Various strains of bacteria are able to transfer genes to eukaryotic hosts. This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. Which of the following is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells? A - Bacteria and Eukarya have similar mechanisms for the formation and use of enzymes in metabolic processes. B - Bacteria and Eukarya use the same enzymes in all of their metabolic processes so the genes are interchangeable. C - Bacteria and Eukarya share similar reproductive mechanisms so the cells reproduce without recognizing foreign DNA. D - Bacteria and Eukarya have the same mechanism for replicating DNA so genes can easily be transferred between the two types of cells.
In each case, these are enzymes that catalyze thesame reaction in different species. The question is: are they related or not? i.e. Are the structures essentially the same? Often you can get similar reactions from proteins thatevolved from a common ancestor (e.g., trypsin and chymotrypsin). Sometimes the samereaction can be catalyzed by proteins with very different evolutionary origins and with verydifferent structures (e.g., trypsin and subtilisin). Your job is to decide if these proteins have fundamentally different folds or if they have basically the same fold. Briefly justify your answer.1. Aminopeptidases from a mammal (PR1A) and the malaria parasite (PR1B)2. Bisphosphoglycerate mutase from a mammal (PR2A) and the toxoplasma parasite(PR2B)
why does a clone of cells produceonly one type of G-6-PD enzyme? What would you expect to happen if a clone was derived from an early embryonic cell? Whydoes the initial sample of tissue produce both forms of G-6-PD?
A scientist observing a cell during gene expression would be able to easily distinguish it as a prokaryotic cell by which of the following observations? Group of answer choices as soon as the DNA introns are removed from the template after the 5' caps are converted to mRNA after a transcription initiation complex has been formed during transcription once the pre-mRNA has been converted to mRNA 2. Which of the following would best ensure that a kidney cell and a liver cell from the same person would express different genes? Group of answer choices differences in introns unique sets of transcription factors they only have specific genes unique sets of promoters
. In two isolates (one is resistant to ampicillin and theother is sensitive to ampicillin) of a new bacterium,you found that genes encoding ampicillin resistanceare being transferred into the sensitive strain. . To determine if the gene transfer is transformationor transduction, you treat the mixed culture of cellswith DNase. Why would this treatment distinguishbetween these two modes of gene transfer? Describethe results predicted if the gene transfer is transformation versus transduction
suppose that a gene has a mutation that changes one nucleotide. Because of this one nucleotide change, the mRNA produced from this gene has a slightly difference sequence compared to the mRNA produced from the unaltered/non-mutated gene. However, the resulting protein produced from both of these gene versions is exactly the same. This type of mutation would be classified as
Researchers produced transgenic corn that contained an extra codon for phenylalanine andhad a high oil content. Suppose an existing commercial variety of corn was modified in thesame way and sold to farmers. Would you consider this variety to be a genetically modifiedorganism ? Should the corn produced by this variety be labeled as agenetically modified food product?
In the experiment of Figure shown , a met− bio− thr+ leu+ thi+ cellcould become met+ bio+ thr+ leu+ thi+ by a (rare) double mutationthat converts the met− bio− genes into met+ bio+. Likewise, a met+bio+ thr− leu− thi− cell could become met+ bio+ thr+ leu+ thi+ bythree mutations that convert the thr− leu− thi− genes into thr+ leu+thi+. From the results of Figure shown, how do you know that the occurrenceof 10 met+ bio+ thr+ leu+ thi+ colonies is not due to thesetypes of rare double or triple mutations?

Group of answer choices as soon as the DNA introns are removed from the template after the 5' caps are converted to mRNA after a transcription initiation complex has been formed during transcription once the pre-mRNA has been converted to mRNA 2. A scientist working in an IVF (in vitro fertilization) clinic mistakenly produced a human zygote with 45 chromosomes. What biological process could explain how this happened? Group of answer choices failure of an egg to complete meiosis II failure of the egg nucleus to be fertilized by the sperm a non-disjunction in meiotic anaphase occurring in either an egg or sperm incomplete cytokinesis during spermatogenesis after meiosis I
Suppose that a gene has a mutation that changes one nucleotide. Compared to the protein produced from the non-mutated gene, the protein produced from this mutated gene has one different amino acid. This newly altered protein provides enhanced resistance to tetracycline (an antibiotic). This type of mutation would be classified as a
Why is it adaptive for a bacterium to not express the genes that encode that lactose utilization proteins when lactose is not available? a. Catabolism of lactose in protein transcription needs a lot of energy. b. The bacterium opts not to express the genes that encode proteins responsible for breaking down lactose to conserve enzymes. c. The bacterium opts not to express the genes that encode proteins responsible for breaking down lactose to conserve energy. d. The reason is conservation of energy for the enzyme. e. The bacterium opts not to express the genes that encode proteins responsible for breaking down lactose to conserve lactose.
