What is the meaning of Prototrophic?

: having the nutritional requirements of the normal or wild type.

What is the description of strain?

A strain is a stretched or torn muscle or tendon. Tendons are tissues that connect muscle to bone. Twisting or pulling these tissues can cause a strain. Strains can happen suddenly or develop over time.

What are Auxotrophs give examples?

They include vitamins, purines and pyrimidines, nucleotides and nucleosides, amino acids, fatty acids, sterols, and polyamines. An auxotroph is a microorganism that is unable to synthesize one or more essential growth factors, and it will not grow in fermentation media lacking them. For example, the yeast S.

What does strain in science mean?

Strain, in physical sciences and engineering, number that describes relative deformation or change in shape and size of elastic, plastic, and fluid materials under applied forces. In the case of elongation, or lengthwise compression, the normal strain is equal to the change in length divided by the original length.

What are auxotrophic bacteria?

: requiring a specific growth substance beyond the minimum required for normal metabolism and reproduction by the parental or wild-type strain auxotrophic mutants of bacteria.

Can Prototrophs grow on minimal media?

Terms in this set (29) Wild-type, These bacteria can use simple ingredients to synthesize all of the compounds that they need for growth and reproduction. It can grow on minimal media. A medium that contains only the nutrients required by prototrophic bacteria.

What is an example of strain?

The definition of a strain is a bodily injury due to overexertion or an excessive demand on resources. An example of strain is a pulled muscle. An example of strain is reading a book in the dark, causing pressure on the eyes. A wrench, twist, or other physical injury resulting from excessive tension, effort, or use.

What are regulatory mutations?

Such a mutation – loss of an enhancer element – is called a regulatory mutation. It affects the spatial or temporal regulation of the gene without causing universal loss of the gene product.

What is poly Auxotrophs?

(pol’ē-awks’ō-trōf), A mutant organism that requires several nutrients that are not required by the wild-type organism.

What is normal strain in physics?

Normal strain occurs when the elongation of an object is in response to a normal stress (i.e. perpendicular to a surface), and is denoted by the Greek letter epsilon. A positive value corresponds to a tensile strain, while negative is compressive.

What is meant by a suppressor mutation?

A mutation that counteracts the effects of another mutation. A suppressor maps at a different site than the mutation it counteracts, either within the same gene or at a more distant locus.
