19 Μαρ 2016 · RNA processing is the modification of primary RNA transcripts into mature RNA molecules. It involves removal of introns through splicing and addition of modifications like 5' capping, 3' polyadenylation tail, and RNA editing.
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.
13 Ιουν 2016 · 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.
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.
24 Ιουλ 2014 · RNA. Do Now: Turn in Lab (Strawberry DNA) Begin working on the 10-1 review guide – it will be your homework tonight. RNA: Ribonucleic Acid. RNA is a polymer of nucleotides, just like DNA. There are a few important differences though: RNA processes information, DNA stores it. 216 views • 11 slides
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.
The first step in decoding these genetic instructions is to copy part of the base sequence from DNA into RNA (RNA, like DNA, is a nucleic acid that consists of a long chain of nucleotides). RNA then uses the base sequence copied from DNA to direct the production of proteins.
