Section $3.$ Complete the following Table, assuming that the DNA is written with the top left being a $5\text{'}$ end and that the columns represent transcriptional and translational alignments. For DNA, use ACTG or $N$ where N represents any possible nucleotide. The RNA is drawn in the direction that it is soad from the DNA. Use the filled in table to answer the questlons on the following page. There is only one polential correct answer per question on this section.

$12.$ What makes a stop codon special?

A$.$ It is directiy bound by a tRNA. Release Fateor campleis that stops translation.

B$.$ It is directly bound by a stop IRNA that stops tramslation

C$.$ It is directly bound by a Release Factor that stops translation

D$.$ It has no corresponding URNA slalling the rthosome and allowing a IRNA$-$

Release Factor complex to stop translation

E$.$ It has no corresponding tR NA stalling the ribosome and allowing the Release Factor to stop translation

$13.$ Within this table, what does the RNA encode for as the first ammino acif towards the N end of the protein?

A$.$ CYS

B$.$ MET

C$.$PRO

E$.$ SER

$14.$ Which of the following is one of Chargaff's pules?

A$.$ All nucleotides are roughly equal because they are all equally present in the codons.

B$.$ The amount of purine $($T and A$)$ Is equal to pyrimidine $($C and G$)$

C$.$ Nucleotides are roughly random to each other because DNA is highly polymorphic

D$.$ The amount of pyrimiding $(T$ and $C)$ is equal to purine $($ A and $G).$

E$.$ None of the above

$15.$ Which row in the chart is the template strand?

A$.$ First Row

B$.$ Second Row

C$.$ Third Row

D$.$ Fourth Row

E$.$ None of the above

$16.$ What would be the effect of the mutation be if the lop strands $($per the table$)$ first Tfrom the $3\text{'}$ end was mutated to an $A.$ What would you say about that change in regards to the protelin?

A$.$ It would cause no change in the protein. also known as a slent mutation. B$.$ It would alter the amino acid incorporaled into the protein, also known as a missense mutation

C$.$ Il vould create a stop codon shuting down the protein prematurely, also known as a nonsense mutalion

D$.$ This would potentially cause a frameshift.

E$.$ None of the above
