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


In a molecule of RNA the thymine nucleotide of DNA is replaced by what?

In a molecule of RNA, the thymine nucleotide found in DNA is replaced by uracil. While thymine pairs with adenine in DNA, uracil also pairs with adenine in RNA during the process of transcription. This substitution is one of the key differences between DNA and RNA structure.


What nucleotide base is part of transcription that is not part of the DNA?

During transcription, uracil is the nucleotide base that is incorporated into RNA but is not found in DNA. In RNA, uracil replaces thymine, which is present in DNA. This substitution occurs as RNA polymerase synthesizes RNA from the DNA template, pairing uracil with adenine.


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.


In RNA which nucleotide base binds to guanine?

In RNA, the nucleotide base that binds to guanine is cytosine. Guanine and cytosine form complementary base pairs through hydrogen bonding, similar to their pairing in DNA. In RNA, adenine pairs with uracil instead of thymine, which is found in DNA.


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).
