Answer: When the protein for a particular gene is formed, the gene is expressed
Explanation:
Gene expression is the process in which the information from a gene is used for the synthesis of protein. The gene code for protein and the protein regulate the function of the cell in the body.
into RNA by the help of enzyme RNA polymerase. The next step is the translation in which the messenger RNA is decoded in the ribosome to produce a specific amino acid or the polypeptide chain that perform a specific function in the cell.
Bacteria and Fungi come under different categories; the former one is the prokaryotic cell while the latter one is Eukaryotic cells. Apart from this, there are many differences between them like bacteria need a host to live, and they can be autotrophs as well as heterotrophs, whereas fungi grow their own and are heterotrophs which depend on others for their food. Bacteria do not have nuclear membrane enclosing nucleus, while Fungi (eukaryotes) have well- defined nucleus surrounded by the nuclear membrane.
Answer: In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
Explanation:
Answer: Glial cells called ASTROCYTES help maintain the blood-brain barrier, whereas SCHWANN CELLS create the myelin that envelopes axons
Explanation: Glial cells are specialized cell that are found in both central and peripheral nervous systems, that surrounds the neurones, providing them with support and insulation. There are different types of Glial cells these includes:
- Astrocytes: they maintain the blood brain barrier.
- Schwann cells: create the myelin that envelopes axons of the peripheral nervous system neurones.
- satellite cells: These cells help regulate the external chemical environment of neurones.
- Microglia: they clean up cellular debris through phagocytosis.
- Oligodendrocytes: create the myelin that envelopes axons of the central nervous system
