In the formation of transgenic animals, DNA is usually inserted into eggs or embryos. If some cells of the embryo do not receive

the introduced DNA, the result is an organism with cells of different genotypes; the organism is known as what?

Answer:

The correct answer will be- Chimera

Explanation:

A chimera is an organism which is composed of cells with different genotypes.

The genetic chimera is produced during the formation of the transgenic organisms mainly animals when every cell of the growing embryo does not receive the introduced genes. This results in the formation of two or more zygotes which when merged form genetic chimera.

Thus, a chimera is the correct answer.

Darwin realized that the often exquisite fit of species to their environment is primarily the result of
bagirrra123 [75]
Natural Selection.
An easy and important way to remember this is by thinking of a species - let’s say a bright white moth. For ages, these moths have survived beautifully, matching perfectly with the white tree bark they live on, until one day, a smoky building begins pumping its soot into the air. This air begins to change the color of the tree bark to black and the once hidden white moths are now plainly visible to birds who eat them easily. Fortunately, every now and then a moth is born who is darker than the rest - black as soot even. And so, the birds keep eating the white moths but missing the soot-colored ones. As time goes by, the soot-colored moths produce more and more similarly colored moths, who are well hidden from the birds AND after enough time, the only moths that remain are soot-colored. This is why so many species “fit” exquisitely into their environment. They have ALL adapted in some way similar to the soot-colored moth.

Many mutations have been identified in the lac operon. A particular mutation in the CRP gene make the CRP protein bind to the Pl
maksim [4K]

Answer:

a. + glucose, + lactose  = On

b. - glucose, - lactose  = Off

c. + glucose, - lactose  = Off

d. - glucose, + lactose = On

Explanation:

Lac operon has both types of control, repressible and inducible.

Whenever glucose level is low in the cell, an enzyme known as adenylyl cyclase raises the level of cAMP which forms a dimer with CRP protein and they both act as activator of lac operon and cause expression.

Apart from this, when lactose is present in the cell, β-galactosidase enzyme metabolizes lactose to form allolactose which causes allosteric repulsion in the lac repressor and causes its removal from the operator. As soon as repressor is removed lac operon gets activated.

In wild type lac operons, the expression of lac operon occurs when glucose level is low in the cell and lactose is present but in this mutant presence or absence of glucose will not make a difference because CRP will bind Plac promoter independent of cAMP level i.e. activator CRP will work even in high glucose concentration. If lactose is present then lac operon will always express so in option 'a & d' lac operon will express but in option 'b & c' it will not express.
