Which steps of DNA replication are in the correct order? DNA helicase unwinds, hydrogen bonds are broken, DNA polymerase adds new strand to template, proofreading occurs proofreading occurs, DNA polymerase adds new strand to template, DNA helicase unwinds, hydrogen bonds are broken hydrogen bonds are broken, DNA helicase unwinds, proofreading occurs, DNA polymerase adds new strand to template DNA helicase unwinds, hydrogen bonds are broken, proofreading occurs, DNA polymerase adds new strand to template

Transcript

00:02 Hello, in this question we have been given steps of dna replication and we have to put them in order from beginning to end okay, so if we look closely from steps one to seven they're actually in order right so that's exactly how the procedure happens okay, let's go to the procedure so first step is halicase binds to the dna at the origin.

00:22 That's the first step definitely okay, so the step given as number one is actually the number one step so dna helicase is an enzyme which is important for the process of dna replication they bind to the strand of dna at the origin, right? next is, halikase begins to unzip the strands of dna while topoasmids keeps original strand from super coiling.

00:43 That's also the second step.

00:45 So, helicase enzyme will unwind the two strands of dna, thereby it separates the two double strands into a single -centered dna, right? so next step is single -serid binding proteins bind to dna strand to keep it from going back together.

01:01 That's exactly the third step.

01:02 Okay, single standard binding protein is a protein which will bind to both the separated strands of dna so that these two strands are kept separated hence it does not anneal the two strands, right? so the two strands were not allene together.

01:16 Right.

01:16 So this is the third step.

01:18 Then we go to the fourth step.

01:20 Fourth step is primase lays down rna primer.

01:23 So primase enzyme will synthesize short segments of rna known as primers...
