What is micro injection? How it is helpful in recombinant DNA technology?

Solution:

Microinjection is glass micropipette that facilitate injecting microlitres of cell’s fluid into other recipient tissues so as to introduce new genes in the genome of the organism.

 

Microinjections helps in recombinant DNA technology in following ways-

  • It helps in producing transgenic organism that are genetically modified.
  • They help in introducing better quality breeds in the inferior quality breeds of the plant that in turn facilitate better outcome.
  • By the help of microinjections assure the precision of delivery and efficient transduction process.

At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north. The north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points above the horizontal. The horizontal component of the earth’s field is measured to be $0.16 \mathrm{G} .$ Specify the direction and magnitude of the earth’s field at the location.At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north.
