Steps of Meiosis 1

Question 1

List the he stages of meiosis 1 in order

Answer 1

interphase, prophase1, metaphase1, anaphase1,telophase1

Question 2

Explain interphase in meiosis 1

Answer 2

During interphase, DNA is replicated to produce sister chromatids

Question 3

what happens in prophase 1 during meiosis?

Answer 3

-chromosomes, shorten and thicken

-crossing over takes place which mixes genetic material

-Each sister chromatic intertwines with a sister chromatid from its matching homologous chromatid in a process called synopsis

-Nuclear membrane dissolves

-Spindle fibres form

-centrioles move to end of the cell

Question 4

what happens in metaphase 1 in meiosis?

Answer 4

-spindle fibres attach to the centrioles of the chromosomes
-homologous chromosomes (tetrads) lineup along the equator of the cell

Question 5

What happens in anaphase one in meiosis?

Answer 5

spinal fibres pull the tetri apart
Homologous pairs separate and move to opposite poles of the cell

Question 6

what happens in Tele phase one during meiosis?

Answer 6

-Cell divides into two

-Spinal fibres disappear

-Nuclear membrane forms around the sister chromatids

-Each daughter nucleus receives one member of the original chromosome pair
