Question

The famous experiment preformed by Briggs and Kind in 1953 using somatic cell nuclear transfer tested for genomic equivalency demonstrated that:

a)frog oocytes when fertilized develop into adult frogs
b)the nuclei of an embryo is genetically distinct from a skin cell
c)the cytoplasm of skin cells of an albino frog contains material for the develop,ent of an embryo
e)skin cell genetic material can drive the development of an organism

Answer 1

The experiment by Briggs and Kind demonstrated that the genetic material from a skin cell can drive the development of an organism through somatic cell nuclear transfer, confirming that all cells in an organism have the same genetic information.

Step-by-step explanation:

The famous experiment performed by Briggs and King in 1952, as well as later work by John Gurdon and Shinya Yamanaka, demonstrated the principle of genetic equivalency within multicellular organisms. In their experiment, they used somatic cell nuclear transfer, a technique where a diploid nucleus is transferred into an enucleated egg. This process effectively creates a zygote that is genetically identical to the donor of the nucleus. The resulting entity can then develop into an adult organism, proving that skin cell genetic material can drive the development of an organism. This is because all cells in a multicellular organism contain the same genome, enabling the possibility of reproductive cloning. The cytoplasm of the egg cell is necessary for early embryonic development, but the actual genetic information comes from the nucleus, whether it is from a normal zygote or a zygote created through somatic nuclear transfer.
