细胞核
1. 细胞核：这样又造成了其它稳定的电子失去了与它配对的电子,变成了不稳定的奇数的电子,产生了自由基),它先侵蚀细胞膜(CELL MEMBRANE),既而进攻细胞核(CELL NUCLEUS),破坏核里的染色体(CHORMOSOME),即DNA,DNA被破坏以后,
1. The team created the beagles by infecting dog fibroblast cells with a virus that inserted the fluorescent gene into the cell nucleus.
2. The new technique seeks to condense and transfer only the donor's genetic material to a surrogate's egg instead of an entire cell nucleus.
3. The nucleus was then transferred to another dog's egg cell whose nucleus had been removed.
4. Researchers used a technology known as chromatin transfer, in which Nicky's DNA was transplanted into an egg cell whose nucleus had been removed.
5. The nucleus is replaced through a microscopic glass tube by the nucleus of a cell from the animal to be cloned.
6. \u0064\u0061\u006E\u0063\u0069\u002E\u0039\u0031\u0031\u0063\u0068\u0061\u002E\u0063\u006F\u006D
6. Each egg had its nucleus replaced by a whole human embryonic stem cell from a batch held at the UK stem cell bank.
