DNA replication
where dose DNA replication take place
nucleus
how dose DNA mutation happen
Mutations can result from errors in DNA replication during cell division,
what is the growth phase called
G1
What are 3 things mitosis is essential for?
growth, repair, and asexual reproduction
what splits the DNA IN half
a DNA helicase
name one of the DNA mutations
insertion,deletion,substitution
what is after the g1 phase
s phase
What makes meiosis unique from mitosis?
contain only half as much DNA
what is DNA made of
four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C)
name all the DNA mutations
insertion,deletion, and substitution
how much growth phases are there
2
It is an asexual reproductive process that occurs in unicellular organisms.
What holds one strand against the other in the double helix?
Hydrogen bonds
Which DNA mutation is most damaging?
frameshift mutation
In what stage of the cell cycle do the chromosomes line-up?
metaphase
How many stages is mitosis?
five
When do cells duplicate their DNA?
S phase
What can increase the rate of mutation?
radiation
What takes up 90% of the cell cycle?
Interphase is the longest phase of the cell cycle, accounting for about 90% of the total cycle
Does mitosis ever end?
it continues throughout life to repair the body or replace cells that have died.
