General Knowleage
DNA
What is the universal code for proteins used by all living things?
Where transcription take place.
What is in the nucleus
An mRNA codon is a sequence of these.
What are 3 Nitrogen Bases?
What tRNA anticodons would be needed to translate the sequence from mRNA in (UAG/CUA/UCA)?
What is AUC/GAU/AGU?
How many amino acids are there?
20
When a codon is substituted but still makes the same Amino Acid.
What is Silent mutation
proposed that DNA is a double helix
Watson and Crick
What is the structure difference in DNA and mRNA?
DNA is a double Helix, RNA is a single Helix.
Translation.
What is Step 2 of protein synthesis where tRNA brings the Amino Acid to the Ribosome to build a polypeptide?
Translation occurs here.
Cytoplasm
The codons that would pair with DNA in this strand (GGA/TCG/CCT).
What is CCU/AGC/GGA?
The Start and Stop Codons.
What are AUG (Start) and UGA, UAA, and UAG (Stop)?
When one amino acid is substituted for another.
What is a Missense substitution?
building blocks of proteins
amino acids
What are 2 parts of protein synthesis called?
What are Step 1 Transcription and Step 2 Translation
The three types of RNA
What are Messenger (mRNA), Transfer (tRNA) and Ribosomal (rRNA)
The organelle responsible for Protein Synthesis
What is the Ribosome?
The Amino Acids for these codons (AUG/GCC/UGG) form a polypeptide.
What are Met(methionine), Ala(Alanine), Trp(Tryptophan)?
DNA to mRNA:
A=>
T=>
C=>
G=>
What are U,A,G and C?
When we receive an early termination (Stop) code.
What is a Nonsense mutation
building blocks of nucleic acids
nucleotides
What sugars do DNA and mRNA have?
DNA has dioxyribose sugar and mRNA has ribose sugar.
Transcription
What is Step 1 of Protein synthesis where DNA writes the code on mRNA?
The Complementary strand uses Uricil instead of Thymine.
How does mRNA differ from DNA?
If a codon of mRNA codes for U instead of T, what would change in this strand (ATG/GCC/TGG)?
What is AUG/GCC/UGG?
Using a codon wheel what amino acid is UUG?
Leucine
AUG/GGC/AAC/CCG goes to
AUG/GCA/ACC/CG
Deletion
This scientist used X-ray diffraction to produce important evidence about the structure of DNA. Her famous Photo 51 provided evidence that DNA has a helical structure.
Who was she?
Rosalind Franklin
Where is DNA and mRNA located at?
DNA is found in the nucleus, mRNA is found in the nucleus for Transcription and carries the code cytoplasm for Translation
Where must an mRNA attach before protein production can begin?
mRNA must attach itself to a ribosome
Are Located at each end of the tRNA molecule.
What are the Anticodon and an amino acid?
What type of bond is formed between amino acids?
Peptide bonds
What is the difference between an amino acid and a protein?
Amino acids are the building blocks (Monomer). A protein is a chain of amino acids that are connected to each other (Polymer).
TAC – AAA – CGG – ATT
Transcribe the DNA into mRNA.
AUG – UUU – GCC – UAA
What enzyme is responsible for building an RNA strand during transcription?
RNA polymerase
