3) 1 of the 4 bases: Adenine, Thymine, Guanine and Cytosine - 2Name the three components of a RNA nucleotide1) Phosphate group
2) Ribose sugar
3) 1 of the 4 bases: Cytosine, Guanine, Adenine or Uracil - 3A dinucleotide is formed in what type of reaction?Condensation
- 4What bond is formed between two mononucleotides when they are joined together?Phosphodiester bond
- 5Where on the two mononucleotides does the phosphodiester bond form?Between the sugar of one mononucleotide and the phosphate group of another
- 6When lots of mononucleotides join together they form what?A polynucleotide
- 7What does DNA stand for? And what is its function?DNA = Deoxyribonucleic Acid
DNA stores genetic information. - 8What does RNA stand for? And what is its function?RNA = Ribonucleic Acid
RNA transfers genetic information from DNA to the ribosomes - 9What are ribosomes made of?RNA and proteins
- 10Name and pair up the four bases found in DNAAdenine & Thymine
Cytosine & Guanine - 11How many polynucleotide strands are there in DNA structure?2
- 12How are the strands of DNA held together?There are Hydrogen bonds between the nucleotide bases
- 13How many hydrogen bonds form between adenine and thymine?2 hydrogen bonds
- 14How many hydrogen bonds form between Cytosine and Guanine?3 Hydrogen Bonds
- 15The two strands in DNA go in opposite directions, this is known as them being ____________.Anti-parallel
- 16Describe 2 differences between the structure of DNA, and the structure of RNARNA has shorter polynucleotide chains than DNA.
RNA is single stranded, where as DNA has two anti-parallel chains.
