O QUE É UM CLONE? EXPLIQUE COMO OCORRE A CLONAGEM EM MAMÍFEROS.
Pavlova-9 [17]

Answer:

A clonagem é a obtenção de duas células idênticas com o mesmo código genético que o produto da reprodução assexuada.

Nos mamíferos, a clonagem ocorre através de células somáticas, onde há um núcleo doador e um oócito que se unem por meio de um choque elétrico, formando o embrião que resultará em um ser vivo clonado, um exemplo de essa era Dolly, a ovelha.

Explanation:

Na clonagem de mamíferos, o embrião é responsável por ter caracteres da ovelha doadora, ou seja, será a imitação do código genético desse animal que empresta a célula doadora ao úbere.
