Answer:
B) Helicase uses energy from ATP Hydrolysis
Explanation:
Helicase's primary function is to separate the annealed nucleic acid strands. It is a motor protein and moves directionally along the phosphodiester backbone. It usually separates strands of double helix DNA or self annealed RNA. It used the energy from ATP hydrolysis and breaks hydrogen bonds between nucleotide bases.
In human body 95 types of helicases are found. They have sequence motifs required for ATP binding, ATP hydrolysis and translocation along nucleic acid phosphodiester backbone. The variable portion in their amino acid sequence imparts specific feature to each helicase.
Sources of heat from inside earth is radioactive decay and residual heat.
We can reduce air pollution by using public transport instead of private vehicles when possible, this can reduce the gas released from private cars. We can reduce energy consumption by setting air conditioner to a suitable temperature such as 26°C or use fan instead. Also make sure we turn off all the electrical appliances when we leave a place.
During early civilization, the main source of fresh water was from a river. Nowadays, we have reservoirs and lakes to get fresh water. <span />
