Outside the plasma membrane there is presence of glycoprotein which is a series of polysaccharides to form the cell coat and is used for ID or cell recognition. Each individual has a unique special code for the glycoprotein.
The nucleus directs all activities that happen within the cell and contains the cell genetic material (DNA).<span> The nucleus gives the signal to the cell to grow, divide and/or make proteins. </span>
Symbiotic Relationship.
Hope this helps.
No never ! Virus will never have a cell wall but it does have a protein capsule !
Answer: Germline mutation
A germline mutation is a mutation in the fully developed germ cells (sperm and ovum). These defective mutated cells fuse to form zygote. The zygote rapidly produces all somatic and germline cells in the offsprings which are also mutated. Therefore, mutation is transmitted from parents to offsprings. Cystic fibrosis is a result of germline mutation. This disease is hereditary in nature passes from parents to the offsprings. If a child receives CFTR (cystic fibrosis transmembrane conductance regulator) mutated gene from both the parents than the child will be affected by the symptoms of this disease. If the child receives a single copy of CFTR gene from either of the parent than the child will be the carrier of disease.The mutated gene may be present in the germline cells of the parent or on all the body cells.
