Opis:: The genetic code discovered 40 years ago, consists of 64 triplets (codons) of nucleotides. The genetic code is almost universal. The same codons are assigned to the same amino acids and to the same START and STOP signals in the vast majority of genes in animals, plants, and microorganisms. Each codon encodes for one of the 20 amino acids used in the synthesis of proteins. That produces some redundancy in the code and most of the amino acids being encoded by more than one codon. The two cases have been found where selenocysteine or pyrrolysine, that are not one of the standard 20 is inserted by a tRNA into the growing polypeptide.

Opis:: Aminoacyl-tRNA synthetases (AARS) are essential proteins found in all living organisms. They form a diverse group of enzymes that ensure the fidelity of transfer of genetic information from the DNA into the protein. AARS catalyse the attachment of amino acids to transfer RNAs and thereby establish the rules of the genetic code by virtue of matching the nucleotide triplet of the anticodon with its cognate amino acid. Here we summarise the effects of recent studies on this interesting family of multifunctional enzymes.

Tytuł:: DNA – a molecule that transformed science. A short history of research
Autorzy:: Gabryelska, Marta M.
Szymański, Maciej
Barciszewski, Jan
Powiązania:: https://bibliotekanauki.pl/articles/703398.pdf

Tematy:: DNA
molecular biology

genetics
Opis:: Deoxyribonucleic acid (DNA) was identified 140 years ago by a Swiss physician Friedrich Miescher. His discovery was fundamental for the development of biochemistry, genetics and molecular biology. Contemporary biology, biotechnology and medicine largely depends on our ability to analyze, synthesize and manipulate DNA. We present highlights of the history of DNA research from the very beginning to the sequencing of human genome.

Tematy:: 50S subunit structure

5S rRNA
crystal structure
Opis:: The ribosome is a macromolecular assembly that is responsible for protein biosynthesis in all organisms. It is composed of two-subunit, ribonucleoprotein particles that translate the genetic material into an encoded polypeptides. The small subunit is the site of codon-anticodon interaction between the messenger RNA (mRNA) and transfer RNA (tRNA) substrates, and the large subunit catalyses peptide bond formation. The peptidyltransferase activity is fulfilled by 23S rRNA, which means that ribosome is a ribozyme. 5S rRNA is a conserved component of the large ribosomal subunit that is thought to enhance protein synthesis by stabilizing ribosome structure. This paper shortly summarises new results obtained on the structure and function of 5S rRNA.

Opis:: Nervous system is characterized by its uniqueness in cells origin, their variability, electrical properties of the nervous cell membrane, response to external signals, neuronal network and changes in synapses activity that are the basis of higher brain functions, such as learning and memory. Brain is a superior organ of human body with an extremely efficient regulation system. Apart from protein and small-molecule regulators, ribonucleic acids (RNAs), especially noncoding proteins (ncRNAs), play a crucial controlling role in the brain. They are present in every cell, from bacteria to primates and have regulatory, catalytic as well as structural function. Many specific ncRNAs have been identified in human brain, responsible for development and functioning. Disturbances in ncRNA synthesis and mechanism of action are connected to diseases such as autism, schizophrenia, Alzheimer disease, Prader-Willi syndrome and others.
