What else can I help you with?
In RNA thymine is absent and what is substituted?
Uracil is substituted. Uracil is complementary to adenine in RNA. In DNA, adenine is complementary to thymine.
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.
Why is U the fourth nucleotide in the RNA that is synthesized?
Uracil (U) is the fourth nucleotide in RNA because it serves as a substitute for thymine (T), which is found in DNA. In RNA synthesis, uracil pairs with adenine (A) during transcription, allowing for the formation of complementary base pairs. The incorporation of uracil instead of thymine simplifies the RNA structure and is evolutionarily advantageous for RNA's transient functions. Thus, U is fundamental to RNA's role in protein synthesis and regulation.
Which nitrogen base is the complementary base for adenine during transcription?
Thymine is the complementary base for adenine during DNA transcription. During RNA transcription, however, uracil is the complementary base for adenine.
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 does RNA have instead of thymine in its nucleotide structure?
RNA has uracil instead of thymine in its nucleotide structure.
Does RNA have uracil or thymine in its nucleotide structure?
RNA contains uracil in its nucleotide structure, not thymine.
Does RNA contain thymine or uracil in its nucleotide structure?
RNA contains uracil in its nucleotide structure, not thymine.
What nitrogen base is complementary to adenine?
Thymine nitrogen base is complementary to Adenine.
In RNA thymine is absent and what is substituted?
Uracil is substituted. Uracil is complementary to adenine in RNA. In DNA, adenine is complementary to thymine.
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.
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.
In RNA the nucleotide is substituted for?
thymine....uracil is its substitution.
What nucleotide complements adenine?
Thymine in DNA, and Uracil in RNA
What is the matching of complementary nucleotide bases?
The nucleotide "A" base pairs with the nucleotide "T", Similarly, the nucleotide "C" base pairs with the nucleotide "G", and in the same way, The nucelotides "T" and "G" base pairs with nucleotides "A"and "C" respectively. The complementary nucleotide sequence is thus the base pair with which it forms a double-stranded structue of the DNA, for example the complementary sequence for "ACGTTTA" is "TGCAAAT".
A nitrogen base in RNA that is complementary to thymine is?
Thymine is not present in RNA, only in DNA. The base pairs for RNA are adenine & uracil, and guanine & cytosine. Uracil replaces Thymine in RNA.
Adenine bonds to what?
Adenine bonds with Thymine.Adenine complementary stand is Thymine in DNA but in RNA Thymine is replaced with Uracil. This means that Adenines complementary stand is Uracil in RNA.
