DNA mutations that change DNA sequence occur during: 1) replication O2) transcription 3) translation 4) protein synthesis A person has an adrenal tumor with increased secretion of aldosterone. They might develop secondary hypertension with an: 1) increase in potassium and blood volume O2) decrease in potassium and blood volume 3) increase in potassium and decrease in blood volume O4) decrease in potassium and increase in blood volume

Which of the following statements about mutations is/are incorrect? Choose all that apply. O Mutations in RNA during transcription are not inherited by daughter cells over multiple generations. O Mutations arise from sources other than just mistakes made during DNA replication. O Germ-line mutations can be passed down to offspring. O DNA replication machinery generates errors at a lower rate than RNA transcription machinery. O Mistakes in DNA replication do not lead to heritable mutations. Somatic mutations are often passed...

Choose the best answer I) All of these events occur during the transcription in eukaryotes EXCEPT a) Messenger RNAs undergo extensive processing. b) A single mRNA codes for several proteins. c) Transcription and translation occur in separate cellular compartments. d) Unwinding from histones is probably necessary for transcriptional activation of the DNA. 2) Prokaryotic and eukaryotic promoters: a) contain AT-rich regions. b) interact with transcription factors. c) are influenced by base sequences thousands of base pairs away, which increase their...

Predicting Mutations. One of the most interesting applications of transcription and translation is understanding genetic mutations. Let's give it a try! What do you predict will happen if a mutation changes a codon from UCA to UCC? Will this person be affected? Why or why not? What do you predict will happen if a mutation changes a codon from UAC to UAG? Will this person be affected? Why or why not?

How do transcription factors affect gene expression? a.) They are molecules that can turn genes on or off. b.) They are mRNAs that contain extra information that is not part of the DNA genome. c.)They modify the chromosome structure to create mutations. d.) They are signals that tell cells whether to divide or not.

In the lac operon, what are the likely effects on operon transcription of the mutations listed below? PLEASE EXPLAIN your answers. I think I answered the first part of the question but need help explaining why. Mutation of the consensus sequence in the lac promoter. i. Transcription is blocked. Mutation of the repressor binding sites in the operator sequences. i. Transcription is constitutive. Mutation of the lacI gene affecting the allosteric site of the protein. i. Transcription is blocked. Mutation...

In an essay of between 100-150 words, explain the events that occur during transcription initiation in prokaryotes. You may wish to include the structure of a gene promoter in your summary. You must be thorough enough to use up 100-150 words, but not too verbose to go beyond that word limit.
