It is carried in the form of a gene.
As "nurse" cells for neurons in the brain parenchyma, astrocytes are resident glial cells produced from neuroectoderm.
How astrocytes become pathological?
- Recent research has identified astrocytes as major disease-propagating agents in mutant human superoxide dismutase 1 (mSOD1)-mediated amyotrophic lateral sclerosis (ALS).
- However, due to the widespread expression of mSOD1 throughout the CNS of the investigated rodent models, in vivo examination of a specific astrocytic effect in amyotrophic lateral sclerosis has proven challenging.
- In order to understand how mutant astrocytes affect WT MNs and other cell types (microglia and astrocytes) in an in vivo environment, we transplanted SOD1(G93A) glial-restricted precursor cells into the cervical spinal cord of WT rats.
- SOD1(G93A) glial-restricted progenitor cells that were transplanted survived and successfully differentiated into astrocytes.

Answer:
Half.
Explanation:
Autosominal dominant trait are express are able to express themselves in the homozygous dominant as well as in the heterozygous condition. The X-linked recessive traits are mostly expressed in males since they have only one X chromosome. Female shows X linked recessive trait when her both X chromosome are affected.
The achandroplastic dwarf man with normal vision is married with a color blind woman with normal height. The mother is affected with vision, she definitely pass this trait to his son. The male is affected with achondroplastic (may be homozygous dominant or heterozygous) and the female is normal (homozygous recessive). The probability can be calculated including both the achandroplastic and vision trait. Half of the males are color blind with normal height (multiplying the probability of vision and achandroplatic trait).
Answer: In the field of molecular biology the correct sequence of events are as follows:
1. Gregor Mendel proves the Laws of Inheritance in 1865.
2. Friedrich Miescher conducted experiments to identify nuclein as the building blocks of life in 1869.
3. James Watson and Francis Crick presented a model of DNA in 1953.
4. Frederick Sanger developed a method for sequencing DNA in 1977.
Answer:
The main components of the cytoplasm are cytosol (a gel-like substance), the organelles (the cell's internal sub-structures), and various cytoplasmic inclusions. The cytoplasm is about 80% water and usually colorless.
