After 12 pcr cycles how many dna strands would be available?

PCR or polymerase chain reaction refers to a procedure used to exponentially increase a particular target DNA sequence, permitting the sequencing, isolation, or cloning of a single sequence in many.  

The number of double-stranded DNA segments is doubled in each of the cycles so that after n cycle one will have 2^n copies of DNA. For example, after 10 cycles one will have 1024 copies of DNA strands. Therefore, after 12 cycles of PCR one will have about 4096 copies of DNA strands.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
