Mitosis and Mieosis

Question 1

Name all the phases of Mitosis

Answer 1

1. Interphase
2. Prophase
3. Metaphase
4. Anaphase
5. Telophase
6. Cytokinesis

Question 2

What happens during Interphase

Answer 2

In this phase, the cell grows and develops. Chromosomes (DNA) are copied.

Question 3

What happens during Prophase

Answer 3

Chromosomes are visible during this phase because they are condensing. The nucleus is still visible and present.

Question 4

What happens during Metaphase

Answer 4

Spindle fibers attach to chromosomes. Chromosomes line up in the middle of the cell. M for middle

Question 5

What happens during anaphase

Answer 5

Chromosomes divide into two sets. Each half or set is pulled away to opposite sides of the cell. Sister chromatids are separated.

Question 6

What happens during telophase

Answer 6

Two nuclear membranes begin to form. The cell begins to separate

Question 7

what happens Cytokinesis

Answer 7

Cytoplasm divides. Two daughter cells with the same number of chromosomes.

Question 8

With respect to the whole cell cycle, how often do cells divide (Mitosis) and how often are they doing Interphase

Answer 8

They are doing interphase 90% and mitosis 10% of the time

Question 9

How many chromosomes do humans have

Answer 9

46 in each Nucleaus

Question 10

What are centromere

Answer 10

The centromere is part of the chromosomes where the sister chromatids are held together.

Question 11

What are chromatids

Answer 11

Chromatids are strands of replicated chromosomes.

Question 12

What are spindles

Answer 12

Spindles help move the chromosomes/ chromatids. These spindles are fibers.

Question 13

Meiosis does what?

Answer 13

Makes sperm and egg cells (gametes)

Question 14

How many chromosomes do sperm and egg cells have?

Answer 14

23

Question 15

What happens in prophase one

Answer 15

Along with what was previously stated. Chromosomes find their homologous pair. This means they are roughly the same size and share the same types of genes in the same location. The chromosomes then transfer genetic DNA.

Question 16

What happens in Metaphase 1

Answer 16

The chromosomes go to the middle. The difference between this and mitosis is the chromosomes are in pairs.

Question 17

What happens in Anaphase 1

Answer 17

The chromosomes are pulled away by the spindle fibers

Question 18

What happens in Telophase 1

Answer 18

It is apparent you will end meiosis one with two new cells then cytokinesis follows splitting the cytoplasm but this process is not over.

Question 19

What happens in prophase 2

Answer 19

spindles start to form

Question 20

What happens in Metaphase 2

Answer 20

In metaphase 2 the chromosomes line up in the middle but this time they are not in pairs.

Question 21

What happens in Anaphase 2

Answer 21

The chromatids are pulled away by the spindle fibers

Question 22

What happens in telophase 2

Answer 22

In telophase 2 the nuclei begin to appear and cytokinesis splits the cells into 4 new gametes

Question 23

at what stage in mitosis do you have two distinct haploid cells

Answer 23

telophase 1

Question 24

how does the production of gametes in biological males differ from biological females?

Answer 24

Male: Takes place in the testes, Begins at puberty, and continues throughout life.
Produces four sperm cells from each spermatocyte during spermatogenesis.
Sperm cells are small, highly mobile, and adapted for delivering genetic material to the egg.

Female; Takes place in the ovaries, Begins before birth, pauses during childhood, and resumes at puberty. It continues until menopause, but only one mature egg is typically produced per menstrual cycle, Produces one mature egg from each oocyte during oogenesis, The egg (or ovum) is relatively large and immobile, as it carries nutrients for potential fertilization and early embryonic development.
