Rama09 [41]3 years ago
4 0

Answer:

B.carries and allows expression of a foreign gene of interest.

Explanation:

Plasmids are the low molecular weight extrachromosomal DNA molecules that are able to replicate themselves independent of chromosomal DNA due to the presence of "ori" (origin of replication).

Plasmids serve as vectors in recombinant DNA technology as some of their genes can be replaced with the gene of interest to create recombinant plasmids.

The restriction enzymes that create the sticky ends and DNA ligases facilitate the insertion of the foreign gene into the plasmids.

The host cells are made competent to take up the recombinant plasmids. Once inside the host cell, the recombinant plasmids replicate themselves and express the gene of interest that they carry.

Which type of epithelium lines the inferior portions of the pharynx?
konstantin123 [22]

Answer:

The type of epithelium that lines the inferior portions of the pharynx is stratified squamous epithelium.

Explanation:

The pharynx is a structure made up of muscles and mucous membranes -like many internal organs- that is part of the respiratory system and is an intermediate step in the digestive tract.

This structure has two portions:

  • <em>Upper or nasopharynx </em>
  • <em>Lower, or oropharynx, in contact with the airways. </em>

Some even propose that the borderline surface between the pharynx and larynx can be called the laryngopharynx, due to its tissue structure.

The lower portion of the pharynx is covered by a squamous stratified epithelium, the inner layers of which rest on a basal lamina. The more superficial layers provide protection to the interior of the pharynx against friction, in addition to remaining lubricated by mucous secretion at that level.

The traits for blood type and Rh are the result of the presence or absence of particular on the erythrocytes.g
just olya [345]

Answer: Antigens

Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).

Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.
