What else can I help you with?
What function does a DNA polymerase have?
To split DNA strands to create doubles.
The site where the old DNA strands separate and new DNA strands will be synthesized is called the?
The site where the old DNA strands separate and new DNA strands are synthesized is called the replication fork. This is where the enzyme DNA polymerase adds nucleotides to the growing DNA strand.
Where do you get your RNA?
Dna is split up into two different strands of nucleotides. After that is beyond me.
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
Genes are arranged on twisted strands called what?
Genes are arranged on twisted strands called DNA. DNA is housed in the nucleus and controls the cells functions and systems.
What is it called when long strands of DNA are wrapped around themselves?
It is called DNA supercoiling. This coiling helps to compact the long strands of DNA into the small space inside a cell.
The junction between separated strands of DNA is called what?
The junction between separated strands of DNA is called a replication fork.
Why do scientists only need a tiny trace of DNA for tests?
The DNA undergoes a process named PCR (Polymer Chain Reaction) once the scientists get a hold of the DNA. essentially the DNA double helix is unwound and is split into its two strands, and random nucleotides (or primers as they are called in this process) attach to the two open strands. These primers form hydrogen bonds with the DNA strands. due to this, there are now two strands of DNA rather than just one. scientists do this over and over again, until they have enough DNA to be able to test whatever they need to test on it.
What are DNA strands packed into?
DNA strands are packed into structures called chromosomes. Chromosomes are made up of long strands of DNA that are tightly coiled and condensed to fit inside the nucleus of a cell.
What is the enzyme that controls the synthesis of new strands of DNA called?
DNA polymerase
When DNA is about to be copied where does it split?
It splits down the middle due to the action of the enzyme helicase. This exposes the nitrogen bases on both strands of the DNA.
What is the name for the area in which these duplicated strands joined?
The area where the duplicated strands join is called the "replication fork." This is where the DNA helicase unwinds the DNA double helix, creating two single strands that serve as templates for the synthesis of new DNA strands.
