To map genes of a bacterial strain, conjugation must be interrupted at given times. Suppose you have Hfr cells of genotype a+b+c
OLEGan [10]

Answer:

The answer is not in any of the options and is the following:

to eliminate any remaining Hfr cells.

Explanation:

In a medium that has a streptomycin antibiotic it is used to kill Hfr donor cells after the conjugation is interrupted. This is entirely due to the streptomycin sensitivity allele (str-s) which are found in Hfr strains. The presence of the streptomycin resistance allele, located in the receptor, is used for the specific destruction of Hfr donor cells after conjugation occurs.

In STR profiling, PCR is used to obtain enough DNA to then detect the number of STRs at I specific loci.​
Licemer1 [7]

PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.

<h3>What is Short Tandem Repeat (STR) profiling?</h3>

Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.

The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.

Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.
