The Doppler Effect is also known as red shift. Red shift shows the distance of galaxies. The redder the shift then the further away the galaxy, however the bluer the galaxy then the closer it is. Red Shift shows that the universe is continuously expanding. <span />
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.

Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules. Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule
