mitosis and meiosis

Question 1

what is the cell cycle

Answer 1

series of events that take place in a cell that causes it to divide into two daughter cells

Question 2

what is the cell cycle in prokaryotic cells

Answer 2

binary fission

Question 3

what is the B period in binary fission

Answer 3

the period extends from the end of cell division to the beginning of DNA replication

Question 4

what is the C period in binary fission

Answer 4

the period required for chromosome replication

Question 5

what is the D period in binary fission

Answer 5

time between the completion of chromosome replication and the completion of the cell cycle

Question 6

what happens in the G1 phase

Answer 6

carries out its function

Question 7

what happens in S phase

Answer 7

dna replication and chromosomes duplication occur

Question 8

what happens in G2 phase

Answer 8

growth phase

Question 9

what happens during prophase

Answer 9

chromosomes condense into rodlike structures
each chromosome is doubled
centresone is generating the spindle as it separates
spindle forms

Question 10

what happens during pro metaphase

Answer 10

nuclear envelope breaks down
spindle enters
microtubules from opposite poles attach to the kinetochores of each chromosome

Question 11

what happens during metaphase

Answer 11

spindle is fully formed
chromosomes align on the metaphase plate

Question 12

what happens during anaphase

Answer 12

spindle septettes sister chromatids and moves them to opposite poles
chromosome segregation is complete

Question 13

what happens during telophase

Answer 13

new nuclear envelope forms around chromosomes
the cytoplasm is begging to divide from the cleavage furrow

Question 14

what is cytokenisis

Answer 14

when cleavage furrow fully separates the two daughter cells

Question 15

what does sexual reproduction require

Answer 15

fertilization event in which two haploid gametes unite to create a diploid cell called a zygote
