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.

A plant biologist is asked to develop strawberry plants with larger, sweeter berries. Through selective breeding, the biologist
frutty [35]

Answer: Clonal progagation

Explanation:

Clonal propagation involves the production of identical individual without the fusion of germ cells. It can be multiplication through stem and other plants part such as leaves.

Strawberry as a fruits can be multiplied using the stems thus preventing the germ cells from genetic recombination that could lead to the formation of entirely new plants. It does not involve the union of male and female germ cells.
