DNA

100

What is the shape of DNA called?

Double Helix

200

What does DNA stand for?

Deoxyribonucleic Acid

300

What is the bond called that holds two nitrogenous base pairs together?

Weak Hydrogen Bonds

400

What is the process called where DNA makes an exact copy of itself?

DNA Replication

500

If 30% of a specific DNA sequence are “G”, what percentage will be “A”?

20% of Adenine 

RNA

100

Every three bases on mRNA is called a _________.

Codon

200

If the mRNA codon is UAG, then what is its complimentary tRNA anticodon?

AUC

300

What are the steps to DNA Transcription?

Attach, Start, Slide, Stop

400

What is the name of the enzyme responsible for creating mRNA and what is that process called?

RNA polymerase, transcription

500

What enzyme function is needed for RNA polymerase to start its job?

Nothing, RNA polymerase both unwinds and recruits nucleotides for mRNA

Fun with Genetic Code

100

True or False

Earthworms use the same genetic code as humans.

True

200

Proteins are made up of long chains of __________.

Amino acids called Polypetides

300

If a frameshift mutation from exposure to radiation caused a segment of RNA to change from AUC to UAG, what would happen to the protein during translation?

It would stop

400

What amino acid would pair up with the beginning DNA bases TAC? and Why is it important?

Methionine

500

If exposure to radiation caused a segment of DNA to change from TTC to TTT, what would happen to the protein during translation?

Nothing would happen

Transcription & Translation

100

The process where mRNA copies the genetic code from DNA is called __________.

Transcription

200

If the tRNA anticodon is CGC, then what is the amino acid?

Ala; Alanine

300

Where does translation take place?

Within the cytosol; In the cytoplasm at a ribosome

400

Is mRNA or tRNA used to code for an amino acid and why?

mRNA because it is made from DNA and carried the original genetic information that the ribosome will use to make protein. tRNA just delivers the building blocks 

500

Name the steps to DNA Translation?

Attach, Start, Slide, Stop

Cell Division

100

What is the overall purpose of Meiosis?          A. To create two identical diploid daughter cells
B. To create four different haploid daughter cells
C. To create two different diploid daughter cells
D. To create four identical haploid daughter cells

What is the or of the steps in Mitosis?

PMAT

200

What is the steps in Mitosis plus seperation?

Prophase Metaphase Anaphase Telophase/Cytokinesis 

300

During which phase does Crossing-Over occur? Why is it important

Prophase I. Genetic Diversity

400

Guess a number between 1-10. If you guess right your team gets 200 points. If you guess wrong you will select a team to receive 200 points

4

500

What are two important things about cell cycle?

Interphase is when DNA is replicated

Cell Cycle regulates growth and development of a cell.
