|
Name the three components of nucleotides: |
A pentose sugar A phosphate group A nitrogen containing organic base |
|
|
Name the five organic bases that can be found in nucleotides: |
Cytosine Thymine Uracil Adenine guanine |
|
|
How is a mononucleotide formed? |
The pentose sugar, phosphate group and organic base are joined as a result of condensation reactions to form a mono nucleotide |
|
|
How is a dinucleotide formed? |
A dinucleotide can be formed when two mononucleotides are joined in a condensation reaction between the deoxyribose sugar of one mononucleotide and the phosphate group of another The bond formed is called a phosphodiester bond Continual linking of mononucleotides form a long chain known as a polynucleotide |
|
|
Describe the structure of RNA: |
It is a single, short polynucleotide chain in which the pentose sugar is always ribose and the organic bases are adenine, guanine, cytosine and uracil |
|
|
What are the functions of RNA? |
Transferring genetic information from DNA to the ribosomes Protein synthesis |
