The following points highlight the four main processes to produce mRNA from RNA. The processes are: 1. Splicing 2. Capping 3. Polyadenylation 4. RNA Editing. Process # 1. Splicing: This process takes place in the nucleus and involves the removal of noncoding intron sequences from pre-mRNAs to produce mature mRNAs in which the coding sequences, corresponding to the exons, are [...]
This article will update you about the difference between DNA and RNA. Difference # DNA: 1. DNA is the usual genetic material. 2. DNA is usually double stranded, except certain viruses where DNA is single stranded e.g., φ x 174) 3. The pentose sugar is deoxyribose. 4. The common organic bases are adenine, guanine, cytosine and thymine. 5. Regarding base [...]
In this article we will discuss about:- 1. Structure of Ribose Nucleic Acids 2. Types of RNA 3. Replication. Structure of Ribose Nucleic Acids: It is also a polynucleotide but the pentose ribose has a free hydroxyl group in position 2'. It is a long chain polynucleotide which exist in a regular conformation like a double-chain DNA although some viruses [...]
