Cell Cycle
What is the First Phase of the Cell Cycle
Interphase
What does the Helicase do in DNA Replication?
The Helicase unwinds the DNA double helix into two separate strands
What is the First phase of Mitosis
Prophase
What is the energy source that helicase uses to unwind the DNA double helix?
ATP
What is Cancer.
What Phase of the Cell Cycle replicates DNA enzymes.
S Phase
What is the main job of DNA polymerase?
Add nucleotides to the DNA strand
1. In which phase is the new daughters cell seen.
2. In which phase is the daughters cell almost completely separated.
1. Anaphase
2. Telophase
Why is the primate more active on the lagging strand than the leading strand?
The lagging strand is synthesized in fragments and needs more primers
Is Cancer Curable?
Yes
1. What phase does the cell grow and get ready for DNA replication
2. What phase does the cell grow and get ready for Mitosis
1. G1
2.G2
What is the main job of the DNA Ligase
Connects Okazaki Fragments Together to make a full set.
In which phase of Mitosis do the chromatids line up in the middle of the cell
What type of bond holds DNA bases together?
Hydrogen bond
Is a tumor cancer
No but can grow into one.
What Phase does the cell not grow or replicate but does normal cell functions in the body.
G0 phase
Why is an RNA primer necessary in DNA replication?
To start DNA synthesis
Prometaphase
Which base pairs with adenine (A) in DNA?
Thymine(T)
What is a Malignant
Malignant is another name for Cancer in which there is uncontrolled cell growth and it invades other tissue throughout the body.
What occurs during the M phase. (You have to list every single part of the M Phase) No points if a single one is wrong.
A new Daughter cell is made and the parts are - Prophase, Prometaphase, Metaphase, Anaphase, Telophase, Cytokinesis.
Which strand of DNA does helicase move along during replication, and in which direction?
Leading strand, 3' to 5'
1. Which phase in Mitosis is longest.
2. Which phase in Mitosis is shortest
1. Prophase
2. Anaphase
What are the four DNA bases.
adenine (A), cytosine (C), guanine (G), and thymine (T).
describe the 4 stages of Cancer.
1. Small Tumor in one area
2. Tumor has grown large and possibly spread to lymph nodes
3. Tumor has grown into tissues and lymph nodes
4. Cancer has spread throughout the body parts and other parts of the body
