An enzyme, which cleaves DNA after identifying a specific sequence of DNA is known as a restriction enzyme. The restriction enzymes are regarded as molecular scissors. The restriction enzymes are used by scientists to cleave a single gene from a bigger DNA piece that is, a fragment of foreign DNA and is spliced into a phage genome with the help of DNA ligase and restriction enzyme.
The packaging of recombinant phage DNA is done in vitro and is permitted to infect a bacterial cell. The infected bacteria generate novel phage particles, each comprising a foreign DNA.
They are urinary and reproduction!
This study is important as the latest and no specific numerical values identified for bovine skin. According to previous studies, in vitro experiments were performed on the skin of animals such as mice, cows, rabbits. The important parameters
I believe that I know what you are talking about however a better layout or source would be nice.
3:I’m sorry I’m not really sure how to answer this one but I’m going to assume that you mean from dark to light. So they liked this time period because the trees were darker due to pollution, this made the darker moths survive from predators while the lighter color moths would be eaten, over time, natural selection would do its course and the whole population of moths would be dark.
4:Well I kind of already answered this but the majority of them were dark because the lighter ones would not be camouflaged therefore making them be easier target for predators and makes the darker moths breed out the lighter ones.
5:Well giraffes cannot live without food so the giraffes with shorter necks would slowly die off making it so only the long necked one would be able to reproduce with babies which would also have long necks, over a long course of time, the shorter necks would be completely gone.
6:Well I wouldn’t say they “grow” longer necks. It’s more like genetic mutation made it so random giraffes would get longer necks then others, since giraffes live in an environment where they have to have long necks only the giraffes with that genetic mutation would survive, and as a said, the longer neck giraffes could only breed with the other Long necked giraffes cause those are the only ones that could survive.
