Answer:
Polymerase chain reaction (PCR) test is used to duplicate traces of DNA from any living form, for identification purposes. The correct sequence is 1, 3, 2; based on the options given.
Explanation:
The steps to be followed for the PCR procedure are:
<em>Denaturation</em>
Option 1. Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links
<em>Annealing</em>
Option 3. Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.
<em>Elongation</em>
Option 2. Incubate at 72°C to promote the extension of the DNA strands, actually extending them.
The number of protons,neutrons,electrons, the way the are classified (earth metal, noble gas,meteoroids) and also the way they react.
Answer:
The answer is parable A
Explanation:
Its the only one that made sense in my eyes some of them didn't even match the topic.
I think it’s DNA molecule
Answer:
Autotroph is an organism that produces complex compound on itself and heterotrophs are the one which cannot produce its own food.
Explanation:
- Autotroph are the primary producer that can create the complex compound required for their development from the simple substances that are easily found in the environment.
- Autotroph uses energy from the inorganic chemical reactions and light.
- Heterotrophs depend upon the other nutrition sources because they cannot produce on their own.
- Heterotrophs are consumer where as autotrophs are producer in teh ecosystem.
