What is scalar and vector class 11?
Hint: A scalar quantity is any physical quantity that has only magnitude but no direction. A vector quantity has both magnitude and a specific direction. Therefore, in essence, a scalar quantity is nothing but a vector quantity with no specified direction.
What are vectors in molecular biology?
In molecular cloning, a vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated and/or expressed (e.g., plasmid, cosmid, Lambda phages). A vector containing foreign DNA is termed recombinant DNA.

What is vector explain?
vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction, it does not have position.
