What else can I help you with?
Which step happens first in DNA replications?
The first thing that happens is a replication structure binds to the DNA molecule. This is usually a signalling molecule or some type of protein. Next, this replication structure attracts DNA helicase enzymes which "unzip" the double stranded helix.
Where does Helicase attach to on the DNA strand?
Helicase attaches to the DNA strand at the replication fork, which is the region where the double-stranded DNA is unwound to separate the two strands during DNA replication. Helicase helps to unzip the double helix by breaking hydrogen bonds between the base pairs.
During transcription what molecule opens the DNA?
During transcription, the enzyme RNA polymerase opens the DNA double helix to expose a segment of the DNA that will be transcribed into RNA.
Does DNA helicase unzip the DNA molecule during DNA replication?
Yes, DNA helicase is an essential enzyme that unzips the DNA molecule during DNA replication. It unwinds the double helix structure by breaking the hydrogen bonds between the complementary base pairs, separating the two strands of DNA. This process creates a replication fork, allowing other enzymes, like DNA polymerase, to synthesize new strands based on the original templates.
DNA replication that unzip the DNA strand is?
DNA replication is a process where the double-stranded DNA molecule is unwound, or unzipped, by enzymes called helicases. This unwinding allows for the separation of the two parental DNA strands, which then serve as templates for the synthesis of new DNA strands.
What enzyme separates the DNA rails during replication?
The protein uncoils the helix and "unzip" the bases
How did Watson and crick come up with a hypothesize of DNA replication?
They predicted that the DNA double helix would unzip and replicate semiconservatively.

How can you compare DNA to a zipper?
DNA can be compared to a zipper because just like how the teeth of a zipper interlock to hold two sides together, DNA's complementary base pairs (adenine-thymine, guanine-cytosine) bond together to form a double helix structure. This bond between the base pairs enables DNA to store and transmit genetic information.
What type of bonds form between two nitrogenous bases?
Hydrogen bonds form between two nitrogenous bases. These bonds are relatively weak compared to covalent bonds, allowing the DNA double helix to unzip during processes like replication and transcription.

What is the structure and function of DNA Include DNA replication?
DNA controls the formation of cells in your body, the products they release and everything they do, as well as the process of protein synthesis. DNA is found in the cells nucleus (the control center of the cell) in the chromosomes (which are composed of DNA strands). DNA is in a shape like a coiled ladder (a double helix), the sides of the "ladder" are made up of alternating subunits of sugars and phosphates and the "ladder rings" are pairs of nitrogen bases, adenine and thymine, guanine and cytosine. The sequence of these bases forms a code, which controls the production of proteins in the cell. A section of the DNA that codes for a specific protein is called a gene. The Double Helix structure of DNA allows it to replicate easily due to the weak hydrogen bonds that unzip quickly. The structure allows allot of information to be stored in small space as the double helix curves.
How do you unzip a file programmatically in C programming?
The simplest method is to invoke a third-party unzip program via a system call. If you don't know if the required unzip program will be available on the target machine, you will need to licence an open source unzip library such as 7zip. This will allow you to unzip without making a system call.
What is the function of helicase?
DNA helicase "unzip," or separate, a strand of DNA at positions called origins. This means that the hydrogen bonds between complementary base pairs are removed (DNA is double stranded!). When they separate double-stranded DNA into single strands, it allows each strand to be copied (replication). DNA helicases use the energy stored in a molecule called ATP to break the bonds, which serves as the energy currency of cells.
