What else can I help you with?
The location where the DNA molecule becomes unzipped is called?
The location where the DNA molecule becomes unzipped is called the replication fork. This is where the two strands of the double helix separate during DNA replication to allow for the synthesis of new complementary strands.
Chromosomes during prophase are made up of two identical strands What are these strands called?
The two identical strands of a chromosome are called chromatids. DNA replication occurs in the interphase stage of the cell cycle.
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 causes two strands of DNA to split?
The answer depends on the circumstances! In a cell, during DNA replication or during translation, the two strands in a DNA molecule are separated by enzymes called topoisomerases and helicases. In a solution, the two strands of a DNA molecule can be separated by being heated. This is called DNA melting. See: http://en.wikipedia.org/wiki/DNA http://en.wikipedia.org/wiki/DNA_melting
What must happen to DNA strands before transcription can begin?
The DNA strands must separate or unwind to expose the specific gene that is going to be transcribed. This process is facilitated by enzymes that help unzip the double-stranded DNA. Once the DNA is unwound, RNA polymerase can then bind to the DNA and initiate transcription.
The two coiled up strands of DNA within a chromosome are called?
The two coiled up strands of DNA within a chromosome are called chromatids. During cell division, chromatids separate and are distributed to daughter cells.

The location where the DNA molecule becomes unzipped is called the replication fork. This is where the two strands of the double helix separate during DNA replication to allow for the synthesis of new complementary strands.

Y shaped regions where the 2 strands of DNA separate?
Replication forks are Y-shaped regions where the two strands of DNA separate during DNA replication. At the replication fork, the DNA helicase enzyme unwinds the double helix structure, creating two single strands that serve as templates for DNA synthesis by complementary base pairing.
What causes two strands of DNA to split?

What chemical force must be overcome in order to separate the two DNA strands during replication?
Hydrogen bonds between the complementary base pairs must be overcome to separate the two DNA strands during replication. Breaking these bonds allows the strands to unwind and separate, enabling DNA polymerases to replicate each strand.
What must happen to DNA strands before transcription can begin?
The DNA strands must separate or unwind to expose the specific gene that is going to be transcribed. This process is facilitated by enzymes that help unzip the double-stranded DNA. Once the DNA is unwound, RNA polymerase can then bind to the DNA and initiate transcription.
The first step of DNA replication is to copy part of the DNA sequence into?
The first step of DNA replication is to unwind and separate the two strands of the double helix. This process is initiated by enzymes called helicases. Once the strands are separated, they serve as templates for the synthesis of new complementary strands.
Do two DNA strands need to be separated before DNA replication or transcription can occur?
Yes. Also, of the two strands of DNA, only one is the template that will be transcribed, while the other strand is a noncoding strand of DNA.
What is the helicase enzyme?
Helicase is an enzyme that plays a critical role in DNA replication by unwinding the double-stranded DNA helix into two separate strands. This process is necessary for DNA polymerase to access the DNA template and synthesize new strands during replication.
Which is the function of the DNA helicase enzymes in the DNA replication process?
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.
