Die
200
What is the name of the monomer or subunit of DNA?
Nucleotide
200
During which phase of Interphase does replication occur?
S Phase or Synthesis Phase
200
Name the enzyme that carries out transcription. BE SPECIFIC
RNA Polymerase
200
At which organelle does translation occur?
Ribosome
300
In their original model, Watson and Crick had the ____________ and ____________ on the inside of the helix and the ___________ on the outside.
Sugars and phosphates, bases
300
DNA molecules are made up of two strands that run ______________ to one another.
Antiparallel
300
______________ adds the short RNA primer.
Primase
300
What is a codon? Include the purpose of a codon. Give an example.
A sequence of three nucleotides that code for each type of amino acid. (Anything as long it doesn't have a T)
300
In what part of the cell (NOT IN WHICH ORGANELLE) does translation occur?
Cytoplasm
400
What is the name of the image Rosalind Franklin produced that led Watson and Crick final DNA model?
Photo 51
400
Why does DNA polymerase need an RNA primer?
DNA Polymerase can only add nucleotides to a pre-existing strand
400
List the 3 major difference between DNA and RNA
1. U instead of T 2. Single stranded 3. Sugar is ribose instead of deoxyribose
400
The following is an anticodon: GUA Which would be the ultimate amino acid that matches this anticodon?
Codon: CAU--> Amino acid: Histidine
500
Why were bacteriophages the perfect microorganism to use when determining what the hereditary molecule is? (Think about what they're made of)
Bacteriophages are made up of only DNA and Proteins--> scientists were trying to determine if proteins or DNA were the hereditary molecule.
500
How many carbon rings does a purine have? Pyrimidine? Which bases are the purines? Which bases are the pyrimidines? MUST HAVE ALL PARTS TO GET THE POINTS
Purine: 2 rings; Pyrimidine: 1 ring Purines: A and G; Pyrimidine: C and T
500
_____________ is the enzyme that links the _____________ strands together. These shorts strands are more specifically known as __________ ___________.
Ligase, lagging, Okazaki fragments
500
Transcribe the following strand of DNA into mRNA. Circle each codon in the resulting mRNA transcript. T A C C C G T C A C A G A T T
A U G G G C A G U G U C U A A ____ ____ ____ ____ ____

How does the cell/ribosome ensure the correct amino acid is added to a growing amino acid chain?
The anticodon on a tRNA matches up with the codon on the mRNA. The correct tRNA molecule is carrying an amino acid that corresponds to the mRNA codon.
