pav-90 [236]

Answer:

Divisions of the cerebral hemispheres that are named after the overlying skull bones are called Lobes

Explanation:

By means of a prominent groove, called the longitudinal fissure, the brain is divided into two halves called hemispheres. At the base of this fissure lies a thick bundle of nerve fibers, called the corpus callosum, which provides a communication link between the hemispheres. The left hemisphere controls the right half of the body, and vice-versa, because of a crossing of the nerve fibers in the medulla.

The central sulcus and the lateral sulcus, divide each cerebral hemisphere into four sections, called lobes.The central sulcus, also called fissure of Rolando, also separates the cortical motor area (which is anterior to the fissure).

The cerebral cortex is classified into four lobes, according to the name of the corresponding cranial bone that approximately overlies each part. Each lobe contains various cortical association areas – where information from different modalities are collated for processing. Together, these areas function to give us a meaningful perceptual interpretation and experience of our surrounding environment.

One of the central themes in biology is how DNA RNA, and proteins are related. Describe how genetic information flows between Th

igor_vitrenko [27]

Answer/Explanation:

DNA is transcribed into RNA, RNA is translated into protein

The information contained in DNA can be copied (transcribed) onto a molecule of RNA, as these languages are essentially the same (although RNA uses uracil in place of thymidine). This process is carried out by an enzyme called RNA polymerase through the process of complementary base pairing, and occurs in the nucleus. The two strands of DNA are separated, and the RNA polymerase enzyme uses a template strand of DNA to synthesise a new molecule of RNA.

Once the RNA is produced (often called the messenger RNA (mRNA), as it contains the message from the DNA). The RNA is processed, before being exported into the cytoplasm. Here, translation can begin.

Translation is the process where mRNA is converted into a polypeptide sequence, which becomes a mature protein. This process occurs on the ribosome. The mRNA is attached to the ribosome, and special molecules called tRNAs are used to build a polypeptide chain from amino acids.

tRNAs recognise triplet (3 nucleotide) sequences on the mRNA called codons. They possess what is called an "anticodon", which is complementary to a codon on the mRNA, and also corresponds to a particular amino acid.

The ribosome moves along the length of the mRNA, permitting the attachment of tRNAs (and their corresponding amino acids) to their complementary sequence present on the mRNA. As these fall into place, the tRNA drops off its amino acid, and leaves. The same happens again, and a polypeptide bond occurs between the two amino acids. This keeps happening, until a full polypeptide chain is made.

This polypeptide chain is processed into a mature protein.

k0ka [10]

The important suggestion that the nurse could give with a client that has ALS or also known as amyotrophic lateral sclerosis is that his or her illness is very important to be assess and to be monitored, in order to have a view and know the symptoms in which he or she exhibits, the diagnosis of his or her illness in which is really important in order to determine the best treatment to be applied to the individual. Tests are needed in monitoring, such as physical examination and test that involves of having to mimick the disease. It is important that the client should eat a wel balanced diet and to exercise regularly, in order to help in treating the disease.
