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 reagents do you use in pcr?

in pcr technique we take original dna first heat it to separate to strands in thermocycler then add rna primer after the formation of about 10 sequences on both parental strands add dna polymerase to construct further


In order to replicate where do DNA molecules separate?

At the hydrogen bonds between bases with the help of the enzyme helicase.


The enzyme used to separate the strands of DNA is?

DNA Polymerase


The site where the old DNA strands separate and new DNA strands will be synthesized is called the?

replication fork


What chemical force must be overcome in order to separate the two DNA strands during replication?

h bond


Which is not a likely method of DNA replication as determined by the structure of DNA?

Conservative (In which both parental strands reassociate) and Dispersive (In which daughter strands have mixture of parent DNA) both are not the methods of DNA replication


What do heliocases do?

separate strands of nucleic acids (unwind DNA)


It is necessary for DNA strands to be held together with relatively weak hydrogen bonds?

so that the DNA strands can separate easily during replication.


What must be true about DNA strands that have just been produced in DNA replication?

The strands produced have the same generic code


What must occur before replication can begin?

The replication of DNA occurs whenever the cell needs the S shape division. This happens since when we divide, enough DNA is needed to be pass on to our daughters.


Why does one DNA strand grow one nucleotide at a time and the other is assembled in short fragments?

The two strands of parental DNA separate, and each becomes a template for the assembly of a complementary strand from a supply of Why_does_one_DNA_strand_grow_one_nucleotide_at_a_time_and_the_other_is_assembled_in_short_fragmentsnucleotides. The nucleotides line up one at a time along the template strand in accordance with base pairing rules. Enzymes link the nucleotides to form the new DNA strands.Read more: Why_does_one_DNA_strand_grow_one_nucleotide_at_a_time_and_the_other_is_assembled_in_short_fragments
