What chemical force must be overcome in order to separate the two DNA strands during replication?
h bond
What is the helicase enzyme?
Unwinds the DNA during DNA replication and Trancription
What structure will the chromatin become in mitosis?
The chromatin in the cell becomes chromosomes in prophase, the first stage of mitosis. The chromatin coils tightly together to form into separate chromosome strands during this phase.
The two DNA strands that form during mitosis are identical true or false?
True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
In animal cell xhich structure is thougth to produce the spindle fibres that help separate the sister chromatids during anaphase?
Centerioles
It is necessary for DNA strands to be held together with relatively weak hydrogen bonds?
so that the DNA strands can separate easily during replication.
What chemical force must be overcome in order to separate the two DNA strands during replication?
h bond
What is one of the two strands of a chromosomes that become visible during meiosis or mitosis?
daughter strands
What is the helicase enzyme?
Unwinds the DNA during DNA replication and Trancription

True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
What enhances separation of DNA strands during replication?
helicase
Does helicase separates the DNA strands during replication?
yes
Protein strands that attach to the centromere region during M-phase of cell cycle?
During Metaphase the protein strands that attach to the centromere region are called spindle fibres.
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.
Why is it necessary that DNA is packaged into chromosomes?
If DNA remained in a thread-like state it would be very difficult to effectively separate all the individual strands during any type of cell division. Discrete chromosomes created during the pachytene phase are much easier to separate cleanly.
Are the dna strands of an unborn child damage if the mother is on herion during her pregency and how many strands are affected?
Absolutely they are affected. Infinitely many strands. Many variables go into how severe the birth defects will be.
