Adenine and guanine are - Study guides, Class notes & Summaries

The structure of a strand of DNA. - Answer-it is a double helix, like a twisted ladder. the ladder rings are nucleotide subunits and they have a covalent bond to the sugar phosphate backbone (made of deoxyribose and a phosphate group) What are the nucleotide subunits? - Answer-adenine, guanine, cytosine, and thymine How are the subunits held together? - Answer-through a hydrogen bond What are the nucleotide subunits compliments? - Answer-Adenine and thymine cytosine and guanine How does D...

A - Alanine (1 letter) Activation of enzymes through ligand binding: why would this be useful? - The binding of a ligand to an allosteric site of a multimeric enzyme often induces positive cooperativity, that is the binding of one substrate induces a favorable conformation change and increases the enzyme's likelihood to bind to a second substrate. Ala - Alanine (3 letter) Arg - Arginine (3 letter) Asn - Asparagine (3 letter) Asp - Aspartic Acid (3 letter) Barr body and relation to heter...

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 bon...
