More DNA. The DNA unzips and then makes more from the code that genes give, It has to fit A with T and C with G. Mutations happen when the DNA does not unzip on time and the new DNA still sticks to the DNA that was supposed to unzip
== == Duplication of the DNA; often part of mitosis (cell division); growth process.
It results in two new strands of DNA, each with one new strand and one old. This process is called semi-conservitive replication. :-)
DNA replication results in to formation of sister chromatids in a chromosome.
Yes. In theory, DNA replication makes an exact duplicate of the cell's original DNA in preparation for mitosis.
sister chromatids in a chromosome
no. it does not
In the replication part, replication ensures that each new cell will have one complete set of genetic instructions. it does this by making identical strands of chromosomes. transcription enables to adjust to changing demands. it changes certain types of strands on the DNA
Unless mutation occur the two copies of DNA that are made after replication are identical to its original form. Thus continuous replication of DNA in the chromosomes does not alter its nature.
DNA replication is the process in which the hydrogen bonds between the two strands of DNA are broken and then new DNA nucleotides are bonded along each strand according to the base-pairing rule. The result is two identical molecules of DNA.
DNA Replication by enzymes that copy DNA for chromosomes in the new cell after cell division (mitosis)
dna replication. can be summarised as the two helical strands of dna unravelling through the action of enzymes and the corresponding nitrogenous bases of each being matched up (A-T, C-G) to form two identical strands
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
In the replication part, replication ensures that each new cell will have one complete set of genetic instructions. it does this by making identical strands of chromosomes. transcription enables to adjust to changing demands. it changes certain types of strands on the DNA
After DNA replication, there are double the number of chromosomes, which will be divided into two identical daughter nuclei during mitosis. For example, a normal human body cell has 46 chromosomes. When it undergoes DNA replication, the chromosomes are doubled so that there will be 92 chromosomes, consisting of 46 pairs of sister chromatids. During mitosis, the sister chromatids separate into two identical daughter nuclei, each having 46 chromosomes.
Unless mutation occur the two copies of DNA that are made after replication are identical to its original form. Thus continuous replication of DNA in the chromosomes does not alter its nature.
After replication, two identical molecules of DNA are produced, each containing one original strand and one newly synthesized complementary strand. This process ensures that each daughter cell receives a complete copy of the genetic material.
Before cell division, the chromosomes are duplicated through a process called DNA replication. This ensures that each new cell receives a complete set of genetic information. The duplicated chromosomes then align and separate during cell division to ensure each daughter cell receives a copy of the genetic material.
DNA replication is the process in which the hydrogen bonds between the two strands of DNA are broken and then new DNA nucleotides are bonded along each strand according to the base-pairing rule. The result is two identical molecules of DNA.
DNA helicases are enzymes responsible for unwinding the double-stranded DNA helix during replication. They separate the DNA strands by breaking the hydrogen bonds between the complementary base pairs, providing the single-stranded template needed for replication to occur. This process is crucial for allowing DNA polymerase to access the strands and synthesize new complementary strands.
The human chromosomes have hundreds of origins of replication where the DNA unwinds and replication begins. These origins are specific DNA sequences that mark the starting points for the replication process by recruiting the necessary enzymes and proteins. Replication occurs bidirectionally from each origin, ensuring that the entire chromosome is faithfully duplicated.
They should be identical to the original DNA that underwent replication.
They should be identical to the original DNA that underwent replication.
DNA replication occurs because there need to be two identical copies of DNA before the nucleus of the cell divides, so that each new nucleus has a complete and identical copy of DNA.
