Question

Question 6 1 pts A transversion occurs in the coding DNA triplet UAU for Tyr in the middle of the gene sequence and mutates to UAA. What would you expect during translation? Translation would stop prematurely. Tyr would still be coded for. Tyr would be substituted with Ser. There would be a shift in the open reading frame, changing all amino acids from the point of mutation. Question 7 0.5 pts The codon AUG has two purposes: 1) Indicating the start of protein synthesis and 2) coding for the amino acid of Methionine. True False

Question 7 1 pts True or false: Stop codons code for an amino acid in a protein sequence during translation true false Question 8 1 pts Which of the following is a difference in how transcription & translation operate in prokaryotes vs. eukaryotes? In prokaryotes, transcription & translation occur simultaneously. In eukaryotes, transcription is completed & the mRNA is transported out of the nucleus before translation begins. In eukaryotes, transcription & translation occur simultaneously. In prokaryotes, transcription is completed & the mRNA is transported out of the nucleus before translation begins. In prokaryotes, translation is carried out by ribosomes. In eukaryotes, translation is carried out by tRNA. Eukaryotes have two stop codons. Prokaryotes have three stop codons.

Which of the following would result in translation not beginning? a mutation in one of the stop codons a mutation so that there is no AUG codon a very short poly A tail a mutation in the promoter 2. Which of the following is NOT true of an anticodon? it is comprised of three bases it is a sequence of three nucleotides it is critical for ensuring that the correct amino acid is added to a growing chain it is part of the molecular structure of mRNA 3. What would you expect would be the outcome of a DNA mutation within the enhancer region of a eukaryotic gene? the gene would have a frameshift mutation regulatory transcription factors would not activate transcription transcription of that gene would not occur due to RNA polymerase not binding to the promoter the gene would get over-expressed (too many copies of RNA would be made)

00:01 Let's look at the question number seven first.
00:03 True or false.
00:04 Stop codon calls for an amino acid in protein sequence during translation.
00:09 Now, there are 64 codons for 20 common amino acid.
00:12 And out of the 64 codons, there are three codounds that do not call for any amino acid.
00:18 They are uaa, uga, and uag.
00:22 And these three codows are stock codons.
00:24 They are the termination signal for the synthesis of polypeptide.
00:30 So which means when the rhazone slide through the mrna and when it finds the stop codon, it will separate and stop the translation.
00:41 So that means the three stop codon do not give you any amino acid.
00:46 So the answer here is false because it doesn't give you any amino acid.
00:52 Question number eight, which of the following is a difference in how transcription and translation operates in 2 kary, new karyotes? let's look at a difference on the right side of the screen.
01:03 Prokaryotes are primitive, so they do not have a nucleus.
01:08 And so in precarriots, transcription and translation are up or are happening simultaneously.
01:17 That means the transcription is happening.
01:20 While before the transcription is done, the translation starts on the growing mri chain.
01:27 So they happen at the same time...
