Explanation:
Psi packaging Element is a cis-acting RNA element identified in the genomes of the retroviruses Human immunodeficiency virus (HIV) and Simian immunodeficiency virus (SIV) It is involved in regulating encapsidation of the retroviral RNA, an essential step in replication.
B: They occur more quickly than reactions without enzymes
Conservationists occasionally light forests on fire to control wild fires. By occasionally burning material (like leaves, branches, etc), those materials cannot build up and cause large and uncontrollable fires later.
The equation which is correct according to ohm’s law is v = ir which is denoted as option D.
<h3>What is Ohm’s law?</h3>
This states that the voltage across a conductor is directly proportional to the current flowing through it.
This is deduced as V ∝I where v is voltage and I is current.
V = IR
