To know what is protein could be of great importance in order to understand how the cells function. Proteins are one of the three most important classes of large biological molecules – nucleic acids, proteins and carbohydrates. Protein consists of one or more than one chain of amino acid residues. To understand what is protein, […]
Protein Synthesis Steps In Brief The process of protein synthesis translates the codons (nucleotide triplets) of the messenger RNA (mRNA) into the 20-symbol code of amino acids that build the polypeptide chain of the proteins. The process of mRNA translation begins from its 5′-end towards its 3′-end as the polypeptide chain is synthesized from its […]
Protein synthesis is one of the most fundamental biological processes by which individual cells build their specific proteins. Within the process are involved both DNA (deoxyribonucleic acid) and different in their function ribonucleic acids (RNA). The process is initiated in the cell’s nucleus, where specific enzymes unwind the needed section of DNA, which makes the DNA in this region accessible and a RNA copy can be made. This RNA molecule then moves from the nucleus to the cell cytoplasm, where the actual the process of protein synthesis take place.
Polycistronic vs Monocistronic Polycistronic mRNA refers to a messenger RNA which encodes two or more proteins. Polycistronic messenger RNAs participates in the process of protein synthesis (translation) in prokaryotes. Many bacterial mRNAs are fully functional in their primary composition transcripts meaning that they do not require any posttranscriptional modifications. In prokaryotes an mRNA molecule usually […]
tRNA Structure Transfer RNA (or abbreviated as tRNA) is small RNA molecule, typically between 70 to 90 nucleotides in length, which main function is to deliver amino acids required for the process of protein synthesis. tRNAs are carrying amino acids to the ribosome, where the actual protein synthesis takes place. The molecule is directed by […]
