DNA is made of of two complimentary strands, the coding strand and the template strand. When DNA is transcribed (made into messenger RNA which can be converted by ribosomes into proteins) the DNA splits open and free nucleotide bases bind to the template strand. DNA is made of T/C/G/A and RNA is made of U/C/G/A nucleotide bases. G and C bind (they are said to be 'complimentary') A and T bind and in RNA U and A bind (so U replaces T.) The newly formed RNA strand (made on the template stand of DNA) is 'complimentary' to the template but the same as the coding strand of DNA. Hence the template is used to produce RNA which is a copy of the coding strand. Either strand of DNA can act as the template/coding strand.

How does RNA polymerase use DNA?
it separates the DNA strands to create a template for RNA bases
When DNA replicates the new strand is what to the original strand?
The original strands provide a template for making new strands.
Do two DNA strands need to be separated before DNA replication or transcription can occur?
Yes. Also, of the two strands of DNA, only one is the template that will be transcribed, while the other strand is a noncoding strand of DNA.
At the end of DNA replication two new strands of DNA have been produced giving a total of?
Two new DNA chains are formed at the end of DNA replication, both identical in sequence to the template (or parent) chain. These chains are composed of 2 complimentary strands. It is important to note that of the newly formed DNA chains, one strand is the same as the template strand and the other one is a newly synthesized one.
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.

What are the two single strands of DNA?
The strand used as a template for mRNA during transcription is called the antisense strand. The DNA strand not used as a template is called the sense strand.Read more: What_are_the_two_DNA_strands

What does semi-conservative model mean?
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.
What is the complementary DNA strands?
A complementary strand of DNA contains the template information for the creation of a new copy of the other strand. How is it determined?
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.
What type of DNA molecule forms as a result o DNA replication?
During DNA replication the two strands of the DNA helix split apart and the ribosome reads off the template strand producing an exact copy of this strand. Then RNA polymerase base pairs both of the strands, producing 2 semi-conservative strands.
What initially determines which DNA strand is the template strand and therefore in which direction RNA polymerase ii moves along the DNA?
the specific sequence of bases along the DNA strands
What must happen to DNA strands before transcription can begin?
DNA strands must unwind and the two strands must separate prior to transcription beginning. Once transcription is complete, the two strands join back together.
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
