The ability of Bacteria and Archaea to adapt to new environments as a part of bacterial evolution, most frequently results from the acquisition of new genes through horizontal gene transfer rather than by the alteration of gene functions through mutations. Resistant gene can be transferred from one bacterium to the other. Created by. The Horizontal gene transfer actually occurs through transformation, transduction, conjugation and other gene transfer agents in bacteria. This test is Rated positive by 93% students preparing for IIT JAM.This MCQ test is related to IIT JAM syllabus, prepared by IIT JAM teachers. Transfer of genes (gene flow) in between different species is known as (a) Vertical gene flow (b) Horizontal gene flow (c) Lateral gene flow (d) Side gene flow 15. Chapter 01. Scientists can use vertical gene transfer, which is more like sexual reproduction in humans. The transmission of resistant genes occurs via vertical gene transfer or horizontal gene transfer. Multiple Choice Questions on Population Genetics - … a) Transformation. This is the mechanism of antibiotic resistance in bacteria. MICROBIAL GENETICS Multiple Choice Questions :-1. 15.

A gene fusion construction for carrying this work will A. have Px but not the rest of the X coding region B. have the promoter of lacZ or some other reporter gene C. allow to monitor the expression of all genes with a promoter similar in sequence to Px transcription. a. vertical gene transfer: transfer of DNA from parent to offspring during normal cell division horizontal gene transfer is transfer of DNA between genomes; very common in bacteria. DNA imbibition by cells/tissues/organs. Direct gene transfer can be categorized into two main groups: physical gene transfer and chemical gene transfer. The foreign DNA is either randomly inserted into the host genome or recombines if there is sequence homology between the two genomes. Due to Horizontal Gene Transfer; Due to Vertical Gene Transfer; Choose the correct option: [A] Only 1 [B] Only 1 & 2 [C] Only 2 & 3 [D] 1, 2 & 3. Which of the following is … Multiple Choice . STUDY. Write. The lesson will be delivered in English and the notes for the same will be provided in English. It is most often thought of as a sexual process that requires a mechanism for the mobilization of chromosomal DNA among bacterial cells. In this session, Dr. Muskan Chaudhary will be discussing the topic Horizontal Gene Transfer in Bacteria. C) complicates the construction of phylogenetic trees and the interpretation of specific traits in relation to … 7. 1. Basic medical genetics for AIPGEE, FMGE, PGIEE, MCCEE Want to make best use of you time? Horizontal gene transfer research often focuses on prokaryotes because of the abundant sequence data from diverse lineages, and because it is assumed not to play a significant role in eukaryotes. Vertical gene transfer. Because the resistance genes very often lie on transmissible gene sections, they can also be exchanged between bacteria of the same type or of different types (so-called horizontal gene transfer). 3. A. there has been little change in either genome B. E. coli has acquired many genes via horizontal transfer C. E, coli has lost approximately 50% of … Drug resistance genes are often carried on plasmids or in transposons that can undergo vertical transfer easily and between microbes through horizontal gene transfer. Horizontal gene transfer is able to cause rather large-scale changes in a bacterial genome. 14. via horizontal transfer C. E, coli has lost approximately 50% of its genome D. none of these. dynamic processes involved in the plant health. The unidirectional transfer of genetic material from a donor bacterium to recipient bacterium by cell to cell contact is termed as. B) occurs within bacterial species. Flashcards.
