What is the signal speed if the thickness of the myelin sheath is halved but no other changes are made to the axon?

Biology

blagie [28]1 year ago

Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.so the signal speed might slow down as it got halved

Myelin is the insulating layer, or sheath that forms around the nerves, including those in the brain and in the spinal cord. It is made up of some  protein and fatty substances. This myelin sheath is allows electrical impulses to the transmit quickly and efficiently along with the nerve cells. If the myelin is damaged, these impulses slow down.

Myelin is repaired or replaced by the special cells in the brain called as oligodendrocytes. These cells are made from special type of stem cell that found in the brain, called as oligodendrocyte precursor cells (OPCs).

After doing a genetic analysis on your respective _______, you and your roommate learned that you shared the same maternal ances
Norma-Jean [14]
MRNA is a short lived form of genetic information that is used in transcribing the genetic information, hence it is not very useful for analysis since it is fragile and wrong transcriptions happen quite often. SNPs (Single Nucleotide Polymorphisms) are a form of genetic mutation; they are more frequent than most other mutations since a single transription error may lead to this. While SNPs are important in genetic analysis and getting information about causes of disease, they are not very helpful in determining your maternal lineage. Similarly, while nuclear DNA contains a large portion of our genetic information, half of it is from our fathers and half from our mothers, so the analysis becomes hazy very soon. Mitochondrial DNA instead is directly passed down from mother to her offspring since the embryo contains only the mitochondria of the ovary. Thus, studying differences between mitochondrial DNA, one can gain information about his maternal lineage and go back to Mitochondrial Eve, the person from which all living persons have gotten their mitochondria from. Thus, the correct answer is c.

Why does a frameshift mutation usually cause more effects during protien sythesis than a point mutation
Levart [38]

Frameshift mutation affects codons downstream the point of mutation. The previous order of 3 nucleotide- sequences (codons) is consequently changed. This, therefore, changes the protein coded by the mRNA transcribed by the mutated DNA region. Frameshifts are mostly due to insertion or deletion mutations.
