When your DNA replicates itself, the needed section of the double helix "unzips" into two strands. Each of those strands is called a template. Free nucleotides assemble onto the templates using base pairing with the enzyme DNA polymerase and create a new double helix.

Each DNA strand has a backbone that consists of alternating?
sugar and phosphate units/molecules.
Why the DNA molecule is compared with a twisted ladder?
the whole DNA strand looks like a twisted ladder. the molecules are on the strand.
DNA replication results in two DNA molecules?
Each with one new strand and one original strand.
What is ligase?
This enzyme is used on the lagging strand of DNA and seals the lagging strand to its daughter strand in order to create another double helix DNA
What is important features in synthesis phase?
Synthesis phase or "S phase" occurs during the interphase of a cell cycle between the G1 and G2 stages. During synthesis phase, DNA molecules "unzip" and each old strand attracts free nucleotides forming complementary new strands, leaving two strands of DNA identical to the original strand of DNA.
How DNA replicates?
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 DNA strand has a backbone that consists of alternating?
sugar and phosphate units/molecules.
At the end of replication each new DNA molecule is composed of?
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.
What is the product of DNA replication?
Two molecules of DNA instead of the original one; each molecule now contains one strand from the double helix of the original molecule, and one new strand
What fills in the hand rails of each new DNA strand?
alternating deoxyribose sugar molecules and phosphate groups
Why the DNA molecule is compared with a twisted ladder?
the whole DNA strand looks like a twisted ladder. the molecules are on the strand.
What does RNA polymerase use one strand of DNA as?
No. All strands can be replicated, just depends on where the enzyme decides to land and unzip it. Anyways, all DNA molecules would be adequate templates since they are all identical copies of each other.
Does histones and DNA molecules relate to each other?
Histones are a part of DNA. Histones are actually 8 molecule of proteins joined together and the DNA strand wraps around the the histone in a circular manner. Histones are present on the DNA strand at regular intervals.
DNA replication results in two DNA molecules?
Each with one new strand and one original strand.
What is ligase?
This enzyme is used on the lagging strand of DNA and seals the lagging strand to its daughter strand in order to create another double helix DNA
Why is replication called 'semi-conservative'?
DNA replication is said to be 'semi-conservative' because the two new daughter DNA molecules are "Half old" and "Half new". Half the original DNA molecule is saved, or conserved in the daughter molecules.
The cellular process of creating two new DNA molecules from one original copy is called replication Which statement is the BEST description of this process?
DNA opens up and each strand is used as a template for a new strand.
