Which of the following statements about the import of protein to the nucleus is correct? Choose all that apply.
dem82 [27]

The correct statements are:

•An NLS can be a monopartite or bipartite signal which includes a significant number of basic amino acids.

• The recycling of importins back to their original conformation requires GTP hydrolysis in the cytoplasm.

The other answers are incorrect because GTP is not required for an importin to bind to an NLS but for the release of importin and an NES or nuclear export signal  is the sequence  in a protein for export from the cell nucleus to the cytoplasm, not to the nucleolus.

Differentiate Humoral immunity vs cell mediated immunity
trapecia [35]

Answer:

Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.

The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.

Cell cycle is divided into two stages: interphase (lasts 3/4 of the cycle) and phase M (1/4 of the cycle).

Interphase is also divided into three stages:

Phase G1

Protein and RNA synthesis is done.

Phase S

DNa synthesis is done.

Phase G2

Protein synthesis continues and the cell grows to start the division.
