Erwin Chargaff discovered that the bases of DNA (adenine, thymine, cytosine, and guanine) attach to the deoxyribose sugars. Chargaff's rules state that in DNA, the amount of adenine always equals the amount of thymine, and the amount of cytosine always equals the amount of guanine.
What else can I help you with?
What are the three main componets that make up DNA?
The groups are 1. Phosphate 2. Deoxyribose sugar 3. Nitrogen base The phosphates and deoxyribose sugars make up the sides of the helix (alternating one after the other) and nitrogen bases are the "rungs" of the helix.
What is the molecules that make the upright of a DNA?
The backbone of DNA is made up of alternating sugar (deoxyribose) and phosphate molecules. The bases adenine, thymine, guanine, and cytosine are attached to the deoxyribose sugars, forming the rungs of the DNA helix.
What are the differences between sugars and bases of nucleotide of DNA and RNA?
Sugars in DNA are deoxyribose, while in RNA they are ribose. Bases in DNA are adenine, thymine, cytosine, and guanine, while in RNA thymine is replaced by uracil. DNA is double-stranded and RNA is typically single-stranded.
Five carbon sugar found DNA and RNA?
The five-carbon sugar found in DNA is deoxyribose, while in RNA, it is ribose. These sugars form the backbone of the nucleic acid molecules, with the bases attaching to them to create the genetic code.
What part of the shape backbone do the bases attach to?
The bases of DNA attach to the sugar component of the backbone, specifically to the 1' carbon of the deoxyribose sugar. The sugar is linked to phosphate groups, forming the backbone of the DNA strand, while the nitrogenous bases extend from the sugars, providing the genetic information.
What compound is composed of deoxyribose sugars and nitrogenous bases?
noah has no friends
What Make up the side of the DNA molecule?
A phosphate group bonded covalently to a sugar molecule.

3 components of DNA?
The three components of DNA are phosphate, deoxyribose sugar, and nitrogen base. A DNA strand looks like a ladder. The "sides" of the ladder are made up by the phosphates and deoxyribose sugars the "steps" are the nitrogen bases.

What substance is the sugar deoxyribose found in?
In deoxyribose nucleic acid. DNA, as part of the backbone the nitrogenous bases are hung on.
Is the backbone of a DNA molecule made up of phosphate molecules and deoxyribose sugars?
Yes, you are correct. DNA is made up of a base (adenine, thymine, cytosine and guanine), a phosphate and a deoxyribose Sugar. The phosphate and the sugar form the backbone while the bases form the links in between
What chemicals connect to what in a dna strand?
The backbone of the DNA molecule is composed of alternating deoxyribose sugars and phosphate groups. The nitrogen bases are bonded to the sugar molecules. The two strands of DNA are held together by hydrogen bonds between the nitrogen bases of both strands.
What factor maintains the same distance between strands in DNA molecules?
Depending on what "Strands" are it could be either Hydrogen bonding between complementary base pairs or Phosphate bonds between interlinking deoxyribose sugars
