Endocytosis brings molecules in
Exocytosis takes molecules out

The organism under study, which will be used to donate DNA for the analysis, is called the donor organism. The basic procedure is to extract and cut up DNA from a donor genome into fragments containing from one to several genes and allow these fragments to insert themselves individually into opened-up small autonomously replicating DNA molecules such as bacterial plasmids. These small circular molecules act as carriers, or vectors, for the DNA fragments. The vector molecules with their inserts are called recombinant DNA because they consist of novel combinations of DNA from the donor genome (which can be from any organism) with vector DNA from a completely different source (generally a bacterial plasmid or a virus). The recombinant DNA mixture is then used to transform bacterial cells, and it is common for single recombinant vector molecules to find their way into individual bacterial cells. Bacterial cells are plated and allowed to grow into colonies. An individual transformed cell with a single recombinant vector will divide into a colony with millions of cells, all carrying the same recombinant vector. Therefore an individual colony contains a very large population of identical DNA inserts, and this population is called a DNA clone. A great deal of the analysis of the cloned DNA fragment can be performed at the stage when it is in the bacterial host. Later, however, it is often desirable to reintroduce the cloned DNA back into cells of the original donor organism to carry out specific manipulations of genome structure and function.
Answer:
From the experiments that have been carried out, it is known that Mendel's theory of segregation can be proven even though the probability is true that the value is not 100%. By using the calculation of the Chi quare equation from the results of existing experiments, it has been found that the theory is compatible with the experiments.
Of all the possibilities of coin tosses in the second experiment, the result is that the probability of a coin not being equal to the "coin" is greater than the possibility of a coin equal to "coin". If we relate to Mendel's theory of cell segregation, then the possibility of random gene descent is correct, but this experiment is not necessarily appropriate because it is done with different observational objects, maybe in genetic genetic descent, there are other determinants that determine heredity genes.
Apart from that, results
Explanation:
The answer is size. The larger
the DNA molecule the slower it travels through the gel. This is because
of the restriction of their movement through the pores of the gel. The smaller DNA molecules travel furthest. The size
of the pores can be varied through by changing the mixture ratios of the agarose gel.
