8 Οκτ 2014 · RNA is one of the major biological macromolecules essential for life. It has several types that serve different functions. Messenger RNA (mRNA) carries genetic information from DNA to the ribosomes for protein synthesis. Ribosomal RNA (rRNA) is the catalytic component of ribosomes and is involved in protein translation.
2 Μαρ 2013 · RNA- A polymer of ribonucleotides, is a single stranded structure. There are three major types of RNA- m RNA,t RNA and r RNA. Besides that there are small nuclear,micro RNAs, small interfering and heterogeneous RNAs. Each of them has a specific structure and performs a specific function. Read more. 1 of 36. Download now.
13 Ιουν 2016 · 1. The document discusses RNA synthesis and processing, including the different types of RNA (mRNA, rRNA, tRNA), the process of transcription, initiation, elongation, and termination. 2. It also covers RNA processing after transcription, including 5' capping, polyadenylation, splicing, and modifications to tRNA, rRNA and other non-coding RNAs. 3.
Different types of RNA. Messenger RNA (mRNA) – carries copies of instructions for assembling amino acids into proteins. Ribosomal RNA (rRNA) – structural part of ribosomes. Transfer RNA (tRNA)...
5 Transcription – the process in which a molecule of DNA is copied into a complementary strand of RNA. The result is a single strand of RNA (therefore it is not an exact copy of the DNA)… Very much like replication, but instead of making DNA, RNA is made.
The first step involves RNA polymerase, an enzyme that unwinds and unzips the double helix to access a protein-coding gene. The gene's DNA sequence is used as the template for transcribing an RNA copy of that gene, which the polymerase assembles from a chain of nucleotides.
9 Νοε 2014 · RNA is a nucleic acid called Ribonucleic Acid Functions of RNA: • RNA transfers genetic information from the nucleus (DNA) to the cell (proteins) for use. • Makes up ribosomes • Helps assemble proteins
