Match each type of E. coli strain on the left with the correct description of what happens when it conjugates with an F- strain. Dragged and dropped options on the right-hand side will be automatically saved. For keyboard navigation... SHOW MORE ✓ F-strain Hfr strain F+ strain F' strain = = ||| = F-strain becomes F+ and acquires an extra copy of some genes from the F+ strain. F-strain remains F- but some of its genes are replaced with alleles from the F+ strain. F-strain becomes F+ with no other genetic changes. Is not able to initiate conjugation but an F+ strain or one of its derivatives can conjugate with it.
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.

This question is related to the process of bacterial conjugation, which is a mechanism of horizontal gene transfer. Bacterial conjugation involves the transfer of genetic material (plasmids or chromosomal fragments) from one bacterial cell to another via a physical contact process. This exchange of genetic material can result in different outcomes depending on the type of E. coli strain involved in the conjugation process. The question asks to match each type of E. coli strain with the correct description of what happens when it conjugates with an F-strain.
