What are the parts of nucleotide and how do they differ to each other?
A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine. A nucleotide within a chain makes up the genetic material of all known living things.
What is the main difference between the four nucleotides?
4 replies. The nucleobases. I.e. the structure of the nitrogenous base are different. 2 belongs to the purine family adenine and Guanine and 2 belongs to pyrimidine cytosine and thymine.
Which part of a nucleotide varies from nucleotide to nucleotide?
A nucleotide consists of a phosphate group, a sugar, and a nitrogenous base. The phosphate group never varies.
What is the one part of the nucleotide?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
What is the difference between nucleotide?
The main difference lies in their molecular composition as Nucleosides contain only sugar and a base whereas Nucleotides contain sugar, base and a phosphate group as well. A nucleotide is what occurs before RNA and DNA, while the nucleoside occurs before the nucleotide itself.
What is different about the nucleotides that make up DNA?
Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). Then, during DNA replication, the two strands in the double helix separate.
Which component can vary from one nucleotide to the next?
The adenosine phosphate nucleotides have ribose as the five carbon sugar and adenine as the nitrogenous base. These nucleotides differ in the number of inorganic phosphate groups phosphorylated to the ribose, which can vary from one to three.
Which component varies from one nucleotide to another in DNA and RNA?
So DNA and RNA nucleotides differ according to which five-carbon sugar is present, and whether the nitrogenous base thymine or uracil is present. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil.
What are parts of nucleotides?
In turn, each nucleotide is itself made up of three primary components: a nitrogen-containing region known as a nitrogenous base, a carbon-based sugar molecule called deoxyribose, and a phosphorus-containing region known as a phosphate group attached to the sugar molecule (Figure 1).
What is the one part of the nucleotide that differs among?
Aside from its nitrogen bases, all nucleotides are similar. The bases will either be adenine, cytosine, guanine, uracil, or thymine. The one part of the nucleotide that differs among the other different nucleotides is the nitrogenous base.
How is the phosphate group different from a nucleoside?
The Phosphate Group. The phosphate group (PO 4) is what differentiates a nucleotide from a nucleoside. This addition changes the nucleoside from a base to an acid. These phosphate groups are important, as they form phosphodiester bonds with the pentose sugars to create the sides of the DNA “ladder”.
How are the bases of DNA and RNA different?
The only other difference in the nucleotides of DNA and RNA is that one of the four organic bases differs between the two polymers. The bases adenine, guanine, and cytosine are found in both DNA and RNA; thymine is found only in DNA, and uracil is found only in RNA.
How are nucleotides linked together in the double helix?
Nucleotides at least contain one phosphate group. Phosphate of one nucleotide attaches to the 3 rd C-OH group of the sugar of the 2 nd nucleotide, thereby forming 5’ → 3’ linkage. In DNA (double helix) there are two antiparallel strands of polynucleotides that are linked together by hydrogen bonds between nitrogenous bases.
