How does heating double stranded DNA separate the strands?
Jamilmcquinn21
The DNA double helix is separated by an enzyme called DNA helicase. This enzyme unzips the double helix and the strands are then held apart by single-strand binding proteins. DNA polymerase then copies each parent strand of the DNA.

∙ 14y agoThe two major bonds present within a DNA are covalent bond, present between the phosphate group and the deoxyribose, and hydrogen bond, present between the two nitrogen bases. Because a hydrogen base can broken down with heat, heating up DNA will ultimately break all the hydrogen bonds present between the bases, causing the DNA to separate.

Which molecule is responsible for separating double-stranded DNA into single strands?
At high temperatures, DNA denatures into single strands. A temperature around 95 degrees should work.
DNA molecules has how many strands?
DNA molecule is normally double stranded
How many strands is DNA made of?
DNA is composed of two strands of DNA nucleotides.
What is it called when DNA separate into two strands?
DNA Replication by enzymes that copy DNA for chromosomes in the new cell after cell division (mitosis)
What bond is responsible for holding the two strands of double stranded DNA together?
Hydrogen bonds are responsible for holding the two strands of DNA together.
Can single strands obtained by heating of double stranded DNA be recombined after cooling?
Of course they can
How many stands are in DNA?
DNA is double-stranded, unless it has been denatured, then the two strands separate, forming two single-stranded molecules.

DNA molecules has how many strands?
DNA molecule is normally double stranded
How many strands is DNA made of?
DNA is composed of two strands of DNA nucleotides.
What are the two strands of a double stranded chromosome called?
The double helix.
Are DNA single stranded?
no dna s are of double strands only
Are DNA single-stranded?
no dna s are of double strands only
What is the indiviual strands of a double-stranded chromosome joined together by?
Chromatid
Which is the function of the DNA helicase enzymes in the DNA replication process?
DNA helicase "unzip," or separate, a strand of DNA at positions called origins. This means that the hydrogen bonds between complementary base pairs are removed (DNA is double stranded!). When they separate double-stranded DNA into single strands, it allows each strand to be copied (replication). DNA helicases use the energy stored in a molecule called ATP to break the bonds, which serves as the energy currency of cells.
Why the amount of DNA produced with pcr is expected to double with each cycle?
double stranded DNA into single stranded DNA meaning that 2 DNA strands can be produced
How many strand does DNA have?
DNA is double stranded (2 strands). However, it is noted that there are some viruses with single-stranded DNA.
