Central dogma Correct Answer-DNA -> RNA -> Protein Avery-MacLeod-McCarty experiment Correct Answer-demonstrated that DNA is the genetic material because degradation of DNA led to a cessation of bacterial transformation Nucleotides Correct Answer-Basic units of DNA molecule, composed of a sugar, a phosphate, and one of 4 DNA bases Key bonds in nucleotides Correct Answer-Glycosidic and ester bonds glycosidic bond Correct Answer-Between the base and the sugar forms at 1' Ester...

What is DNA? Correct Answer-A linear, double-stranded structure composed of multiple units of four different nitrogenous bases, each attached to a sugar molecule Bases are nucleoprotiens created from proteins we eat. They can be single ring structures (pyrimidines) or double-ring structures (purines). What are the pyrimidines and what are purines? Correct Answer-Adenine and Guanine are purines. Thymine and cytosine are pyrimidines What is the purpose of a gene? Correct Answer-To code for t...

What are the purines and pyrimidines? - Answer-purines: adenine, guanine pyrimidines: cytosine, uracil, thymine What are some examples of the cause of mutations in DNA? - Answer-cellular metabolism, UV light exposure, ionizing radiation, chemical exposure, replication errors What happens when the DNA is damaged/a mutation occurs? - Answer-cell cycle checkpoint activation, transcriptional program activation, DNA repair, apoptosis What is the definition of a gene? - Answer-A segment of D...

Central Dogma - ANSWER - DNA → RNA → Protein Purines - which bases? - how many rings? - ANSWER - Pyrimidines - which bases? - how many rings? - ANSWER - Remember: "Pyrimidine" has a "y" in it; so does "cytosine" and "thymine."

What are the 4 nitrogenous bases? Which pair together? Correct Answer-adenine (A), thymine (T), cytosine (C), guanine (G) A->T, C->G What are the issues with these combinations: 1.) Pyrimidine + Pyrimidine = 2.) Purine + Purine = 3.) Pyrimidine + Purine = Correct Answer-1.) width of DNA too narrow 2.) width of DNA too wide 3.) width of DNA consistent with X-ray model Which bases are purines and which are pyrimidines? Correct Answer-purines: A,G pyrimidines: T,C What are...
