Structure of DNA
Karten in diesem Stapel (9)
- 1What is DNA made up of?Two strands of nucleotides, each are extremely long and joined together by hydrogen bonds between complementary bases
- 2Which are the single-ring bases and which are the double-ring bases?Single-ring = T and C
Double-ring = A and G - 3What are the complementary base pairs and how many hydrogen bonds are they paired by?A and T - two hydrogen bonds
C andG - three hydrogen bonds - 4What do all four organic bases contain?nitrogen
- 5What is the DNA made up of?Two strands therefore it is called a double helix
- 6For each turn of the helix how many base pairs are there?10 for each complete turn
- 7What is in a nucleotide-phosphate group
-deoxyribose (pentose) sugar
-organic bases (A,T,G and C) - 8How are the deoxyribose sugar, organic base and phosphate group joined?Using a condensation reaction.
- 9What is the name given to a single nucleotide?mononucleotide
