sergejj [24]

The pronunciation of the anatomic structure that conducts impulses to and from the brain and initiates reflex action to sensory information is the spinal cord.

  • The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lowers it back together.
  • Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
  • The protection of the spinal cord, nerve roots, and many internal organs are the spine's three primary tasks. To keep your body upright, give it balance and structural support.
  • Enable fluid movement. The spinal cord is surrounded by cerebrospinal fluid (CSF), which is additionally protected by three layers known as the meninges (dura, arachnoid, and pia mater). The spinal column, which consists of 33 bones known as vertebrae, houses the spinal cord.

Answer:

Both gene expression and DNA micro array study about the expression of gene during different stages of development.

Explanation:

The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.  

DNA microarray  assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.
