What make up both side of DNA double helix ladder?
The sides of the DNA double helix ladder is composed of alternating phosphate groups and deoxyribose sugars.
How many stands make up DNA double helix?
The DNA double helix contains two coiled biopolymer strands. The double helix was discovered by James Watson and Francis Crick.
How do you make a double helix model?
One way might be to get a flexible ladder and then turn both ends in opposite directions on its axis, in other words twist it. The result should be quite similar to a DNA double helix. You can use beads: http://www.instructables.com/id/The_Double_Helix_Glass_Bead_DNA_model/
What are the four nitrogen bases that make up the rungs of the double helix?
In DNA, the four bases are: adenine, guanine, thymine and cytosine.
How many strands of nucleotides make up DNA double helix?
In dna there are 4 strands which join each part of the dna together, these are t and a , and g and c each one of these contains 200-3000 atoms depending on wether it dna or mrna
Describe The structure of the double helix?
The structure of a DOUBLE HELIX is called the sugar phosphate backbone and gives the double helix its crisscrossing spiral appearance and it also has the job of holding everything together on the double helix, [Ex.: The sugar phosphate backbone is like the sides of a ladder, its what the bars in the middle of the ladder are attached to, (Bars= HYDROGEN BONDS) and without the sides of the ladder (without the sugar phosphate backbone) the middle bars can't make up the ladder (just like hydrogen bonds can't make up a double helix without something supporting it, not including the other parts of a double helix such as the nitrogenous bases, the nucleotides, the phosphate, and the sugar KNOWN AS DEOXYRIBOSE FOUND ONLY IN A DOUBLE HELIX.)]A single helix sugar is different from a double helix sugar, a single helix sugar is called ribose and a double helix sugar is called deoxyribose.
Did James Watson make the double helix?
Watson and Crick were the first to figure out the shape of DNA, which turns out to be a double helix. They did not make it, they observed it.
Double helix definition?
the double helix refers to the SHAPE OF A DNA MOLECULE!!! It isn't that hard of a connection to make.
What make up both side of DNA double helix ladder?
The sides of the DNA double helix ladder is composed of alternating phosphate groups and deoxyribose sugars.
What are the smaller molcecules that make up nucleic acid called?
The backbone of a nucleic acid is made up of alternating sugar and phosphate molecules bonded together to these are attached the molecule making the rungs of the double helix ladder the Nucleotides.
How many stands make up DNA double helix?
The DNA double helix contains two coiled biopolymer strands. The double helix was discovered by James Watson and Francis Crick.
What discovery did Watson and Crick make about the structure of DNA?
They discovered the double helix.
What molecules come together to make a DNA molecule?
Nucleotides which formed double helix.
What forms the backbone of the DNA double helix molecule?
The backbone of a DNA chain is sugar and phosphate groups of each nucleotide.

What are the four nitrogen bases that make up the rungs of the double helix?
In DNA, the four bases are: adenine, guanine, thymine and cytosine.
How did x-ray diffraction photographs help Watson and crick determine the structure of DNA?
It helped reveal the characteristic shape of a double helix
