Structures
The shape of DNA molecule
What is a double helix?
The location of transcription in a eukaryotic cell.
What is the nucleus?
The location of translation in a eukaryotic cell.
What is at the ribosome in the cytosol?
Credited with creating the first model of DNA.
Who are Watson and Crick?
The type of bond that holds nucleotides together.
What are hydrogen bonds?
The end product of transcription.
What is mRNA?
The end product of translation.
What is a protein?
Used X-ray diffraction to create images of DNA but received little to no credit.
Who is Rosalind Franklin?
The type of bond that holds amino acids.
What are peptide bonds?
The individual units of DNA made of sugar phosphate and nitrogen bases.
What are nucleotides?
The mRNA strand that matches the DNA bases of GCTAATCAG
What is CGAUUAGUC?
The function of tRNA
What is to bring an amino acid to a ribosome?
Worked to develop the idea of a codon.
Who is Sydney Brenner?
The reason that nitrogen bases are complementary.
What is the chemical shapes only bond with each only one type (A-T has 2 bonds, C-G has 3 bonds)?
If there is 30% guanine in a section of DNA, how much cytosine is present?
What is 30%.
The difference in backbones between DNA and mRNA.
What is mRNA has one backbone while DNA has two backbones?
The function of rRNA
What is to "read" the mRNA message?
What ends protein production
What is a stop codon?
Set of three bases on a tRNA molecule
What is an anticodon?
If there is 10% of cytosine present in a DNA strand, how much thymine is present?
What is 40%?
When transcription will occur.
What is anytime the cell needs to build a protein?
The amino acid that will code for DNA codon AAG given . . .
AAG = Rain
UUC = Snow
TTC = Sun
UUG = Wind
What is snow?
The enzyme used to "unzip" DNA
What is RNA polymerase or DNA helilcase?
Determines the function of a protein.
