The genetic fingerprint is differentiated based on the differing lengths of short tandem repeats (STRs) between genes. Everyone has different lengths of STRs so when their DNA is hydrolysed by restriction...

Water molecules are dipolar - they have both positively charged and negatively charged regions due to differences in the electronegativity of atoms (this is how strongly they attract electrons). This prop...

DNA Helicase unwinds double helix by breaking hydrogen bonds where the gene is located.The single stranded part of the helix will act as template strand for RNA.Free floating nucleotides will attach to co...

Prior to the formation to any ecosystem, the area can be defined as barren and without the ability to support large species flora or fauna. For an ecosystem to form the area must first be made habitable, ...

1. The first step is the area of DNA to be replicated is 'unzipped' by DNA helicase. 2) The separation of the two strands forms a replication fork. 3) The strand that is oriented in the 3' to 5' direct...
