What Is Cloning? • A clone is a genetically identical copy of a living organism, such as the famous sheep ‘Dolly’ • Similar to an identical twin
DNA Empty DNA The Making of Dolly Cloning depends on DNA Step 1: Take the Nuclei out of a sheep egg Step 2: Transfer nuclei from the Mother Sheep Egg Mother’s Egg
Hello Dolly She was cloned using a cell taken from a healthy six-year-old sheep July 5, 1996, Dolly was born at the Roslin Institute, Edinburgh, Scotland
Cloning and the Cell Nucleus Its all about DNA
Nucleus Cloning Depends on DNA Chromosome
It’s all about DNA Good-Bye Dolly • At age 3 Dolly showed signs of premature aging. • Dolly died at 6 years old from progressive lung disease (symptom of old age) • Dolly’s DNA was already 6 years old when she was born - WHY?

More on Dolly and Cloning Dolly’s experimenters used 277 cloned embryos to produce one sheep, meaning 276 failed. How many failures will it take to produce a human Question ?

Some organisms are diploid - that is, they have paired homologous chromosomes in their somatic cells, and thus contain two copies of each gene. An organism in which both copies of the gene are identical - that is, have the same allele - is said to be homozygous for that gene. An organism which has two different alleles of the gene is said to be heterozygous
