You can leave the chicks with the mother but it will only last 4 to 8 weeks. Usually, it's the mother hen who wants to wean them and get back to her flock. In warm weather, you don't really need a heat lamp, but get a secure pen and chick starter until they're 20 weeks old.
The process of putting a gene into a vector is called molecular cloning or gene cloning. Most vectors are based on plasmids, which are small circular sequences of DNA that occur naturally within bacteria. Plasmid vectors can accept a few genesâ worth of DNA.o introduce foreign DNA into a circular vector, scientists carry out a three-step process: 1  Cutting out the gene. 2  Scientists first remove their gene of interest from the DNA sequences on either side of it.
Transgenesis can be facilitated by liposomes, enzymes, plasmid vectors, viral vectors, pronuclear injection, protoplast fusion, and ballistic DNA injection. Transgenesis can occur in nature. Transgenic organisms are able to express foreign genes because the genetic code is similar for all organisms. This means that a specific DNA sequence will code for the same protein in all organisms. Due to this similarity in protein sequence, scientists can cut DNA at these common protein points and add other genes.
