Chapter 21, Problem 1Q

Antibiotics such as ampicillin are inactivated by heating above 65°C. Your friend is working in a lab in which a student preparing agar plates for growing bacteria adds ampicillin before allowing the sterilized agar to cool below 65°C. Your friend performs a cloning experiment using plates made from this agar before the mistake is realized. What do you predict your friend’s plates will look like?

Expert Solution & Answer
Check Mark
Summary Introduction

To determine: The look of the plates after the cloning experiment using the plates with sterilized agar. The plates consist of the inactivated ampicillin as it is added to the agar before cooling below 65ºC.

Introduction: The enzymes and bioactive compounds are sensitive to temperature. The activity of these enzymes or proteins is limited within a limited temperature change. The increase in the temperature beyond its denaturation point deactivates the enzyme.

Explanation of Solution

The addition of the ampicillin to the plates should occur below 65ºC. However, ampicillin has been added above 65ºC. Hence, it would be deactivated.

The ampicillin was being added to the agar medium to grow the strains of microbes which are ampicillin resistant. This mistake would lead to the growth of the mixed microbial strains which would consist of both ampicillin resistant strains as well as nonresistant strains.

Hence, both ampicillin resistant and nonampicillin resistant strains of microbes will appear in the colonies formed on the plates.

Molecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA? Thank you
Molecular Biology Question Explain why the cell doesn’t need 61 tRNAs (one for each codon). Please help. Thank you
Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this.     Please help. Thank you
