In active transport, molecules can be moved against their concentration gradient, what is required for this

Biology
1 answer:
babymother [125]3 years ago
6 0

Answer:

Energy (in the form of ATP)

Explanation:

The main difference between active transport and passive transport is that active transport needs the energy to work. Active transport also moves molecules against the concentration gradient, kinda like a pump. This pump will need energy in the form of adenosine triphosphate (ATP) to keep it working. Adenosine triphosphate will be broken down into adenosine diphosphate (ADP). The energy from the breakdown reaction will be used by the pump.

Nowadays, different countries are constantly emerging and expanding their liabilities which may include the field of medicine. The disease that is being discussed by the instructor that is considered nearly eradicated is probably the measles. This disease is caused by Paramyxovirus which is a major respiratory pathogen among infants and young children. Measles is also known as “rubeola virus”, an acute, highly respiratory symptoms and a maculopapular rash that affects the mouth, head, body and extremities. It begins with the appearance of Koplik spots which may end up to some complications like symptomatic encephalitis and subacute sclerosing panencephalitis(SSPE). In order to prevent this type of disease MMR(Measles, Mumps & Rubella) Vaccine is needed. According to some of the reports, it is still common to some of the countries, but WHO campaigns to eradicate the disease worldwide by the year 2020.

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.
