DNA Replication
What is the mnemonic to remember how the nucleotides Adenine, Guanine, Thymine and Cytosine match up?
Apple in the Tree, Car in the Garage
A - T
C - G
The "unzipping/hacking" enzyme that unzips or breaks apart the double helix DNA.
Helicase
Where in the cell does transcription occur?
The nucleus (DNA cannot leave the nucleus)
tRNA
What is the first stage of mitosis?
Prophase
Which is nucleotide pairs with Adenine (A)?
Thymine (T)
The primary enzyme that plugs in the nucleotides (A,T,C,G) to compliment the DNA strand.
DNA Polymerase
In RNA, this nitrogenous base replaces thymine (T) to pair with adenine (A).
Uracil (U)
What is the amino acid for this tRNA:
CAA
GLN
What is the second stage of mitosis?
Metaphase
Write the matching pairs for this DNA strand:
A T T C G G T A A T G
T A A G C C A T T A C
The enzyme that acts like "liquid glue" and seals the DNA back together.
Ligase
Write the mRNA strand for this DNA strand:
DNA: A C C T A G C G G A T T A
mRNA: ?
mRNA: U G G A U C G C C U A A U
Which RNA codes for Lys?
AAA
AAG
What is the third phase of Mitosis? What is happening during this stage?
Anaphase, the chromosomes are being pulled apart.
During which phase of the cell cycle does DNA replication occur?
S Phase
If DNA polymerase fails to put the correct nucleotide (A,T,C,G), what disease or mutation can a person get?
Cancer
Write the tRNA strand for this DNA and mRNA strand:
DNA: A C C T A G C G G A T T A
mRNA: U G G A U C G C C U A A U
tRNA: ?
tRNA: A C C U A G C G G A U U A
What are the Amino Acids?
DNA: A C C T A G C G G A T T
mRNA: U G G A U C G C C U A A
tRNA: A C C U A G C G G A U U
THR-STOP
How many cells do you end up with at the end of Mitosis?
2
What does DNA stand for?
Deoxyribose Nucleic Acid
Why don't the whales get cancer?
They had long segmental duplicates in their DNA, that attacked cancer cells. Their bodies were able to kill cancer itself.
What is the purpose of mRNA?
To carry the "message" from DNA to the rest of the cell because DNA cannot leave the nucleus.
What are the Amino Acids?
DNA: A T A G C G A A T
mRNA: U A U C G C U U A
tRNA: A U A G C G A A U
ILE - ALA - ASN
What was the physical hand mnemonic for Mitosis? Demonstrate.
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
