In humans, the disease cystic fibrosis is caused by a recessive allele for a gene that encodes a specific type of channel protein. Using C as a “normal” allele for the disease, under what conditions is it possible for a child with cystic fibrosis to have biological parents who do not have the disease? Both parents have the genotype Cc It is not possible for this to occur Both parents have the genotype CC

Tissue regeneration & repair

Tissue regeneration involves the restoration of tissue components by regrowth of damaged tissues. In contrast, tissue repair involves patching of injured tissue rather than restoring it. It is the proliferative capacity of the cells that decides the amount of regeneration against the repair that would occur in the tissue. Both regeneration and repair depending on the duration of the injury and response to the inflammation.
