What is the role of dna helicase during dna replication? to unwind the duplex dna to attach primers to the replicating strands to add bases in the sugar-phosphate backbone nextreset

To unwind the duplex DNA.

Explanation:

DNA helicases are a type of enzymes that play an important role in unwinding double-stranded DNA during the process of DNA replication.

These enzymes use the energy from ATP hydrolysis to perform their function.

By causing the separation of the double-stranded DNA, the DNA helicases make the single-stranded DNA available for the DNA polymerases to start adding the complementary nucleotides.

im not intirely sure but i think the anwser is d relative humidity

carbon traps heat so more of it makes it hotter causing global warming. during the ice age carbon levels in the atmosphere were low so it got very cold. so the common things between them is carbon levels in the atmosphere.
