Central Dogma - correct answerDNA-(Transcription) - RNA- (Translation) -Protein DNA Structure - correct answer1. Deoxyribose: 5 Carbon atoms are numbered 1' to 5' . Hydrogen attached to 2'. Sugar 2. Phosphate group Sugar-Phosphate backbone is asymmetric because PO4 groups connect the C5' of a sugar with the C3' of neighbouring sugar. = Asymmetric ends because the C5' end is attached to a PO4 and the C3' end is simply a hydroxyl group of the sugar. 3. Nucleic Acid: No-covalently bonded to ...

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...

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...
