What else can I help you with?
Where DNA is unwound is called the what?
The Double Helix
What holds the DNA helicases apart?
Single-stranded DNA-binding proteins (SSBs) help hold the DNA helicases apart by coating and stabilizing the unwound single-stranded DNA. This prevents reannealing of the separated DNA strands and allows the helicase to continue separating the DNA duplex.
Are chromosome more condense than chromatin?
Yes, you can think of chromosomes tightly wound up DNA and chromatin as unwound DNA.
How does DNA replicate itself when cells divide?
The DNA double helix is unwound and each strand acts as a template for a new double helix.
Would most likely happen if DNA polymerize were not functioning properly during DNA replication?
as helicase unwinds the double stranded DNA DNA polymerase is responsible for inserting the new coresponding nucleotides during replication and wihtout it the unwound DNA would remain single stranded.
What is the difference between negative supercoiling and positive supercoiling in DNA structure?
Negative supercoiling refers to the twisting of DNA in the opposite direction of its natural helical structure, resulting in a more compact and twisted form. Positive supercoiling, on the other hand, involves the twisting of DNA in the same direction as its natural helical structure, leading to a more relaxed and unwound form.

What is unwound DNA called?
Unwound DNA is called single-stranded DNA (ssDNA). This type of DNA consists of a single strand of nucleotides, as opposed to the double helix structure formed by two complementary strands of DNA. Single-stranded DNA is often involved in processes such as DNA replication and gene expression.
How does RNA polymerase attach to unwound DNA during transcription?
RNA polymerase attaches to unwound DNA during transcription by recognizing and binding to specific promoter sequences on the DNA strand. Once bound, the RNA polymerase begins to synthesize a complementary RNA strand using the DNA template.
Are chromosome more condense than chromatin?
Yes, you can think of chromosomes tightly wound up DNA and chromatin as unwound DNA.
How does DNA replicate itself when cells divide?
The DNA double helix is unwound and each strand acts as a template for a new double helix.
What is the enzyme that reduces the twisting forces when DNA replicates?
gastric juice
What is the function of CL buffer in DNA extraction?
In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.
What is the process by which DNA separates during replication?
During DNA replication, the process by which DNA separates is called DNA unwinding. This occurs when the double helix structure of DNA is unwound by enzymes, allowing the two strands to separate and serve as templates for the synthesis of new DNA strands.
What prevents DNA stands from attaching to one another During DNA replication?
dna is that because the structures of what is does. and how it reacts
What prevents the wrong nucleotide from DNA replication?
ribosomes
