What is ATP is composed of?
Sugar, Phosphate and Bases
Which macromolecule has a basic unit that is composed of phosphate a sugar ring and one five different bases?
A nucleic acid.
The nucleotides forming DNA are composed of what three molecular components?
Both DNA and Rna are composed of, first, the sugar-phosphate backbone. The sugar is ribose and the phosphate is a PO4 (-2) moiety. Reaching laterally are the third components - the nucleotide bases.
A DNA nucleotide is composed of?
A nucleotide is composed of a Nitrogenous base, a phosphate, and a ribose sugar.
Is DNA an isotope?
No, DNA is not an isotope. Isotopes are forms of an element with different numbers of neutrons, whereas DNA is a molecule composed of nitrogenous bases, sugars, and phosphate groups that carry genetic information.
What is the RNA made of?
RNA is composed of a phosphate, a ribose sugar, and four nitrogen bases: adenine, guanine, cytosine, and uracil.
What are the sides of the DNA ladder composed of?
The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.
What did PA Levene determine that DNA was composed of?
P.A. Levene was able to determine that DNA was composed of three parts, which are nitrogen bases, phosphate, and sugar. DNA stands for deoxyribonucleic acid.
What are the items used during RNA synthesis?
Enzymes, such as RNA polymerase, and RNA nucleotides, which are composed of the sugar ribose, a phosphate group, and one of four different nitrogen bases: adenine, uracil, guanine, or cytosine.
Why are genes distinguished by bases but not by the sugar-phosphate backbone?
The base sequence is what makes one gene different from another. There are four bases which can be arranged in many different sequences. The sugar phosphate backbone is the same in all the genes. It is impossible to identify a gene by this.
What make up the backbone of a polynucleotide strand?
The backbone of a polynucleotide strand is composed of alternating sugar (deoxyribose or ribose) and phosphate molecules. The sugar-phosphate backbone provides the structural support for the nucleotide bases, which extend from the backbone and form interactions with bases on the opposite strand in DNA or RNA molecules.
What represents the portion of DNA composed of the nucleotides' phosphate groups?
The back-bone of DNA is called 'the sugar-phosphate backbone' because: the ribose [or the 2' [two-prime] deoxy-ribose] sugars that 'make up' the backbone binding portion of the (one of four) nucleotide bases is interlaced with the phosphate moieties. Compare to adding N to the C chain to gain strength.
