What are the nucleotides of DNA and RNA?
​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 are the five nucleotides found in DNA?
Names of Nucleotides The five bases are adenine, guanine, cytosine, thymine, and uracil, which have the symbols A, G, C, T, and U, respectively.
What are the nucleotide bases in RNA?
RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine.
Is RNA a nucleoside?
Nucleosides (bottom) are made of a nitrogenous base, usually either a purine or pyrimidine, and a five-carbon carbohydrate ribose. A nucleotide is simply a nucleoside with an additional phosphate group or groups (blue); polynucleotides containing the carbohydrate ribose are known as ribonucleotide or RNA.
What is difference between DNA and RNA?
Thus, the major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation.
What are the 2 types of nucleotides?
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).
What are the bases found only in RNA?
In this manner, which base is found only in nucleotides of RNA? 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. The bases are often abbreviated A, G, C, T, and U, respectively.
What are the names of the five bases of a nucleotide?
The five bases are adenine, guanine, cytosine, thymine, and uracil, which have the symbols A, G, C, T, and U, respectively. The name of the base is generally used as the name of the nucleotide, although this is technically incorrect.
What are the two pyrimidine bases found in DNA?
The two pyrimidine bases found in DNA are cytosine (C) and thymine (T), and the two pyrimidine bases found in RNA are cytosine and uracil (U). The only difference between thymine and uracil is the presence of a methyl group in thymine that is lacking in uracil. A base plus a sugar is called a nucleoside.
Where are the bases of thymine found in DNA?
The basesadenine, guanine, and cytosine are foundin both DNA and RNA; thymine is found onlyin DNA, and uracil is found onlyin RNA. The basesare often abbreviated A, G, C, T, and U, respectively. For convenience the single letters are also used when long sequences of nucleotidesare written out. What is an example of a nucleotide found in DNA?
