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...

Prokaryotic cells:-contain naked DNA-contain 70S ribosomes-Are much smaller than eukaryotic cellsEukaryotic cells:-Have compartmentalisation-Contain mitochondria / chloroplasts-Contain 80s ribosomesSimila...

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...

Adaptations can be split into three categories: behavioural, physiological, and anatomical.
Behavioural adaptations are those that change the way an organism acts, such as how it int...
