Polymerase chain reaction (PCR) is a technique used to amplify (copy) DNA. Suppose a single, linear molecule of double‑stranded

DNA (dsDNA) is amplified by PCR. After one PCR cycle, how many molecules of dsDNA will there be?

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.

Explain why DNA is called a molecular clock.
hammer [34]

The molecular clock is a figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged. The biomolecular data used for such calculations are usually nucleotide sequences for DNA or amino acid sequences for proteins.

Daniel [21]
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
