What is the enzyme that unwinds DNA prior to replication?
The enzyme that unwinds DNA prior to replication is called helicase. Helicase plays a crucial role in DNA replication by breaking the hydrogen bonds between the base pairs of the double-stranded DNA molecule, allowing the two strands to separate and form the replication fork. This process is essential for the replication of DNA during cell division and ensures that the genetic information is accurately copied.
What molecule unwinds DNA?
A replication bubble.
Which part of the cell unwinds to become chromosomes?
The DNA molecule unwinds from the double helix structure in the cell's nucleus to form chromosomes during cell division. This process allows for the genetic material to be replicated and segregated into the daughter cells.
What happens right before RNA polymerase begins work?
The DNA double helix unwinds.
How does DNA and the histone proteins interact to form the chromosome?
Histone proteins serve as spools around which DNA wraps, forming nucleosomes. The DNA is wound around these protein spools multiple times to create a more compact structure known as chromatin. Further compaction of chromatin leads to the formation of chromosomes.
What does the helicase enzyme do?
Helicase is an enzyme involved in DNA replication. It unwinds and unzips the parental DNA strand.
Is DNA made if chromosomes?
No. DNA is what chromosomes are made of. DNA is wound around proteins like thread on a spool, but since DNA is one long"string", the DNA is wound around many protein "spools", all of which are connected by DNA. This string of DNA/protein "thread on spools" is wound around itself, and wound around itself, and wound around itself a lot more, then (after a pretty intricate process) Wala! You have a chromosome.

What elongates as DNA unwinds and is replicated continuously?
The leading strand elongates continuously as DNA unwinds and is replicated. DNA polymerase synthesizes the new strand in a 5' to 3' direction, allowing for continuous addition of nucleotides.
What is the function of DNA helicare in DNA replication?
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
What molecule unwinds DNA?
A replication bubble.
What is the function of the protein enzyme Dna helicase?
DNA helicase unwinds the double-stranded DNA helix by breaking the hydrogen bonds between the base pairs. This process is essential for DNA replication, repair, and recombination as it allows other enzymes to access the DNA strands for their respective functions.
What unwinds the parental double helix for DNA and whats is the relationship between genes and DNA?
The enzyme Helicase A gene is a small segment of DNA
What job do the enzymes helicase play?
Helicase unwinds the DNA during replication.
Which part of the cell unwinds to become chromosomes?
The DNA molecule unwinds from the double helix structure in the cell's nucleus to form chromosomes during cell division. This process allows for the genetic material to be replicated and segregated into the daughter cells.
What happens right before RNA polymerase begins work?
The DNA double helix unwinds.
What is the role of DNA helicase during both DNA replication and transcription?
DNA helicase plays a crucial role in both DNA replication and transcription by unwinding the double-stranded DNA helix to facilitate the processes. In DNA replication, helicase unwinds the DNA at the replication fork to allow DNA polymerase access to the template strands. In transcription, helicase unwinds the DNA in front of the RNA polymerase to allow for the synthesis of RNA.
