Codons
What is the start codon?
AUG
What element is the single molecule difference between DNA and RNA?
Oxygen
What does a chromosome consist of?
DNA or genetic material
What does helicase do?
Unzips the DNA strands
What chromosomes are produced after genetic recombination?
Recombinant Chromosomes
6 nitrogenous bases (3 per codon)
What is the term that describes DNA having an original template strand paired with a new strand?
Semi-conservative
What protein is involved in the first coiling processes of DNA material to assist in packaging?
Histones
What removes the RNA primers from the new strand?
Exonuclease
What process binds two chromosomes together for genetic recombination?
Synapsis
How do you read a codon chart? what steps do you take?
left hand side first letter, top edge second letter, find intersecting box for the codon (or see right hand side for the third letter)
What is the demonstration Mr. Biggers taught you to remember nucleotides?
nucleotides with hands, one is upside down to allow fingers to connect
How many chromosomes vs. chromatids are in the following:
X X I I X
5 chromosomes
8 chromatids
What direction does DNA Polymerase read the template strand?
After synapsis, the two combined chromosomes can be referred to as what?
a tetrad
The first team to have one group member sitting on the floor with both hands raised above their head will be able to attempt to transcribe the DNA sequence on the board.
TAC GGA AAA ATA ATT
AUG CCU UUU UAU UAA
There are 5 carbons in the sugar involved in DNA. What is the sugar?
deoxy-ribose
46 chromosomes in somatic cells
23 chromosomes in gametes
Raising hands, what are the enzymes involved in DNA replication in order of their first appearance?
Helicase, Primase, DNA polymerase, Exonuclease, DNA Ligase
What is a major benefit of genetic recombination?
genetic variability in traits passed on
How many base pairs does the average person have in their body?
3 billion
The team that chose the category has 45 seconds to draw a pair of nucleotides on the board
Teacher will check drawing for points.
What are the steps of mitosis and how are chromosomes involved in each?
Prophase= DNA condenses into chromosomes
metaphase= chromosomes align in the middle
anaphase= chromosomes pulled apart (X-> I I)
telophase= chromosomes are at opposite ends of the cell
Recite AS A GROUP what phrase we said as a class describing what enzymes.
Enzymes are proteins that act as a catalyst to speed up the reaction (rate) by lowering the activation energy.
Choose another group to go 1 v 1 against
Teacher will explain the task
remaining groups judge to choose who won, teacher is tie breaker
