In frogs, when the nucleus of an intestinal cell of a tadpole is transferred to an egg whose nucleus has been removed (nuclear transplantation), some of the eggs will develop into normal tadpoles. This demonstrates that .

This demonstrate that the nuclei from specialized cells still held the potential to be any cell despite its specialization.

Explanation:

Sir John Bertrand Gurdon can be described to have developed more on nuclear transplantation, the technique used to clone organisms and to create stem cells.

He made the conclusion after the demonstration that the nuclei from specialized cells still held the potential develop and be any cell despite its specialization.

The question above showed us that the intestinal cell nucleus of a tadpole was transferred to an unfertilized enucleated egg cell and few uninjured grew to become develop into normal tadpoles.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
