JOPARY! Unit 6 xam Review ame January 29 th, 2019
ow to play JOPARY! The class will be split into two teams, the R team and the RN team. When a question is displayed, the R team will use the A keys on their clickers to answer. The RN team will use the keys to answer. The team with the IST PRNTA of correct responses will earn the points for that question, AN the right to pick the next category! Let's do a practice question to make sure everybody understands how to play. o on to the Practice Question

The ukaryotic Supremacy 100 pts 1 Insert Question ere The famous experiment performed by Meselson and Stahl demonstrated that NA replication was a "semiconservative" A process. "Semiconservative" NA replication results in two new NA molecules / : each with one new strand and one original strand A each with one strand. each with two new strands. each with two original strands. each with one new strand and one original strand. ack
The ukaryotic Supremacy 200 pts 2 Insert Question ere New NA and RNA molecules can only be assembled in the 5' to 3' direction. This is because polymerase enzymes can only A move along the template NA strand in the direction. A 1' to 5' 5' to 3' 3' to 5' 5' to 1' / : 3' to 5' ack
The ukaryotic Supremacy 300 pts 3 Insert Question ere When the ribosome reaches a stop codon, the release factor A attaches at the ribosome's site. A "A" "" "P" "S" A / : "A" (stands for amino acid next one to be added) ack
The ukaryotic Supremacy 400 pts 4 Insert Question ere In the process of eukaryotic protein synthesis, there are 3 NA nucleotides needed to specify a single amino acid. owever, a transcription unit is often A significantly longer than three times the number of amino acids of the resulting polypeptide. This is because RNA processing removes and splices together. A introns... exons uracils... thymines polypeptides... proteins RNA primers... Okazaki fragments A / : introns... exons ack

1 Insert Question ere otta Keep It Regulatin' 100 pts The inheritance of traits transmitted by mechanisms not directly involving the nucleotide sequence is called "epigenetics." or instance, although these mice share identical NA, they have distinct coat colors and body compositions. Typically, A this occurs when environmental factors affect chromatin structure. Alterations to the structure of chromatin primarily affect A NA sequence. gene expression. RNA processing. mrna degradation. / : gene expression ack

3 Insert Question ere The expression of genes in eukaryotes usually involves factors A that can affect all of the following XPT otta Keep It Regulatin' 300 pts A mrna degradation. protein degradation. enzyme modification of chromatin. deletion of genes in some cell types but not in others. / : deletion of genes in some cell types but not in others. ack
4 Insert Question ere otta Keep It Regulatin' 400 pts In this illustration of the various mechanisms of gene regulation, which is NOT categorized as a post transcriptional control mechanism? A A / / / / A / ack
otta Keep It Regulatin' 500 pts 5 Insert Question ere Which of the following is LAST likely to increase the rate A of transcription of a particular segment of NA? A the acetylation of histones the methylation of NA nucleotides the conversion of heterochromatin to euchromatin the binding of activator proteins to enhancer regions of NA / : the methylation of NA nucleotides ack

5 Insert Question ere iotech Knowledgey 500 pts Plasmid vectors can be used to insert human genes into bacteria so that they produce human proteins. In general, however, it is not possible to directly insert A a eukaryotic gene into a bacterium and get it to express the desired eukaryotic protein. Why? A acteria do not undergo translation. acteria do not undergo transcription. acteria do not undergo RNA processing. acteria use a different genetic code than humans. / : acteria do not undergo RNA processing. ack
