Question 3
Our cells have 23 pairs of chromosomes to replicate for cell division. While picking apples in the orchard, you accidentally cut your hand on a sharp twig. Your skin must make new cells to heal the cut.
What part of the cell cycle is shown and how many pairs of chromosomes are in the new formed cells?
a
M-complete cell division, 23 pairs chromosomes
b
G1 Checkpoint- checking cell size and for enough proteins, 46 pairs of chromosomes
c
S- duplication of the DNA, 23 pairs chromosomes
d
G2 Checkpoint- checking cell size and DNA replication, 46 pairs of chromosomes
c
S- duplication of the DNA, 23 pairs chromosomes
