Structure and Function
(Part 1)
(Part 1)
The four bases of DNA (no abbreviations!)
What is Adenine, Guanine, Cytosine, Thymine?
DNA and RNA are this macromolecule
What is a nucleic acid?
What is the final product of transcription?
mRNA
The two categories of mutations
What are a point mutation and a frameshift mutation?
The structure of DNA
What is a double-helix?
The ratio of purines to pyrimidines in a strand of DNA
What is a 1:1 (one to one) ratio?
What are the three types of RNA?
What is rRNA, tRNA and mRNA?
A segment of three nucleotide bases is called a
What is a codon?
The type of mutation most likely to cause this change:
Val-Iso-Ala-Asp-Gly ---> Val-Iso-Cys-Phe-Leu
What is a frameshift mutation?
The three parts of a nucleotide
What is a sugar, phosphate group and nitrogenous base?
The name of the sugar in RNA
The base pairing rules for RNA
Uracil <--> Adenine, Cytosine <--> Guanine
Transfer RNA codes for this
The three types of point mutations
What are missense, nonsense, and silent mutations? (Must have all 3 to get the points)
The function or purpose of a nucleic acid
What is to store genetic information?
The type of macromolecule that RNA produces.
What is a protein?
Where does the mRNA molecule go after transcription is completed?
It leaves the nucleus and goes to a ribosome
What specific type of mutation is this? Use your codon chart.
DNA: TAC AAT AGA
Mutated DNA: TAC ATT AGA
What is a nonsense mutation? ("Substitution" as an answer is not specific enough)
The people awarded the Nobel Prize for discovering the structure of DNA
Watson and Crick
The name for this series of steps: DNA --> RNA --> Protein
What is central dogma?
What type of molecule is uracil? (Hint: the word ends in -ine)
What is a pyrimidine?
Using this segment of tRNA and a codon chart, find the correct amino acid: UAC
What is methionine or start codon?
What specific type of mutation is this? Use your codon chart.
DNA: TAC AAT AGA
Mutated DNA: TAC AAC AGA
What is a silent mutation? ("Substitution" as an answer is not specific enough)
