Match enzymes to their role in the dna replication process

1.DNA HELICASE

2.DNA POLYMERASE

3.primase

4.Topoisomerase

5.Ligase

Explanation:

1. Unwinds DNA molecule- DNA helicase

During DNA replication, DNA helicases performs the function of unwinding the DNA at origin of replication where synthesis will be initiated and it continues to unwind the DNA forming replication fork.

hence, DNA helicases unwinds DNA molecule.

2.synthesizes the complementary DNA strands- DNA polymerase

During DNA replication, enzyme performs the function of adding  nucleotides  (3')-end of a DNA strand of DNA.

hence, DNA polymerase synthesizes the complementary DNA strands.

3.synthesizes RNA primer at the initiation point- RNA primase

During DNA replication, RNA primase synthesizes a primer for replication to start as DNA polymerase binds to the primer.

hence, RNA primase synthesizes RNA primer.

4.creates nick ahead of the replication fork to relieve tension from unwinding- DNA topoisomerase

During DNA replication, DNA Topoisomerase make single-stranded breaks  in DNA to allow this process to proceed as the replication machinery  binds to unwound DNA to replicate.

hence, DNA topoisomerase creates nick ahead of the replication fork to relieve tension from unwinding.

5.joins the okazaki fragmets together- DNA ligase

During DNA replication, DNA ligase enzyme bonds single-strand break in DNA by forming a phosphodiester bond between 5′-monophosphate and 3′-OH group.

hence, DNA ligase joins the okazaki fragmets together.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
