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.

5 Ιαν 2020 · • In eukaryotes, the nascent RNA is called primary transcript-RNA – needs to be processed – and transported to the cytoplasm for translation to occur. • The processing steps are: – Addition of a 5’ 7-methyl guanosine cap (capping).
24 Ιουλ 2014 · Transcription • Process in which part of the nucleotide sequence of DNA is copied into a complementary sequence in RNA • RNA polymerase binds to DNA in nucleus and separates the strands • RNA polymerase then reads the DNA template and assembles an RNA strand • DNA zips back up, mRNA formed.
Structure of RNA There are three major types of RNA that participate in the process of protein synthesis: ribosomal RNA (rRNA), transfer RNA (tRNA), and messenger RNA (mRNA).
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
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.
