Answer:
In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.
Explanation:
The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.
Answer
Water molecules sticking to a mirror’s surface is an example of adhesion.
Explanation
Adhesion is the property of attractive force that exist between two different molecules. water molecules adhere to other surfaces due to their polar nature.
Importance
it is because of adhesive forces that water can travel and cover a distance of 100 meter up in the plants through xylem vessels as recorded in the world tallest tree (red wood tree)
