What are restriction enzymes? A. Carriers of foreign DNA into a cell that "restrict" the type of DNA introduced into the cell in

the recombinant DNA technique. B. Protective enzymes found in some bacteria that "restrict" the type of DNA allowed in the bacterial cell by catalyzing the cleaving of other types of DNA. C. DNA of an organism that contains genetic material that comes from another organism and "restricts" the enzymatic activity of the host. D. Circular, double-stranded DNA found in the cytoplasm of bacterial cells that "restrict" the amount of DNA in the bacteria.

Answer:

B; Protective enzymes found in some bacteria that "restrict" the type of DNA allowed in the bacterial cell by catalyzing the cleaving of other types of DNA.

Explanation:

A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.

Differentiate between the lithosphere and asthenosphere
allsm [11]

Answer:

Lithosphere made the earth outermost layer, crust and upper portion of mantle.

Asthenosphere made the middle layer of earth.

Explanation:

Lithosphere:

Lithosphere made the earth outermost layer, crust and upper portion of mantle.

It is made up of tectonic plates.

Lithosphere present over the asthenosphere.

Lithosphere have low temperature as compared to asthenosphere.

Its rocks are rigid.

It is less viscous and dense

Asthenosphere:

Asthenosphere made the middle layer of earth.

When material present in asthenosphere solidify it becomes the part of lithosphere.

Asthenosphere have high temperature as compared to the lithosphere.

Its rocks are plastic and have tendency to flow.

It is more viscous and dense.

Anthocyanin is a pigment that gives flowers and leaves purple colors. The M gene codes for a transcription factor (Myb) that pro
eduard

Answer:

Anthocyanin is not produced in the plant cells

Explanation:

Anthocyanin is not produced in plant cells with the genotype mm.

As you can see from the question above, anthocyanin is responsible for the purple color of the flowers. Anthocyanin is encoded by the M gene, which is a dominant gene. Because it is a dominant gene, we know that it will be expressed in plants with the Mm and MM genotype, but will not be encoded by plants with the mm genotype. With this we can conclude that plants that have the mm genotype do not have purple color, because anthocyanin is not produced in the plant cells of these plants, since they do not have the M gene.
