Transcription process of RNA
Transcription Process
It is the one of the first process of gene expression. RNA polymerase which an Enzyme copies of a particular segment of DNA into RNA. Transcription unit is a stretch of DNA transcribed into an RNA molecule. It is function is to encode at least one gene. Suppose if gene encodes protein than mRNA is produced by a transcription. A protien encoded by DNA transcription unit may comprise a coding sequence. Copare to DNA replication , transcription has a lower fidelity.
Process :-
Transcription of DNA into RNA is govened by the complementary base pairs of the two nucleic acid. Both DNA and RNA are complementary to each other with one exception. The Thymine is replaced by Uracil in RNA. During the transcriptional process, DNA dependent RNA polymerase begin to read a segment of DNA which is transcribed into complementary RNA.
