Is DNA replication conservative or semi conservative?
Semi conservative. The double strand splits into two strands and then a strand is replicated from the template of the two strands constructing four total strands. Two original and two copies.
Why initial denaturation step is done before denaturation step in PCR?
To make sure the double-strand DNA template is separated into single strands.
What does semi-conservative men in regard to DNA replication?
It means when the DNA is unzipped into two strands each strand serves as a template for the synthesis of another new strand. So, when the strands come back together in the double helix one strand is an old strand and one is a new strand with you now have double the DNA you started with; four strands in all.
When forming new DNA molecules each strand of DNA your act as a?
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.
The weak chemical bonds importat in holding the DNA double helix together is the?
The two strands of DNA nucleotides are held together by hydrogen bonds between complimentary nitrogen bases. Adenine pairs with guanine and cytosine pairs with thymine. When it is time for a cell to reproduce, and during protein synthesis, an enzyme called helicase breaks the hydrogen bonds between the two strands. This way DNA can be replicated in preparation for cell reproduction or it can be used as a template for protein synthesis.
Then the two single strands of?
There are two single strands which are found in the DNA molecule. Each of strand will act as the template for the next one in the double helix molecule.
Is DNA replication conservative or semi conservative?
Semi conservative. The double strand splits into two strands and then a strand is replicated from the template of the two strands constructing four total strands. Two original and two copies.
Why is DNA replication caled semiconverative?
Because when the two strands of the double helix are unwound for replication each strand acts as a template to replicate a new strand onto. So, you get four strands, two pair. One of that pair is a new strand and one of the pair is the old strand that was the template strand.
Why initial denaturation step is done before denaturation step in PCR?
To make sure the double-strand DNA template is separated into single strands.
What takes place during DNA replication?
The DNA double helix unwinds, & the two separated strands each serve as a template for a complementary strand to be synthesised

What is the explanation for the process of replication?
During DNA replication, the DNA molecule separates into two strands, then produces two new complementary strands following the rules of base pairing. Each strand of the double helix of DNA serves as a template, or model, for the new strand.

What does helicase do in replication?
(Apex) It breaks apart the bases.
What are the two DNA strands?
The two stands wound together in the DNA can be called any number of names depending on the chemical phenomenon occuring. During replication, the strands are called the leading and lagging strand. During transcription, they are called the sense and the non-sense strands. Basically, both strands are polynucleotides.
DNA molecules has how many strands?
DNA molecule is normally double stranded
