DNA supercoiling means under or over winding of the DNA strand and basically is to become more condensed and more organized. Supercoiling is very important as it compacts the genetic code and as if that was not enough supercoiling also regulates and oversees the access the the genetic code.
Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.
C
As the cap helps it to move around while the tail prevents enzymes from eating the RNA
Cerebral cortex is the area of human cortex that is different from the brains of other animals. Cerebral cortex functions is responsible for the thinking and taking in information in order to make a necessary action based on the perception that it receives. Cerebral cortex are divided into 4 lobes with a different function namely; frontal, temporal, parietal and occipital which are converts the sensory information that you receive.<span />
