Microbial Recombination and Gene Transfer
The type of recombination that commonly occurs between a pair of homologous DNA sequences is,
a bacteriophage transfers bacterial DNA
bacteria take up double stranded DNA from the environment
DNA-degrading enzymes in the extracellular medium would stop the process
a bacteriophage genome is integrated into the bacterial genome
Which of the following type of recombination does not require homologous sequences and is utilized by mobile genetic elements that move about chromosomes?
F factor plasmids play a major role in
Who discovered transposons (jumping genes)?
Recombination of virus genomes occurs
simultaneous infection of a host cell by two viruses with homologous chromosomes
