Answer:
Explanation:
Enzyme are protein molecules that catalyzes chemical reaction.
In DNA replication, enzymes play a major role.
Enzymes identify the starting point of replication, attach itself and then unwind the Deoxyribonucleotide acid DNA Strand to form the replication fork.
Enzyme Helicase unwind and breaks the hydrogen bond between the base pair, opening up the helix structure to form a template for the new strand.
DNA polymerase also play a major role, it synthesis new DNA by adding primer to the DNA sequence for replication to occur, they also proof read the copy of DNA Strand being made to avoid errors during replication and add nucleotide to the growing DNA strand.
Answer: Heat produced from the electric ice cream maker killed the grass
Explanation:
The principle behind refrigeration of the ice cream maker is that
- air from the atmosphere is collected into the condenser,
- it is mixed with refrigerant gases like liquid nitrogen
- then it becomes cool, and freezes the prepared cream to become iced
- then, the HEAT generated during this conversion is ejected from the electric ice cream maker in form of hot air.
This hot air directed towards the grass will kill its living cells, thus it turns yellow over time
