<span>The cartilaginous rings in the trachea and the costal cartilage connects the ribs to the sternum. The same cartilage type is also found in articulating joints. The purpose of the specific cartilage is to give a smooth surface that connects and ends at the articulating bones.</span>
Answer:
Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway
Explanation:
Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
The answer is myelination. This involves the growth of myelin sheath around the axon or neurons, a biological process that occurs at a great pace in a child’s brain during child development after birth. The myelin sheath improves transmission of electrical impulses through a process called saltatory conduction (through hops).
