Four different nucleotides are used as building blocks. Which of the following can be used to distinguish one nucleotide from another?
each half of the original DNA molecule is joined with the new complementary DNA strand
providing the instructions for the traits of an organism
so that healthy daughter cells are produced, allowing the organism to continue growing
30%
hydrogen bonds
DNA contains codes for proteins, which are necessary for the growth and functioning of an organism
the nitrogenous base
A=T; C=G
Cells pass through a G2 checkpoint before entering mitosis. Ideally, if DNA damage is detected, the cells do not enter mitosis until the damage is repaired. Why is DNA damage repaired before cells enter mitosis?
