1. Construct a Venn Diagram to compare and contrast the structure and function of DNA and RNA. DNA RNA 2. The Continuity of life is based on heritable information in the form of DNA, and structure and function are correlated at all levels of biological organization. Describe how the structure of DNA is correlated with its role as the molecular basis of inheritance. (Answer must be in 3- 5 sentences only).

16. The process of attaching biological functions to DNA sequences is called?

4. Discuss and detail reasons why eukaryotic organisms appear to have more DNA than is necessary to code for all the possible proteins they have in their cells. Correlate the functions of DNA as related to proteins in your discussion. Cite specific examples. ience of Genetics society. Cit exar hiqu emplo

1. Give the different hydrolytic products of : a DNA b. RNA 2. Enumerate the biological functions of DNA and RNA.

1. In the sequence grid below, you will fill in all boxes with end polarity, nucleotide, or amino acid as described below. a. The column to the far left identifies the sequence type. Based on the nucleotides given, fill in the words "template" and "coding" (non-template) for the two DNA strands as soon as you figure out which is which. (hint: look at mRNA) b. In the second and last columns, write the polarity of the ends of each sequence (5', 3', N or C). c. The remaining columns represent transcriptional and translational alignments. Fill in all nucleotides, assuming that the template sequences in the table are read from LEFT to RIGHT d. Using the mRNA codon table provided on the next page, determine the polypeptide sequence. This sequence is from the middle of a coding sequence, therefore you do not need a start sequence. T DNA DNA mRNA codon tRNA anticodon polypeptide DNA DNA mRNA codon tRNA anticodon A C polypeptide GLY A C G e. Repeat steps 1a-1d, but now assume that the template…
