how is this acid helpful in prokaryotes?
They change shape when they bind metabolites so that they gain or lose the ability to bind chromatin to regulate expression of genes.
RNA
They change shape when they bind metabolites so that they gain or lose the ability to bind chromatin to regulate expression of genes.
what nitrogenous bases are found in a molecule of rna (ribonucleic acid) UNANSWERABLE when was this acid first found? 1959 and by whom? Severo Ochoa as he researched on any other things? Yes, he researched "Classical Physiology". can you tell me one way how this acid is different from dna? Unlike DNA, their structures do not consist of long double helices, but rather collections of short helices packed together into structures akin to proteins. what does this acid compose of? Each nucleotide in RNA contains a ribose sugar, with carbons numbered 1' through 5'. A base is attached to the 1' position, in general, adenine, cytosine, guanine, or uracil. what are some of the sources of this type of sugar? It is typically produced from glucose by the pentose phosphate pathway. does it have any connection with the metabolism of the body? Yes, they act as electron acceptors in biochemical redox reactions in major metabolic pathways including glycolysis, the citric acid cycle, fermentation, and the electron transport chain. can the acid be interfered by mirnas? Post-transcriptional expression levels of many genes can be controlled by RNA interference, in which miRNAs, specific short RNA molecules, pair with mRNA regions and target them for degradation.

RNA [SEP] Regulatory RNA in prokaryotes
They are cis-acting regulatory RNA sequences acting allosterically. They change shape when they bind metabolites so that they gain or lose the ability to bind chromatin to regulate expression of genes. Archaea also have systems of regulatory RNA. The CRISPR system, recently being used to edit DNA "in situ", acts via regulatory RNAs in archaea and bacteria to provide protection against virus invaders.
