2 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

11 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

12 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

13 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

14 The ukaryotic Supremacy 500 pts 5 Insert Question ere Which of the following amino acid sequences is specified by the NA sequence below? A A gly ala lys lys ala ser gly tyr cys trp leu phe TATT A / : gly ala lys ack

15 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

16 2 Insert Question ere Which of the following types of mutations is MOST LIKLY to A result in a non functional protein? otta Keep It Regulatin' 200 pts A silent mutation nonsense mutation missense mutation frameshift mutation / : nonsense mutation (creates a pre mature STOP codon) ack

17 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

18 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

19 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

20 iotech Knowledgey 100 pts 1 Insert Question ere Which procedure can be used to make many copies of a targeted A segment of NA? A gel electrophoresis polymerase chain reaction restriction fragment analysis single nucleotide polymorphisms / : polymerase chain reaction ack

21 iotech Knowledgey 200 pts 2 Insert Question ere This diagram shows the results of a gel electrophoresis of several fragments of NA obtained from a restriction enzyme digestion of human A NA. What can be concluded from the diagram? A The NA in wells 1 and 2 are likely from the same person. The NA in wells 1 and 3 are likely from the same person. The NA in wells 1 and 4 are likely from the same person. The NA in wells 1, 2, 3, and 4 are likely from the same person. A / : The NA in wells 1 and 2 are likely from the same person. ack

22 3 Insert Question ere The rate at which a particular NA fragment moves through a gel during electrophoresis can be affected by A all of the following XPT iotech Knowledgey 300 pts A increasing the size of the NA fragment. decreasing the voltage in the electrophoresis chamber. the original source organism from which the NA sample was drawn. increasing the density of the gel through which the fragment moves. / : the original source organism from which the NA sample was drawn. ack

23 4 Insert Question ere A iotech Knowledgey 400 pts Restriction enzymes are used in recombinant NA technology to create restriction fragments that can then be used in restriction fragment analysis to identify a mutation in the NA sequence at a particular restriction site. The analysis of restriction fragment length polymorphisms (RLPs) is most closely related to which of the following? A fighting disease NA fingerprinting polymerase chain reaction (PR) post transcriptional control of gene expression / : NA fingerprinting ack

24 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
