In natural selection what must be true of traits that are passed down through generationsal selection where do the alleles or tr
goblinko [34]
I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.

how many dna molecules would there be after four rounds of pcr if the initial reaction mixture contained two molecules?
Marat540 [252]
  1. Answer: 32 molecules of DNA would be after four PCR if the initial reaction mixture contained two molecules
  • After 'n' rounds of the polymerase chain reaction, it is feasible to produce 2 n DNA molecules from a single DNA template molecule (PCR). Therefore, 2 to the power 4  = 16 DNA molecules will be produced after 4 PCR cycles
  • If two molecules are doubled four times, 32 DNA molecules are created.

Explanation:

The PCR method is what?

The highly sensitive PCR method enables quick DNA amplification of a particular section. Using visual methods based on size and charge, PCR may detect and identify gene sequences by producing billions of copies of a certain DNA fragment or gene.

What does a PCR have to accomplish?

A given DNA segment can be quickly multiplied (amplified) into millions or billions of copies using the polymerase chain reaction (abbreviated PCR), allowing for more in-depth analysis.

What are the three main PCR steps?

For any DNA synthesis reaction, there are only three easy stages that must be completed: First, the template is denaturated into single strands. Next, primers are annealed to each original strand to synthesise new DNA strands. Finally, the new DNA strands are extended from the primers.
