cell division, meiosis & mitosis

Question 1

what is the process for mitosis?

Answer 1

a cell is taken ➡️ chromosomes in nucleus make clones ➡️ chromosomes line up in centre of cell ➡️ copies operate and move ➡️ cell splits in two ➡️ forms 2 daughter cells

Question 2

what happens to the 46 chromosomes?

Answer 2

somatic cell of 46 ➡️ doubles to get 92 called DNA replication ➡️ 92 splits in half foe cell division of 2 sets of 46 ➡️ now have 2 genetically identical daughter cells

Question 3

is there 1 or 2 parents with mitosis?

Answer 3

1

Question 4

does meiosis have 1 or 2 parents?

Answer 4

2 ➡️ 23 chromosomes from each = 46 altogether

Question 5

what is the process of meiosis?

Answer 5

cell duplicates its DNA ➡️ in 1st division chromosomes pair and line up ➡️ pairs are pulled apart ➡️ some chromosomes from each parent go into new cell ➡️ 2nd division chromosome line up in middle again ➡️ arms of chromosomes pulled apart ➡️ 4 gametes produced
