define vector & explain different types of vector
Answers
Answer:
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). ... The four major types of vectors are plasmids, viral vectors, cosmids, and artificial chromosomes.
Types of vectors :
- Equal vectors
Two vectors are said to be equal if they have equal magnitude and equal direction.
- Negative vector
Two vectors having equal magnitude but opposite in direction are known as negative vectors.
- Position vector
The vector which represents the magnitude and direction of the particle from the origin is known as position vector .
- Displacement vector
The vector which represents the magnitude and direction of the displacement of the particle is known as displacement vector.
- Unit vector
A vector having unit magnitude and direction is same as that if given vector is known as unit vector.
