Cloning animals - Dolly the sheep - GCSE Biology (9-1)

[@kalleruuska7163]

I wanted to know more about the Dolly sheep and this was the simplest and easiest explanation to understand. Thank you!

[@MrExhambio]

No problem

please i have a simple question, instead of the nucleus from 1 being put in the egg cell of 2 them into the surrogate 3, why didn't they put an egg cell of 1 straight into 3?

[@amanuelyirdawteshome6353]

Short but perfect

[@bennguyen1313]

Has the Yamanaka technique superseded the Dolly method (transferring the nuclear dna of a somatic cell to an unfertilized oocyte cell)? If not, when is one technique more applicable? Since four of Dolly's sisters didn't suffer the same fate... Dolly's early death at 6 years old, is often attributed to a viral-cancer, not related to the cloning procedure. But didn't Dolly also have advanced arthritis and CVD for such a young sheep? For example, some suggest that Dolly retained the epigenetic aging signature of the donor sheep.. her telomeres were much shorter than her chronological age would have predicted. Has the connection between cloning / teleomeres / and life-span been established? On the Life Scientific Podcast, Ian Wilmut mentions that sperm would normally signal to the egg to start dividing, but in this cloning technique, an electric shock to the egg is used! He also says that while all the genetic information came from sheep #1, there are factors in the egg (sheep #2) that change the expression of that DNA! However, I wonder how much influence the *environment* (sheep #3's horomones, stress, etc) also has over the DNA!

Hello Mr. Exham, i was curious if it is possible to crispr gigantism into the dna?

[@TheEarthCreature]

Can animals 1 and 3 be the same animal, theoretically? As in, could an animal birth its own clone?

Why did the biologist pick a sheep to clone?

[@Versatilad]

The link is missing! How was the egg fertilise?

[@rotarytexas3972]

It doesn't

[@leangsothyro5301]

why do we need 1 more sheep to put the the embryo in we can just out it in the second once

[@joshua5838]

Can we actually bring back extinct animals?

[@Wizlingss]

Yes unless if you have a reproductive cell sample of a female and male full preserved

This video precisely answered my questions about Dolly (^_^). BTW, can I know what app (or online website) was used for removing the background of the person speaking?? I really need if for my school project. Thank you!

It is called a green screen

just use something like greenscreen on zoom and like record it then use and editing software and add urself to the video.

@@gazey bro you make no sense i swear you literally said that you cant find this topic in your textbook which means that your following the wrong syllabus and if you take your igcse exams seriously like everyone else you would know not to waste time you never said nice video or this is intreasting literally what you said was why cant i find this topiic on my textbook....

why does it have to be an egg from another sheep?

[@farhanahmedheathland5923]

kzbin.info/www/bejne/Z3jPaIiHnayneaM

[@learav717]

Isn't it the same if you just use the egg cell of sheep number 1? Why was it needed to enucleated the egg cell of sheep number 2 when you could just use the full egg cell of sheep number one (which already has the dna of sheep 1) or enucleate the egg cell of sheep 1 and fuse it with the dna which would be extracted from another cell of sheep 1? Also why is it needed for the new cell, after its fused, to be implanted in a 3rd sheep?

[@BANANA-go5oq]

The egg cell has a random mix of genes due to meiosis, not the full genome.
