Embryonic stem cells are pluripotent cells that are derived from the inner cell mass of a blastocyst before implantation. These cells have potential of treating a wide range of diseases and conditions, which is attributed to the fact that they have; self renewal property meaning that they can ploriferate indefinitely, the cells also have the special ability to differentiate into cells with specialized characteristics and functions. In addition the cells are unspecialized and therefore they can give rise to specialized cells.
<span>The importance of embryonic stem cells lies in their versatility. These cells start off as a "blank slate" and thus can be modified and grown to turn into nearly any type of cell in the body. This means that, beginning with stem cells, one can regenerate whatever specific type of cell is needed to fight a certain disease or replace a damaged organ.</span>
Answer: The life cycle of plants is composed of sporophye generation and gemetophyte generation. They show alternation of generation in which gametophytr produce gametes that develop into sporophytic plant. Sporophye produce spores that develop into gametophyte plants.
They are useful as they can predict the genetic probability of a particular phenotype arising in a couple's offspring. In other words, it can tell you if you will or will not have a certain trait.
Answer: The correct answer is silent mutation . In this type of mutation there is no change in the phenotype of the individual which means there occurs a mutation where two different amino acid codes for the same protein .There are sequences present in the body where a point mutation occurs but the protein formed is still the same .If you will see the genotype you can easily observe that the amino acid sequence is different but the protein formed is same. Example AAA codes for lysine and the amino acid lysine is formed by AAG .
