Difference between expression vector and cloning vector
olga_2 [115]


Cloning vectors are the DNA molecules that can carry a foreign DNA segment into the the host cell.The vectors used in recombinant DNA technology can be plasmids, cosmids, bacteriophages etc. 

Plasmids: Self replicating, circular,  extra chromosomal DNA present in bacteria. Plasmids have only one or two copies per cell.

Bacteriophages: Virus infecting bacteria. Bacteriophages have high number per cell, so their copy number  is also high in genome.

Cosmids: Hybrid vectors derived from plasmids which contain cos site of lambda phage.

Feature required to facilitate cloning into vector: Origin of replication, Selectable marker, unique restriction sites.
The purpose of cloning vector is often to make numerous copies of the inserted gene.


Expression Vectors: The cloning vector containing suitable expression signals to have maximum gene expression, is called expression vector. 
The following expression signals are introduced into gene cloned vectors to get maximum expression:

Insertion of a strong promoter.

Insertion of a strong termination codon.

Adjustment of distance between promoter and cloned gene.

Insertion of transcription termination sequence.

Insertion of a strong translation initiation sequence.

The radius of a circle is 4 feet. What is the area of a sector bounded by a 45° arc?
DIA [1.3K]

Answer:

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2

Step-by-step explanation:

Given

Radius, r = 4ft

Angle, \theta = 45

Required

Calculate the area of the sector

When angle is given in degrees, the area of sector is calculated as thus;

Area = \frac{\theta}{360} * \pi * r^2

Substitute\ r = 4\ and\ \theta = 45

Area = \frac{\theta}{360} * \pi * r^2 becomes

Area = \frac{45}{360} * \pi * 4^2

Area = \frac{45}{360} * \pi * 16

Area = \frac{45*16}{360} * \pi

Area = \frac{720}{360} * \pi

Area = 2 * \pi

Area = 2  \pi\ ft^2

The above is the area in terms of π

Solving further.... (Take π as 3.14)

Area = 2  \pi\ ft^2 becomes

Area = 2 * 3.14\  ft^2

Area = 6.28\  ft^2

Hence, the area of the sector is

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2
