The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.
Answer:
1. Number of DNA molecules after 30 Cycles of PCR = 1.02 x 10^9
2. No. of mutant DNA molecules = 1.07 x 10^9
Explanation:
1. You just have to take the exponential of 2 to the power of the number of PCR cycles (2^n)
2. All copies were normal at cycle 10 that are about 1024 copies. At cycle 11 single point error, all further copies are mutated.
