What must be broken for the DNA strand to separte?
DHISS DiKC
During DNA replication what two processes must occur before the two stands of a DNA molecules can separate?
Before the two strands of a DNA molecule can separate during replication, the hydrogen bonds holding them together must be broken, and the double helix structure unwound by enzymes such as helicase. This allows the DNA polymerase enzyme to move along each strand and synthesize complementary new strands.
What does semi-conservative mean regard to DNA replication?
replicated DNA is made of one old strand and one new strand.
A fragment of a strand of nucleic acid isolated from a silk moth species contains the base sequence CAGACT The strand must be from?
The base sequence CAGACT corresponds to the DNA strand, and it would be complementary to the RNA strand with the sequence GUCUGA. Therefore, the original strand is the DNA strand.
How does the cell repair a double strand break in DNA?
When a cell encounters a double strand break in DNA, it activates a repair process called homologous recombination. In this process, the cell uses a matching DNA sequence from a sister chromatid as a template to repair the broken strands. Enzymes help align the broken DNA ends with the template, allowing for accurate repair of the double strand break.
What must be broken for DNA strand to be separate?
Hydrogen Bonds

What must be broken down in order for DNA to separate?
Hydrogen Bonds.
At what part will DNA strand separate?
telomeres
What is the role of heat in DNA extraction?
Heat anneals DNA strand i.e. separate two strands of DNA to build anti-codon to desired DNA strand
What is the difference of old and a new strand of DNA?
old is broken but new is not
What sites separate and replicate in DNA?
During DNA replication, the two DNA strands separate at the origin of replication, forming a replication bubble. Enzymes like helicase unwind the DNA strands, while DNA polymerase replicates each strand by adding complementary nucleotides. This process ensures that each newly formed DNA molecule contains one original strand and one newly synthesized strand.
What chemical force must be overcome in order to separate the two DNA strands during replication?
Hydrogen bonds between the complementary base pairs must be overcome to separate the two DNA strands during replication. Breaking these bonds allows the strands to unwind and separate, enabling DNA polymerases to replicate each strand.
What bonds are broken in order the unzip the DNA strands?
The hydrogen bonds are broken in order to unzip the DNA strand. This all occurs during the DNA replication process.
What does semi-conservative mean regard to DNA replication?
replicated DNA is made of one old strand and one new strand.
What must happen to the helix of DNA for transcription to occur?
For transcription to occur, the double helix structure of DNA must unwind and separate at the promoter region of the gene being transcribed. This unwinding exposes the template strand of the DNA, allowing RNA polymerase to synthesize a complementary RNA strand by adding ribonucleotides according to the sequence of the DNA template. The DNA helix reforms after the transcription process is complete.
