A. The oceans have a major effect on climate around the globe.
Electrical energy is energy derived from electric potential energy or kinetic energy. So D would be the best answer
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.
Answer:
The correct answer will be option C- A structure upon which proteins are assembled.
Explanation:
A ribosome is a complex molecule machine formed of proteins and rRNA molecules which acts as a site for the synthesis of the proteins.
These ribosomes are present in the cell as a free entity suspended in the cytosol or attached to the endoplasmic reticulum.
Each ribosome is made up of a large and small component which translates the information coded in the mRNA in the form of codons to amino acids which join to form proteins.
Thus, option- C is the correct answer.
