DNA Basics
What is the shape of DNA?
Double Helix
What are the three phases of the cell cycle?
Interphase, Mitosis, Cytokinisis
What is the 3 main differences between DNA and mRNA?
DNA has 2 strands and mRNA has one strand. DNA is made of deoxyribose sugar and mRNA is made of ribose sugar. Thymine is used in DNA and Uracil is used RNA.
Sing the chorus of the Mitosis song!
"I P on the MAT a mitosis dat
Its an Interphase, Prophase, Metaphase what?!
Then Anaphase, Telaphase, Tell me what you got!
After Cytokinisis, a two cell dat!"
What does Transcription produce?
Nucleus
What are groups of three nucleotides called?
Codons
Which phase in ALL cell replication does the cell spend most of it's time?
Interphase
What are the two phases of Protein synthisis?
Transcription and Translation
What are the Subunits of DNA?
Base, Phosphate, and Sugar
What happens to the DNA before the cells divide?
The DNA is copied.
Where does translation take place?
The ribosome
Which phase of mitosis do the chromosomes line up together?
Metaphase
Where is the ribosome found?
In the Cytoplasm
What are the 4 different nucleotides of DNA and which one pairs with which?
Thymine, Adenine, Guanine, and Cytosine.
Thymine pairs with Adenine and Guanine pairs with Cytosine.
Why do cell's need to have a cell cycle? Give two reasons.
1. Because they grow and die
2. To reproduce.
What is protein made of (what are it's subunits?)?
Amino Acids
If the cell in Interphase is called the "parent cell" than what is the two cells in Cytokinisis called?
Daughter cells
What is a section of DNA that codes for a unique protein?
A gene
What type of molecule is DNA?
Nucleic Acid
What are the three parts of DNA replication? Explain each one.
1. An enzyme "unzips" the DNA into two halves.
2. Nucleotides found in the nucleus line up with the "unzipped" halves.
3. Each half eventually has a new matching side forming two identical DNA molecules.
What tells the tRNA which amino acid to bring?
The anticodon
Which mitosis phase does nuclear membrane reappear?
Telaphase
What does DNA stand for and what does RNA stand for?
Deoxyribose nucleic acid and Ribonucleic acid
