In 1953,JAMES WATSON and FRANCIS CRICK porposed the model for the structure of DNA. According to them DNA molecule consist of two polynucleotide strands which are twisted around each other in the form of DOUBLR HELIX. The double helic looks like spiral staircase of uniform diameter. The two poly nucleotide strands held in their helical configuration by the hydrogen bonds present between them. ADDENINE always pair up with guanine and thymine is always pair up with cytosine.HYDROGEN BONDS are present between the ADDENINE and GUANINE , CYTOSINE and THYMINE. Two hydrogen bonds are present between the ADDENINE and GUANINE while three hydrogen bonds are present between CYTOSINE and THYMINE. Due to these hydrogen bonds DNA keeps its shape.

What does semi-conservative mean regard to DNA replication?
replicated DNA is made of one old strand and one new strand.
What DNA strand would bond opposite?
assuming that 5' CTGA 3': 3' GACT 5'
Covalent bonds between the sugar of one nucleotide and the of the next nucleotide bond nucleotides together in a DNA strand.?
Covalent bonds that sugar as one of one nucleotide to the next bond is together done come together as a DNA strand. This is taught in science.
A bonds with what?
Adenine bonds with thymine in a DNA strand, however, in an RNA strand, Adenine bonds with uracil.
What does a bond with?
Adenine bonds with thymine in a DNA strand, however, in an RNA strand, Adenine bonds with uracil.
What is a strand of DNA composed of?
hydrogen bonds
What must be broken for DNA strand to be separate?
Hydrogen Bonds
What must be broken for the DNA strand to separate?
Hydrogen Bonds Must be broken
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 Adenine A bond with?
Adenine bonds with thymine in DNA and uracil in RNA.
What must be broken for the DNA strand to separte?
DHISS DiKC
How many total hydrogen bonds would exist between the dna strand and its complementary strand 5'ACTCTAG 3'?
15
When the DNA strand is ready to copy what happens?
When the DNA strand is ready to copy, it basically splits in half and new hydrogen bonds come in to replace the missing half. This process is called translation (I believe).
What types of linkage joins the nucleotides a within a single DNA strand and b between two single DNA strands?
Hydrogen Bonds
Where does Helicase attach to on the DNA strand?
Enzyme helicase unwinds the DNA by breaking the bonds between nucleotides. Thus attaches itself at the nucleotides.
