human +chimpanzee=humanzee

human+chimpanzee=humanzee
one of the achievements of BIO TECHNOLOGY using DNA is cloning. it is of 2 types
1.molecular cloning
2.animal cloning
now we ll see about animal cloning.the steps involved in cloning are
1.isolation of a haploid cell ie an egg cell. it is ennucleated ie its
nucleus is removed
2.then isolation of a somatic cell ie a cell from any part of the body
is also ennucleated and its nucleus is inserted into the ennucleated
haploid
now the fusion product is kept in a surrogate mother and a clone is formed
man and chimpansees have 95% similarity in DNA sequences and 99% in
the exons of the DNA genes
thus by using the above method of biotechnology involving the DNA
genes HUMANZEE is created. it is also called CHUMAN OR MANPANZEE
similarly potato and tomato are biotechnologised to form POMATO and
tiger and lion genetically engineered to make TIGON
with the advent of biotechnology and dna , many unbelievable events are occuring in the world..

a medicine which cured a disease yesterday, cant cure it today why?

VISIT http://www.indiareviewchannel.com/products/Health-Beauty-reviews-52.aspx FOR HEALTH PRODUCTS a medicine which cured a disease earlier couldnot do it now.why
it can be explained by DNA BIOTECHNOLOGY...
such a medicine resistance in the disease causing pathogens is known
as TRANSFERABLE ,EPISOMAL OR INFECTIOUS DRUG RESISTANCE
the plasmid contains RTF resistant transfer factor along with a
resistance determinant r. the whole plasmid is called R FACTOR
such an R FACTOR is transferred by the methods of gene transfer such as
1.transformation
2.transduction
3.conjugation
as a result ,the donor bacteria makes the recipient resistant to the medicine and the awake goes on.
such an incidence of resistance is proportional to the use of antibiotics because they 1.destruct the normal sensitive flora
2.selection pressure by the drug
so what is the bio chemical basis of such a medicine resistance . it is 1.decreased permeability to the medicine
2.alternate metabolic pathways and
3.productions of enzymes inactivating the medicine
thus if a bacterial strain is resistant to a medicine it transfers the resistance to other bacteria and the chain goes on.....
so how to stop this chain reaction.
will the bacteria keep on become resistant to the medicine
. THE ANSWERS WILL BE IN MY UPCOMING POSTS...

bacteria are very very funny why?

bacteria are very funny . why
GENE transfer by the method of conjugation.
this is a special character of bacteria.gene transfer occurs in bacteria by many methods.they are
1.transformation
2.transduction
3.conjugation
the conjugation method of gene transfer in bacteria is the fun factor here.
the male bacteria replicates its extrachromosomal ie the plasmid.the fertility factor F FACTOR in it forms the conjugation tube and finally a copy of the plasmid is given to the female bacteria via the conjugation tube
the fertility factor is responsible for the gene transfer from male to female
WHAT IS FUNNY HERE IS ,WHEN THE PLASMID ALONG WITH THE F +FACTOR IS
TRANSFERRED FROM THE MALE TO FEMALE,THE LATTER IS CONVERTED INTO THE
FORMER. YUP
FEMALE BACTERIA BECOMES MALE.FUNNY BACTERIA .
ARENT THEY ??
