BiologyCells, tissues and organsGCSEAQA Created by: tonisha_Created on: 26-02-23 14:31 What two ways can we clone animals? embryo transplants adult cell cloning 1 of 32 EMBRYO TRANSPLANTS ---------------------------- First you start with a ____ and _____ cell? sperm and egg 2 of 32 From the organisms with _____ ____? desired characteristics 3 of 32 Then we produce a ______ egg? fertilised 4 of 32 We then allow it to develop into? an early stage embryo 5 of 32 However we must ensure none of the cells? specialise 6 of 32 We then use a ____ _____ to _____ the embryo? glass rod to split the embryo 7 of 32 We then transplant the embryos into? the host mothers 8 of 32 When the animals are born? they will be identical clones 9 of 32 PROBLEM --------------------- Since we start with? sperm and egg cell 10 of 32 We cannot be sure if? offspring will have desired characteristics 11 of 32 ADULT CELL CLONING ------------------------------- First remove a ______ from the animal we want to _____? cell clone 12 of 32 For example? skin cell 13 of 32 We will then remove the ______ from that ____? nucleus from that cell 14 of 32 This contains the _____ ______ from the animal? genetic information 15 of 32 We then take an _______ ____ from the same ______? unfertilised egg from same species 16 of 32 And remove? the nucleus from the egg 17 of 32 What do we do with the nucleus from the body cell? insert that nucleus into empty egg 18 of 32 What do we then give the egg cell? an electric shock 19 of 32 This allows the egg to start to? divide and form an embryo 20 of 32 These embryo cells will contain the______ genetic information as the adult _____ cell we _______ with? same body started 21 of 32 Once the embryo is a ? ball of cells 22 of 32 It is then _____ into the _____ of an adult female of that organism to continue its _____? then inserted into the womb of an adult female of that organism type of continue its development 23 of 32 The host mother will then? give birth to the clone 24 of 32 BENEFIT -------------- Since we are cloning from an adult, we know? that the offspring will have the desired characteristics 25 of 32 PROS ---------- It could lead to _____ and ______ understanding of animals? greater and deeper 26 of 32 It could help preserve? endangered species 27 of 32 CONS ------------- We have a reduced? gene pool 28 of 32 This means a pathogen? could wipe them all out 29 of 32 Clones may not be as? healthy 30 of 32 Humans may? be cloned in the future 31 of 32 Which could result in them having? disabilities 32 of 32
