Question

Could an animal be cloned from a juvenile animal?

Dotty the sheep was cloned from a 6 year old sheep. If the donor of the somatic cell had been younger, would she have longer chromosomes? Furthermore, would the experiment have been successful? I haven't found much information on the requirements for a somatic cell to be eligible for cloning.

I'm asking this because I have a debate on Animal Cloning in Science Class on Thursday, and I would like to know this information so the opposing side (For Animal Cloning) cannot compose a strong rebuttal.

Answer 2

@whiteowl13 I don't know what@princeshoalib is posting, but here is the deal:

First, Dolly was successful. The issue is that as DNA is replicated in Eukaryotes the ends of the chromosomes are lost, so each replication shortens the chromosome. This is thought to be part of the issue with aging. Because Dolly was cloned from an older sheep, the chromosomes were already shorter than that of a young sheep. We expect, and I believe did see, Dolly suffering from apparent age related issues that were not normal for her age, but more typical of the age of the source of the cloned DNA.
