a) What is a mutation in molecular terms? b) a mutation deletes a base in the genomic DNA discuss how that will affect the reading frame and expression product production.
Using the following list of codons describe, using diagrams etc., how information stored in
the DNA is translated into a peptide. Be sure to discuss all steps. In other words, use a diagram and give me sequences, transcription and translation steps. Show the sequences of the sense and the other DNA strand, the mRNA and the tRNA’s.
UUU -phenylalanine UCU -serine AUG –initiation/methionine
CUU -leucine ACU -threonine
GUU -valine UAA -Termination
Microbiologists describe the processes of transcription and translation as “coupled” in bacteria. This term indicates that bacterial mRNA can be undergoing transcription at the same moment it is also undergoing translation.
How is coupling possible in bacteria?
Is coupling of transcription and translation possible in single-celled eukaryotes, such as yeast? Why or why not?

- Which of the following mutations in the protein-coding region of a gene is more likely to lead to complete loss of function of the encoded protein: an insertion of six nucleotides or a deletion of two nucleotides? Briefly explain your answer.arrow_forwardGenes can be transcribed into mRNA, in the case of protein coding genes, or into RNA, in the case of genes such as those that encode ribosomal or transfer RNAs. Define a gene. For the following characteristics, state whether they apply to (a) continuous, (b) simple, or (c) complex transcription units.i. Found in eukaryotesii. Contain intronsiii.

How does transcription and translation differ in prokaryotes vs. eukaryotes (i.e. What is present in one but not the other)? 2.) What it means when we say that genetic code is redundant? 3.)

- The following double stranded segment of DNA is part of a protein coding gene. The segments in uppercase letters (ACTG) represent the exons. The segments in lowercase letters (acgt) represent introns. The lower strand is the template strand that is used by the RNA polymerase to make an RNA transcript.

Along the way, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations given in the chapter, what answers would you propose to the following fundamental questions: Question: How do we know that the initial transcript of a eukaryotic gene contains noncoding sequences that must be removed before accurate translation into proteins can occur?arrow_forwardThe following fictitious double-stranded bacterial DNA sequence codes for a fictitious protein. Both strands are shown; the top strand reads 5' to 3' left to right, while the bottom strand reads 5' to 3' right to left. Transcription begins with and includes the red underlined A/T (top strand/bottom strand) base pair.

Would this mutation affect the process of transcription? Would this mutation affect the process of translation? Explain your reasoning.arrow_forwardThe design of antibiotics requires that the drug prevents the growth of bacteria without compromising cellular functions in humans. I’d like you to think of the differences in the process of gene expression in prokaryote and eukaryotes and suggest two possible targets for the design of an antibiotic. Explain what processes you are preventing (although we have only discussed transcription and translation, you can include replication if you’re familiar with this process) and how your drug would be targeted to affect prokaryotes only.arrow_forwardFor a specific type of mutation at a given location in a particular gene, identify whether it will affect the size of the mRNA, the protein, or both.
