Cell Cycle
Cell cytoplasm divides.
What is cytokineses?
Longest phase of the cycle.
What is interphase?
In this phase, Chromosomes line up in the middle of the cell.
What is metaphase?
Humans have this many chromosomes.
46
Type of mutagen where physical substances cause mutations
What is Physical mutagen
The reason DNA replication is necessary.
What is so that each daughter cell has identical genetic information?
Reasons cell division is important.
What are growth, repair, and reproduction?
In this phase, spindle fibres disappear as the cell prepares for cytokinesis.
What is telophase?
In this phase, the cell has two nuclei.
What is telophase?
Type of mutagen where living organisms cause mutations
Biological mutagen
The cell grows and carries out normal activities.
This is DNA replication.
What is S phase? (synthesis)
also accept: What is when DNA copies itself?
The cell's chromosomes become visible and the centrioles move to opposite sides of the cell.
What is prophase?
Nuclear membrane starts to disappear.
What is prophase?
Two types of strands in DNA replication
Leading and lagging strands
The phase that includes G1, S, G2.
What is interphase?
In this phase the cell carries on its normal differentiation and protein synthesis.
What is G1 phase?
Chromatids are pulled apart and become single chromatid chromosomes.
What is anaphase?
Enzyme responsible for synthesizing a new DNA strand during DNA replication
DNA Polymerase
Enzyme that repairs the gaps in the lagging strand
Ligase
Cell preparation for division occurs.
What is the G2 phase?
Enzyme that unwinds DNA strand during replication
Helicase
In this phase, spindle fibers start to appear and attach to centromeres.
What is prophase?
Also accepted: Prometaphase
Type of mutagen where chemical substances that cause mutations
Chemical mutagens
Type of fragments on the lagging strand
