Notes

My name is Magdalena Knap. I'm studying biotechnology at the silesian University of technology in Gliwice.


I would like to tell about the proccess what is cloning. This topic is connect with the subject who I studying

first I tell you what is cloning , and where is the mostly use, next what is purpose the use of cloning.
the next stage of presentation will be show first cloned mammal
sheep dolly
at the end i tell about adventages of clonning


1 In biology cloning is the process of producting exact copy of the parents organism
which contain the same genetic information .The term clone, invented by J. B. S. Haldane, is derived from the Ancient Greek word klōn, "twig". Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms
2 Cloning is the most frequently used in creation of animal husbandry(hodowla zwierząt ) ,which are not at risk of disease, and crate transgenic animals or
restoring extinct species

In connection with the subject I would like to tell you about the first cloned mammal.
Dolly was a female domestic sheep. Successfully cloned from an adult somatic cell. Dolly was formed by taking a cell from the udder of her 6-year old biological mother

Dolly's embryo was created by taking the cell and inserting it into a sheep ovum. It took 434 attempts before an embryo was successfull.
Dolly lived her entire life at the Roslin Institute in Edinburgh. She produced six lambs in total .Her first lamb, named Bonnie, was born in April 1998 .
dolly name comes from the singer Dolly Parton, is an allusion to her breast, because dooly was created from the mammary gland.

at the end I would say about the adventages of cloning.
the creation of transgenic animals, allows save the human life , because they blood and organs can be transplanted

cloning allows on increasing the number of animals that are threatened with extinction

Thank you for your attention
