Thymine is used in DNA instead of uracil because thymine is more stable and less prone to errors during DNA replication. This helps maintain the integrity and accuracy of genetic information.

Which nitrogen base is not used during replication?

Uracil. Uracil is not present in DNA, but it is present in RNA. DNA's "equivalent" base is thymine, meaning when DNA is transcribed into RNA, the places where thymine would go instead has uracil.

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

Uracil is the nitrogenous base that is found on RNA but not on DNA. RNA contains uracil instead of thymine, which is found in DNA.

The bases of RNA are the same as those of DNA with the exception that RNA contains?

uracil instead of thymine.

DNA uses thymine and rna uses what?

RNA uses uracil instead of thymine as one of its nitrogenous bases.

Why does RNA have uracil instead of thymine in its nucleotide structure?

RNA has uracil instead of thymine in its nucleotide structure because during the process of transcription, RNA is made by copying the DNA template. Uracil is used in RNA instead of thymine because uracil can easily pair with adenine, just like thymine does in DNA, allowing for accurate replication of genetic information.
