Why does The double helix unzip in locations with lots of A-T pairs?

in the DNA the A-T pais have double H-bonds between them and G-T pairs have triple H-bonds,that's why its simpler to break two bonds instead of three bonds...so the DNA unzips from A-T pais mostly...

∙ 12y agoA and T are paired in a DNA double helix because A is a purine and so is G while T and C are pyrimidines. If two purines are put together then it is too wide. While if two pyrimidines are put together it is too narrow for the DNA strand. A and T are connected by hydrogen bonds and A can only form the proper two hydrogen bonds with T to stay with the DNA strand while Guanine forms three hydrogen bonds with C, but only C.

DNA replication that unzip the DNA strand is?
What unzips DNA strand is a particular protein called Helicase. Helicase unwinds DNA's double helix at the replication fork.
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.
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.
What is the role of DNA helicase during DNA replication?
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.
What is unzip them all?
its mean to open all the things that have zip.
DNA replication that unzip the DNA strand is?
What unzips DNA strand is a particular protein called Helicase. Helicase unwinds DNA's double helix at the replication fork.
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.
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.
How can you compare DNA to a zipper?
During the processes of DNA replication and transcription, the two strands of the DNA molecule separate, or "unzip", so that the two strands can be copied by DNA nucleotides, or the anti-sense strand of DNA can be transcribed by mRNA.

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.

How do you unzip a folder?
That depends on the archives format. Try B1 Free Archiver - it can unzip any archive.
Does anyone know where I can find a free unzip program?
You can use the free unzip program like winrar or win zip that has a trial period that you can use for free and unzip your files or make an archive for use.
What contribution did James Watson and francis crick make to science?
On February 8th, 1953 James Watson and Francis Crick were putting together a model of DNA (deoxyribosenucleic acid), but they only had enough information to make an accurate model when they saw Franklin and Wilkins picture of the X-ray. They figured out that structure; a "double helix" can "unzip" to make copies of itself, which confirmed suspicions that DNA carries life's hereditary information
What is the arrangement of nucleotides?
The arrangement of nucleotides is based on three monosaccharides. They are 5 C sugar, 4 nitrogen acids (Adaline, Thymine, Cytosine, and Guanine), and Phosphate. They two sides of the double helix shaped DNA ladder are held together loosely by hydrogen bonds. The DNA can actually "unzip" when it need to replicate. Note that the bases attached to the sides of the ladder at the sugars and not the phosphate. lol
