<span> polymerases, of which there are many. Understanding which types of polymerases perform which functions under which circumstances will clarify the complexity of this topic. The processes of transcription, making RNA from DNA, and replication, copying DNA from DNA, are major functions that require polymerases to link nucleotides into long chains. </span>
Answer:
Explanation:
a)Organ transplantation requires that the donor organism and recipient be genetically close so that the graft or transplant will not be attacked by the immune system of the recipient leading to rejection and damage. Squeaky is likely to be made up of a different genetic configuration compared to laboratory inbred FG426 mouse
b) ips (induced pluripotent stem cell) on the other hand can benefit squeaky since the cells are somatic cells such as B cells, Keratinocytes, neuronal progenitors cells, kidney and muscles gotten from the donor that are reprogrammed by reactivating silent genes through fusing of another different cell such as ES (embryonic stem cell) and introduction of some transcriptional factors such oct4, sox2,kf4, and k-myc leading to transcriptional activity and DNA methylation. This induced pluripotent stem cells can be grown into organ that can be transplanted to the recipient who was initially the donor of the reprogrammed somatic cells. Because it is from the host, the transplanted organ is not likely to trigger immune response compare to those grown from ES from other bred.
