Mitosis
Where Mitosis occurs
What is Diploid Cells?
Sperm and Egg cells
Gametes
what shape is DNA?
Double helix
What is transcription?
The process of making mRNA from DNA in the nucleus
Where does DNA replication occur in Eukaryotes?
the Nucleus
Number of cells that come out of this
2
Homologous chromosomes separate
What did Watson and Crick do?
Created a model of DNA structure
What is translation?
The process of using tRNA and mRNA to put together amino acids at the ribosome
When does DNA replication happen during the cell cycle?
S phase of interphase
Type of cells that come from this
identical
What happens in M2?
replicated chromatids seperate
What are the 4 nitrogen bases of DNA?
Adenine, Guanine, Cytosine, Thymine
What is the function of mRNA?
To bring the instructions to make a protein from the nucleus to the ribosome
Does DNA replication happen during mitosis?
No, before
Spindle fibers form in this stage
What is Prophase?
what is M1 divided into?
prophase 1, anaphase 1, metaphase 1, telophase 1
1
What is the function of tRNA?
Molecule that brings amino acids to the ribosome during translation
What are the key players in DNA replication?
helicase, DNA polymerase, Primase, ligase
What structure guides movement of chromosomes?
What are Spindle Fibers?
what is the purpose of meiosis?
to ensure genetic variation
What nitrogen base replaces Thymine in RNA?
Uracil
What is the function of rRNA?
Ribosomes are made of this molecule. Ribosomes make proteins.
What enzyme is the "unzipper"?
DNA helicase
