8 0

Answer:

There will be 2 molecules.

Explanation:

Each PCR cycle replicates one DNA molecule. This cycle lasts about 2 minutes where the Denaturation (where the DNA double helix is ​​separated) phases occur, Bonding (where prmiets begin to establish complementary hydrogen bonds to the nitrogenous bases of the two DNA strands) and Synthesis (Where DNA polymerase begins to create new strands of DNA). Prior to the first round of PCR there was a DNA sample. However, after one cycle this sample was replicated, so the PCR reaction will follow with 2 DNA samples.

densk [106]
The double fortification process involves adding iodine and iron to salt. It is a method used to fight micronutrient deficiencies in developing countries. Iron and iodine are two of the most important micronutrients involved in cognitive function, maternal and infant survival and human productivity. This is a cost-effective method that ensures that the population receives these nutrients without having to change their eating habits.
