DNA Structure
The molecular shape of DNA
What is a double Helix?
This molecule separates DNA strands before replication occurs
What is DNA helicase?
This phase of interphase is where normal cell growth occurs and the cell checks DNA before DNA replication
What is G1?
During this stage of mitosis, mitotic spindles pull DNA apart
What is anaphase?
DNA is condensed and stored in this form
What is a chromosome?
These bases are included in a DNA strand
What is A,T, C and G?
This stage of the cell cycle is where DNA replication occurs
What is the S-phase?
During this stage of the mitosis, 2 nuclei form
What is telophase?
What are phosphates, pentose sugar, and nitrogenous bases?
DNA replication occurs in this stage of the cell cycle
What is the S-phase ?
This stage of the cell cycle includes cell growth and preparation of the cell for Mitosis
What is G2?
These molecules attach to chromosomes to separate them
What are spindles?
DNA bases are paired by this type of bonds
what are hydrogen bonds?
This molecule attaches free nucleotides to create a complementary DNA strand based on the template strand
What is DNA polymerase?
A normal cell spends approximately this amount of its time in interphase
What is 90% ?
Spindle fibers extend from this structure
What are centrosomes?
This term is used to define DNA strands that are complementary and run in opposite directions
What is anti-parallel?
This can occur as a result of mismatch pairing of DNA bases
What are mutations?
These process do not occur during interphase when cancer develops in a cell
What are checkpoints and regulations?
4 purposes of mitosis
What are growth, regeneration, asexual reproduction, and cell replacement?
