Nucleic Acids

QuestionAnswer
What is the Chemical Structure of DNA? Deoxyribose Nucleotides = Deoxyribose Sugar, Pi and an Organic Base
What is the shape of DNA? Double Helix - held together by WEAK Hydrogen bonding between Complimentary Bases
What part of the cell makes DNA? DNA is Self-Replicating - given proper environmental conditions
What is the structure of RNA? Ribose Nucleotides = Ribose (sugar), Pi, and an Organic Base
What is the shape of RNA? Mostly single Helix - no regular base pairing
When is RNA a double Helix? when it folds back on itself
What are the 3 functional types of RNA? mRNA, tRNA, rRNA
Which Nucleic Acid is BIGGER? DNA is bigger than RNA
What determines the order that AA are lined up in the Protein Product? the SEQUENCE of Pyrimidine/Purine Bases
Why would a Genetic Code reading bases in groups of 1 or 2 be unworkable? 1:4 or 2:16 or 3:64
What is the name for the 3 letter words coding for AA in DNA? Triplets
Can 1 AA be represented by more than 1 Triplet? Yes. There are more Triplets than there are Amino Acids
Can 1 Triplet represent more than 1 AA? No. Reliability and consistencey are needed
Do all Triplets code for Amino Acids? NO. some are Start/Stop Triplets
Name the Pyrimidine Bases. Cytosine, Uracil, Thymine
