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...

Which bases pair in DNA? In the simulation below, build the strand that is complementary to the one shown. In this case, you are not replicating the strand but completing it. correct answer: Thymine Adenine Guanine Cytosine Cytosine Thymine Thymine Adenine Guanine Thymine To continue, click on the image that you think best represents how DNA normally looks in the cell. correct answer: First image Looking at the images, how many chromosomes are there in a typical human? correc...

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...

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 hete...
