

The three portions of Interphase, as singular letter (and number) abbreviations

G1, S, G2

400

DNA is in this form during Interphase

chromatin

500

The portion of the cell cycle that includes the division of the genetic material

Mitosis

n vs. 2n

100

one set of chromosomes

haploid

200

2 sets of chromosomes, 1 from each parent

diploid

300

if an organism has 31 chromosomes in its gametes, what is it's diploid number? Answer must use proper notation. 

2n=62

400

n=19, how many chromosomes are in a diploid cell?

38

500

Mitosis and Meiosis both start with ___ cells. 

diploid 

Mitosis

100

List the phases of mitosis in order

PMAT

(incorrect if interphase or cytokinesis are mentioned)

200

the end product of mitosis

2 identical (2n) daughter cells

300

What can we say about the shape of the cell during anaphase?

it gets longer

400

The phase after the last phase of mitosis, that completes cell division

cytokinesis

500

In telophase:

1. chromosomes ________ to _______

2. the nuclear membrane _________

3. the cell membrane __________

1. chromosomes decondense to chromatin

2. the nuclear membrane reforms

3. the cell membrane (starts to) pinch in​​​​

Meiosis

100

Meiosis has how many rounds of Interphase?

1

200

The end product of meiosis

4 gametes 

(non-identical, haploid daughter cells) 

300

How do we describe the chromosomes that line up next to each other during Metaphase I and subsequently split during Anaphase I?

Homologous Pairs

400

What separates in Meiosis II?

Sister Chromatids

500

Before crossing over can occur, ____________  ______ must overlap to form a ______, and the resulting chromosomes (S.C's) are now referred to as _____________

Homologous pairs, tetrad, recombinant

AP Content

100

The cell cycle has _________ that halt the progression of the cell cycle if something is not right. (the generic term; not the enzyme/enzyme complex)

checkpoints

200

Mitochondrial DNA, and those associated traits are only passed on by which parent?

Mom

300

In Meiosis, when chromosomes separate incorrectly, it is called nondisjunction. A common example of this is Down Syndrome, marked by the trisomy of which chromosome pair? 

trisomy 21

400

specific protein that halts the cell cycle if there is damage (activated by cyclins and CDKs)

p53

500

The cytoplasm is distributed unequally in egg cells during meiosis; producing 1 __ and 3 __; name either. 

oocyte or polar bodies
