Question

Which nucleotide replaces thymine during the transcription process when RNA is synthesized?

पर्याय

• Adenine

• Cytosine

• Uracil

• Guanine

Answer 1

During transcription, RNA is synthesized from a DNA template strand by RNA polymerase. In RNA, uracil replaces the thymine found in DNA. This is a fundamental characteristic of RNA structure that distinguishes it from DNA.
