Structure of RNA and DNA
- James Watson and Francis Crick 1953
- They worked out the structure of DNA -
following the pioneering work of Rosalind Franklin.
- DNA is made out of
two strands of
necleotides
- Each of the two
strands are
extremely long
- They are joined together by
hydrogen bonds, which are
formed between certain bases
- They worked out the structure of DNA -
following the pioneering work of Rosalind Franklin.
- A pentose sugar, phosphate group and organic
base are joined as a result of a condensation
reaction
- The pentose sugar is deoxyribose
- The pentose sugar is deoxyribose
- In DNA the sugar is deoxyribose, whereas in
RNA the sugar is ribose
- Individual necleotides are made up of:
- A Pentose group
- A phosphate group
- A nitrogen containing organic
base
- Cytosine, C
- Guanine, G
- Double
hydrogen bond
- Double
hydrogen bond
- Guanine, G
- Adenine, A
- Thymine, T
- Triple hydrogen
bond
- Triple hydrogen
bond
- Thymine, T
- Cytosine, C
- A nitrogen containing organic
base
- A phosphate group
- A Pentose group
- DNA strands carry immense amounts of genetic information
- Base pairings lead to DNA being
able to replicate
- Thymine
- Uracil
- Cytosine
- Are all Purine bases
- Are all Purine bases
- Cytosine
- Uracil
- Adenine
- Guanine
- All Pyrimidine bases
- All Pyrimidine bases
- Guanine
