Answer:
Geothermal and Nuclear
Explanation:
Geothermal is the most reliable renewable energies and comes from the Earth. Nuclear energy is actually non-renewable but it is safe and extremely effecient.
The plants will die due to lack of nutrient, causing the smaller animals who feed on plants to starve. The large animals who eat the smaller animals will die off as all there prey (the smaller animals) are dead. Google 'Food Chains' and 'Food Webs' for some in depth explanations.
Answer:
The enzyme Topoisomerase functions to prevent super-coiling of the DNA molecule during replication.
Explanation:
- During replication, topoisomerases are required to relieve the positive supercoiling that arises from DNA unwiding mediated by Helicases.
- A DNA topoisomerase is a nuclease that breaks a phosphodiester bond in a DNA strand.
- All topoiomereases are classified as Topoisomerase I and Topoisomerase II depending on whether they cleave one or two strands respectively.
- Topoisomerase I do not use ATP as a source of energy, the reaction is powered by energy stored in super-coiled DNA.
- Topoisomerase II also do not require external energy but it utilizes ATP hydrolysis to drive conformation changes in the protein during reaction cycle.
