Cell Cycle
DNA Replication
Reproduction
Meiosis & Mitosis
Protein Synthesis
100
This phase makes up the majority of the cell life cycle.
What is interphase?
100
This enzyme "unzips" the DNA strand.
What is helicase?
100
A cell that has TWO copies of each chromosome. In humans, these cells have 46 chromosomes.
What is a diploid cell?
100
This acronym helps us remember the phases of mitosis.
What is PMAT?
100
Proteins are made up of strings of ________.
What are amino acids?
200
The cell divides into two cells at this point in the cell cycle.
What is mitosis?
200
This enzyme "seals" the gaps in each new DNA strand.
What is ligase?
200
A cell that only has ONE copy of each chromosome. In humans, these cells have 23 chromosomes.
What is a haploid cell?
200
This stage in mitosis is when chromosomes line up in the middle of the cell.
What is metaphase?
200
This molecule cannot leave the nucleus, so an mRNA strand is made instead.
What is DNA?
300
DNA makes a copy of itself in this phase of interphase.
What is the S phase (synthesis phase)?
300
This enzyme adds complimentary nucleotides to the template DNA strand.
What is DNA polymerase?
300
When bacteria make identical copies of themselves, this is an example of ____________.
What is asexual reproduction?
300
This process introduces genetic variation to gametes produced in meiosis.
What is crossing over?
300
This molecule "reads"mRNA three nucleotides at a time.
What is tRNA?
400
This stage in the cell cycle occurs when the cytoplasm separates in the two developing cells and the cells move away from each other.
What is cytokinesis?
400
This enzyme makes sure the DNA polymerase knows where to start.
What is primase?
400
An advantage of this mode of sexual reproduction is that each offspring is genetically unique.
What is sexual reproduction?
400
This process in mitosis is when chromosomes condense and the nucleus dissolves.
What is prophase?
400
This type of codon tells the ribosome to stop translating the mRNA sequence.
What is a stop codon?
500
This can occur when something wrong happens in the cell cycle and the cell is unable to divide properly.
What is cancer?
500
There are four enzymes involved in DNA replication. These enzymes are (in order):
What is helicase, primase, polymerase, and ligase?
500
These types of cells are involved in sexual reproduction.
What are gametes (sperm & egg cells)?
500
What is meiosis?
500
This nucleotide is in RNA, but NOT DNA. (FULL NAME)
What is uracil?
