old is broken but new is not
replicated DNA is made of one old strand and one new strand.
semiconservative replication - original DNA double strand will unwind into 2 strands, so one original strand will serve as a template for synthesizing a new complementary strand , thus forming a new DNA (one with old strand and one with a new strand)
Refers to semi-conservative replication of DNA. One strand of the old DNA is used as a template to replicate the other, new, strand of DNA. Thus you have four from two, but two of the four are old strands while the other two strands are new. Thus the name semi-conservative replication.
The process of DNA replication is described as being semi-conservative. The complementary DNA strands are pulled apart, new matching nucleotides are connected to each separate strand, and the result is two new strands that each contain exactly one-half of the original DNA strand.
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
In DNA replication, an existing DNA strand (template strand) is used to guide the assembly of a new complementary DNA strand. Enzymes like DNA polymerase add complementary nucleotides to each template strand, resulting in two identical DNA molecules. This process ensures accurate transmission of genetic information during cell division.
The complementary base pairing between adenine and thymine, and between cytosine and guanine, allows the old strand and the new strand of DNA to come back together during DNA replication. This pairing ensures the accurate synthesis of the new DNA strand.
DNA first unwinds by the polymerase into two strands, then polymerases run over the two strands, replace a new strand on each old strand, forming two new DNA with one new strand and one original strand in each. (The polymerase is the enzyme)
each new DNA double helix consists of one old strand and one new strand
DNA replicates semiconservatively. This means 50% of the parent DNA is retained in each new molecule/double helix. DNA unzips and allows 2 new sugar-phosphate backbones to be inserted, each 'reading' off one of the old strands. While 'reading' enzymes add the complementary base pairs, pairing up each new strand with one of the parent strands. Thus when it is finished replication, each new strand will be bonded to each old strand. there will be a 1:1 ratio of old strand to new strand, thus a 50% remain of parental strand in the new strand.
DNA strands are said to be complementary because they both match up with eachother; A with T and C with G. So if you have the strand ATGGCTA the complementary strand (the other half of the double helix) would read TACCGAT. So if you know one side of the strand then you can describe the whole.
