In RNA, the base T is replaced with which nucleotide?

In RNA, the base T is replaced with the nucleotide U (uracil).


What is in Rna that is not in Dna?

The nucleotide base Uracil.


What is the difference between a base and a nucleotide?

A nucleotide is the sugar (in DNA is a deoxyribose in RNA it's ribose), phosphate group and 1 base. A base pair is the "rung in the ladder" for example in DNA it could be adenine + thymine or guanine + cytosine. In RNA the thymine is replaced by uracil


Which of the nucleotides occurs in DNA molecules but not in RNA molecules?

Thymine is a nucleotide that occurs in DNA molecules but not in RNA molecules. In RNA, thymine is replaced by uracil.


Is a adenine an enzyme?

No, it is a nucleotide base used to construct DNA and RNA


What is a nucleotide polymer?

A nucleotide polymer is a long chain made up of nucleotide units bonded together. Each nucleotide consists of a nitrogenous base, a sugar molecule, and a phosphate group. Nucleotide polymers form the backbone of DNA and RNA molecules.


An organic base that contains nitrogen a subunit of a nucleotide in DNA and RNA is?

Adenine is an organic base that contains nitrogen and is a subunit of nucleotides in both DNA and RNA.


What nitrogenous base is not found on DNA but is found on RNA?

Thymine is not found in RNA. It is instead replaced by Uracil.


What is a combination of a sugar a phosphate group and a nitrogen base?

A combination of a sugar, a phosphate group, and a nitrogen base is called a nucleotide. Nucleotides are the building blocks of nucleic acids like DNA and RNA. The nitrogen base can be adenine, guanine, cytosine, thymine (in DNA), or uracil (in RNA).


Describe the parts of a nucleotide?

A nucleotide is made of a phosphate, a sugar and a nitrogenous base. In RNA the sugar is ribose and in DNA it is deoxyribose. The bases in DNA are A, T, G and C. The T is replaced by U in RNA.


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.


Is deoxyribose and uracil found in a DNA nucleotide?

No. Deoxyribose is the sugar in a DNA nucleotide. A DNA nucleotide would also include a phosphate group and a nitrogen base.
