Silent mutation will cause no change in amino acid sequence of the protein polypeptide chain hence no change in function of protein. Base pair change will still from the same amino acid.

Explanation:

When a single base of DNA or nucleotide gets change with no affect on the amino acid formed it is termed silent mutation.

In silent mutation, if a nucleotide gets change due to mutation the amino acid formed in translation would be same. This happens because substitution of base or new base codes for the same amino acid.

example in codon AAA if 3rd A gets change to G due to mutation and become AUG. Both these codons code for lysine.

Thus when amino acid is not changed the polypeptide will not change hence no confirmational or functional change in the protein.

olga2289 [7]

Answer:

A. stratified squamous epithelium; absorption

Explanation:

Stratified squamous epithelium are composed of multiple layers of cells which rest on a basement membrane. Superficial layers are made of squamous cells and underlying layers can also be made of cuboidal or columnar cells.

Stratified squamous epithelium  is generally present in area where there is frequent physical or chemical abrasion. It protects the underlying structures from the stress. Hence, it is found wherever the body comes in contact with the outer environment like skin, digestive system and respiratory system. It also prevents water loss and desiccation.

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.
