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.

Evidence that supports the prokaryotic origins of mitochondria and chloroplasts are all of the following except __________.
hodyreva [135]

Your question was incomplete (please check below the full content). The evidence that supports the prokaryotic origins of mitochondria and chloroplasts do not include multiple DNA copies associated with inner membranes.

<h3>What is organellar DNA?</h3>

The organellar DNA is the genome contained within mitochondria and chloroplasts, which is independent of nuclear eukaryotic DNA.

The organellar DNA contains multiple DNA molecules, which are found in association with the inner membrane, ant is not found in prokaryotic life forms.

The complete question in this case is: "Evidence that supports the prokaryotic origins of mitochondria and chloroplasts are the presence of mitochondria, a eukaryote engulfing prokaryotic photosynthetic cells, and non-photosynthetic eukaryotes, EXCEPT."

The endosymbiotic theory states that mitochondria and chloroplasts evolved from prokaryotic microorganisms that entered into a primitive eukaryotic cell.

This theory is supported by certain features of mitochondria and chloroplasts such as a similar size to prokaryotes.

In conclusion, evidence do not include the arrangement of the organellar DNA.

Up to what concentration is carbon dioxide a limiting factor for photosynthesis in low light intensity?
Mariulka [41]

Answer:

<u>Carbon Dioxide limits photosynthesis at a concentration of around 400 ppm (ambient concentration) in low light.</u>

Explanation:

Limiting factors affect the photosynthetic rate, decreasing the potential amount of carbohydrate made via photosynthesis. Carbon dioxide is essential to this form of biosynthesis- it provides the inorganic carbon that is integrated into carbohydrate molecules.

Carbon dioxide is typically present in the atmosphere at concentrations of 0.04%. Light intensity typically cause stomata to open, and increase CO2 uptake. Higher concentrations of CO2  up to 0.1%, cause dramatic increases in the photosynthetic rate.

Low light, thus means less stomatal opening, and less CO2 uptake. As low light intensity can be limiting, it lowers the concentration of Carbon dioxide at which the rate becomes constant.
