Dolly the Sheep

Dolly the Sheep | Biology Education | Scoop.it
Dolly (July 5, 1996 - February 14, 2003), a ewe, was the first mammal to have been successfully cloned from an adult cell. She was cloned at the Roslin Institute in Midlothian, Scotland, and lived there until her death when she was six years old. Her birth was announced on February 22, 1997. The sheep was originally code-named "6LL3". The name "Dolly" came from a suggestion by the stockmen who helped with her birth, in honor of Dolly Parton, because it was a mammary cell that was cloned. The technique that was made famous by her birth is somatic cell nuclear transfer, in which a cell is placed in a de-nucleated ovum, the two cells fuse and then develop into an embryo. When Dolly was cloned in 1996 from a cell taken from a six-year-old ewe, she became the center of much controversy that still exists today.
Hannah Govan's insight:

Dolly was the first successful cloned mammal. If they can already clone sheep, do you believe someday scientists will successfully clone a human? If so, is it morally appropriate to do so? List 3 negatives and positives of human cloning.

Eukaryopolis - The City of Animal Cells: Crash Course Biology #4 - YouTube

Hank tells us about the city of Eukaryopolis - the animal cell that is responsible for all the cool things that happen in our bodies. Crash Course Biology is...
Hannah Govan's insight:

This video identifies the key structure components of an animal cell. Before you view this clip, try to label the animal cell. Watch the clip then try to label the cell again. How many components did you know and how many new components did you learn?
