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.
Answer:

Answer:

Answer: Both the mouse and human beings are encoding the proteins having similar functions.
Explanation:
The CFTR gene in the mouse and CFTR gene in the human beings encode proteins that perform similar function,this is so because if the results are same then it means that both mouse and human beings are encoding the protein that have similar function.
Option A is incorrect because both humans and mouse are eukaryotes so they have introns and because of that even if the gene sequences are different they can still encode protein.
Option B is incorrect because amino acid sequences can be similar inorder to have the similar function. If glutamic acid is replaced by aspartic acid, it won't have different function the function will remain same. So, identical amino acid sequences are not required. They can be similar too.
