8. Two substitution mutations are shown below; each changes an mRNA codon for an enzyme: UUA changes to AUA GAU changes to GUU One substitution has little effect on the biological activity of the enzyme, while the other is highly damaging. Predict which mutation will cause more damage, and justify your answer.

Question 39- ( PLEASE show your work and explain your answer so I understand going forward.) What is the sequence of bases in mRNA produced from a section of the template strand of DNA that has the following sequence of bases? — G — A— T— T — C—A —

What is the length, in nm, of a linear fragment of a double-stranded DNA composed of 855 bp and in B-form?

Select all the TRUE statements related to stability of nucleic acids. Single-stranded RNA is stabilized by base pairing that can occur between different segments of the sequence DNA fidelity is critical because DNA structure is maintained long-term in a cell Errors in mRNA sequence can be tolerated because each molecule is used for a short time and then degraded Any mutation in DNA sequence will result in a completely disrupted protein structure Both rRNA and tRNA and more stable than mRNA because they serve structural roles over a longer time frame One each new copy of the DNA genome is produced, the old DNA strands are degraded

1. Draw the two Watson-Crick Bases Pairs and show how G- C and A-T recognize each other by hydrogen bonding. 2. Draw the full structure of two nucleotides - one from DNA and one from RNA. Point out the key difference between the two. 3. Write out an example of a condensation reaction forming a phosphate-sugar bond. 4. Write out an example of a condensation reaction between a nucleic acid base and a sugar. 5. State the "Central Dogma" of biochemistry.

Deoxyadenosine monophosphate (dAMP) and guanosine monophosphate (GMP) are nucleotides. The similarities between dAMP and GMP are that they both have? -an alpha (central) carbon.-the same R group.-a phosphate group.-a pentose (5 sided) sugar-an amino group-a nitrogenous base.
