During symmetrical division, are produced.

During the division of the stem cells, mainly two types of divisions takes place. These divisions are symmetric and asymmetric. In the asymmetric division, the cells are divided into two cells, these two cells have two different fates and they grow and divide in different aspects.

In the symmetric division, the stem cells are divided into two similar types of cell. The cells have the similar fates and they grow and divide in a similar fashion.

So, the given blank can be filled with similar daughter cells.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.
