Kloning: Mekanismer, eksempler og etiske overvejelser er en engelsk-opgave fra 2007 til 1.g el. lign., afleveret til karakteren 4. Fylder 4 sider (1.031 ord, ca. 4 min. læsning) og blev publiceret 14. januar 2010.

Denne opgave forklarer forskellige typer af kloning, fra naturlig aseksuel reproduktion til laboratorieteknikker som molekylær kloning og nuklear transfer. Den beskriver kloningen af Dolly the sheep og udforsker potentielle fordele samt etiske bekymringer ved kloning af dyr og mennesker.

There are different kinds of cloning. First there is the cells in our boudies, which is a clone of just one cell (the fertilised eeg, we originally came from).

Then there are the identical twins, because they are formed when a single embryo splits into two. The way plants can reproduce itself, is also a way of cloning. Then there is the way of cloning, where they are produced in the laboratories. It’s called ‘Molecular cloning’- and it is when you’re producing more genetic material from an original stretch of DNA. Last but not least, there is the ‘Nuclear transfer’, and that is a technique used to produce a clone from an adult cell (the way ‘Dolly’ the sheep was made).

Today, when someone talks about cloning, most people would think of a clone made in a laboratory. But with this, you could say that cloning is the way of making a genetically identical organsim through nonsexual means (without sex).

There are two ways of reproduction, the first is: sexual reproduction, and that is when the two sets of DNA (one from the father’s sperm and one from the mother’s

egg) is merging together, to produce a new offspring that’s genetically different from
