I believe using gel electrophoresis to separate and identify plasmids and short linear pieces of DNA would be important if one is making a recombinant plasmid and has to verify that he/she has been successful. Gel electrophoresis is a technique that is used to separate mixtures of DNA, RNA, or proteins according to molecular size. The molecules being separated are pushed by an electrical field through a gel that contains small pores.

Histologically, what feature is shared by all tonsils but is absent in other malt nodules?
ira [324]

Crypts Feature is shared by all tonsils but is absent in other malt nodules. Anatomical structures called crypts are deep, narrow incisions into larger structures. The Crypts of Lieberkühn are a typical type of anatomical crypt.

It is not the only form of the tonsil, though; some tonsils also feature crypts. The deep regions of these tonsils are accessible to the outside world through these crypts, making them more susceptible to infection. An intestinal gland, also known as a Lieberkühn crypt or intestinal crypt, is a gland that can be found in the small and large intestines' intestinal epithelium between villi (or colon).

The epithelium that covers the glans and intestinal villi are made up of a variety of cells, including enterocytes (which absorb water and electrolytes), goblet cells (which secrete mucus), enteroendocrine cells (which secrete hormones), cup cells, tuft cells, and Paneth cells (which secrete antimicrobial peptides) and stem cells at the base of the gland.

In some species of Drosophila, there are genes on the Y chromosome that are not on the X chromosome. Imagine that a new allele a
mr_godi [17]

Answer:

True

Explanation:

The Drosophila like the mammals possess X and Y chromosomes but as in males in which the XX is female and XY is male, the sex In Drosophila is not determined by the presence of Y chromosomes as a male determining factor are present on the autosomes.

However, the Y chromosome is important for males as they are involved in the formation of the sperms therefore the presence of Y is important. In the given question if the allele is present ion the Y chromosome which can reduce the size therefore the allele is passed on to the males only ans no females.

Thus, true is the correct answer.

the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males. In flies, the Y chromosome is not involved in determining sex. Rather, it contains genes active in forming sperm in adults.
