There are many types of RNAs, but three types of it are described here: 1. Ribosomal RNA (rRNA) 2. Messenger RNA (mRNA) 3. Transfer RNA (tRNA). Type # 1. The Ribosomal RNA (rRNA): The non-genetic RNAs are synthesized on the DNA template and are present in the nucleolus and cytoplasm. Therefore, the base sequences of rRNA and part of DNA [...]
The below mentioned article provides a note on the process of transcription. Transcription is the process of copying genetic information from one strand of the DNA into RNA. In transcription, only a segment of DNA or only one out of the two stands is copied into RNA. Unlike replication, which once set in, the total length of DNA of organisms [...]
The following points highlight the three main classes of RNA molecules and RNA processing. The classes are: 1. Messenger RNA 2. Ribosomal-RNA 3. Transfer-RNA. Class # 1. Messenger RNA: Messenger RNA (m-RNA) is an informational molecule. The genetic message for protein synthesis contained in DNA is transcribed in the complementary ribonucleotide sequence of m-RNA. A group of three consecutive nucleotides [...]
