		Polysomes
		Spliceosomes

Expert Solution

Bacteria can simultaneously transcribe and translate gene through the formation of polysomes ( 3rd option )

polysomes or polyribosomes are a group of ribosomes or cluster of multiple ribosomes bound to a mRNA ( appears as a bead on a string ) and act to translate polypeptide according to mRNA , during translation . and it is formed during elongation phase of transcription . therefore in bacteria cell polysomes helps transcription and translation simultaneously . hence it is the right option .

1st option is wrong . as trypanosomes ( Trypanosoma sp . ) are unicellular parasitic protozoa that causes sleeping sickness diseases (trypanosomiasis ) . it is carried by tsetse fly . and trypanosomes infects mainly mammals . there is no link between trypanosomes and bacterial transcription and translation .

2nd option is also wrong . proteosomes are protein complex that degrade damaged or misfolded protein or unnecessary protein by proteolysis ( methods in which protein breaks down to peptide or amino acids ,) proteosomes are found inside all eukaryotes , archea and some bacteria . proteosomes are not related with transcription and translation , hence proteosome is wrong option .

4th option is wrong . as spliciosome is complex structure / machinary made of snRNA , proteins primarily found in the nucleus of eukaryotic cells ( not in bacteria cell ) and responsible for splicing mechanism ( removes intron from pre mRNA i.e it is involved in RNA editing not transcription or translation ). hence it not correct option .

Transcribe and translate the genes shown below. Assume that transcription starts five bases past the TATAAA box and ends five baes past the Poly-A site. Label the ends of all DNA and RNA strands. TATA box is on the NON-TEMPLATE (coding) strand. Poly A site= AATAAA is also on the NON-TEMPLATE (coding) strand. 1. 3’GGGCATTGGATATTTCGCCAAAGGGGGGTATACCCCAAACCGGCACCCGCATTGCAGGAGAGAATTCGTCCGGTTATTTCGGCG5’ 5’CCCGTAACCTATAAAGCGGTTTCCCCCCATATGGGGTTTGGCCGTGGGCGTAACGTCCTCTCTTAAGCAGGCCAATAAAGCCGC3’ 2. 3’AATGCAAATAAGGATGGGGAGCAGCCTAGACCCCAAACCGGCATTGTATCGTCCGGCTCGGTTTAAATATCGGC5’ 5’TTACGTTTATTCCTACCCCTCGTCGGATCTGGGGTTTGGCCGTAACATAGCAGGCCGAGCCAAATTTATAGCCG3’

a) Describe two different mechanisms by which bacteria can simultaneously acquire resistance to multiple antibiotics of different classes. b) New point-of-care molecular tests are appearing that will rapidly distinguish between bacterial and viral infections, and in most cases identify the strain if it is bacterial. How will these tests improve antibiotic stewardship? (give an example if you can think of one) d) Metronidazole acts by making breaks in DNA strands. DNA breaks are mutagenic, and most mutagens are potential carcinogens. Why...

QUESTION 12 For the lac operon to actively transcribe its genes, which of the following must happen? a. The absence of glucose leads to cAMP production, which binds to CAP, which then binds to the CAP site of the operon. Also, the presence of lactose leads to allolactose production, which binds to the lac repressor, preventing it from binding to the operator. RNA polymerase then binds to the promoter. b. The presence of glucose leads to cAMP production, which binds...
