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.
6 ημέρες πριν · RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil.
6 ημέρες πριν · Messenger RNA, molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). Each mRNA molecule encodes information for one protein.
24 Μαΐ 2024 · When the mRNAs enter cells in the body, the cells use the mRNAs to produce virus proteins and display them to the immune system. This teaches the immune system to recognize the virus, promoting a strong response if the immune system encounters the virus, protecting the person in the future.
21 Απρ 2024 · Proteins within a cell have many functions, including building cellular structures and serving as enzyme catalysts for cellular chemical reactions that give cells their specific characteristics. The three main types of RNA directly involved in protein synthesis are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA).
The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins. In reality, there is much more to the RNA...
15 Οκτ 2020 · A type of RNA called messenger RNA (mRNA) uses this copying function to ferry genetic data from DNA to the ribosomes, the protein-producing components of the cell, according to the University...
