Describe the structure of DNA as repeated units of nucleotides that consist of nitrogenous bases, sugar and phosphate.

Show a polynucleotide chain of DNA?

describe specifically how protein tertiary structure facilitates DNA replication.

Describe the structure of an RNA nucleotide while pointing out the various differences between RNA and DNA (structural and functional differences).

Dna is composed of a phosphate back bone, a sugar and four nitrogenous bases. Of the following bases: adenine, cytosine,  guanine, and thymine; which are the hydrogen bond donors and which are the acceptors?

What occurs when a base at a certain position in one strand of the DNA molecules is replaced by one of the other three bases?

Give six points of difference between DNA and RNA in their structure/chemistry and function.

Draw & label a simplified diagram of a DNA nucleotide:

Determine the effect of the following mutations on the DNA sequence. In each case, the mutation is described after the sequence. Guanine nucleotide (G shown in red in the DNA sequence below) was substituted by C Write out the sequence of the mutated DNA and the protein made from it. What is the effect of this mutation on the protein? (For example, how will the mutation affect the length and sequence of the protein?  What about the function of the protein?)
