Answer: Option C) The arrangement of atoms allows precise hydrogen bonding.
Explanation:
The individual hydrogen bonds between the base pairs confer stability to double helix of DNA.
The bases atoms take SPECIFIC POSITIONS or better still ARRANGEMENT, with Guanine pairing with Cytosine base atoms by three hydrogen bonds, while Adenine pair Thymine base atoms by two hydrogen bonds.
So, the arrangement of base atoms allows precise hydrogen bonding and hence STABILITY of DNA double helix.
Answer;
-Antigen presenting cells
Explanation;
-Helper T cell and inflammatory T cell TCRs recognise epitopes displayed by MHC class II molecules on the surface of antigen-presenting immune cells, including: macrophages that engulf foreign particles such as bacteria; dendritic cells that present antigen to T cells; and B cells that produce antibodies.
-Antigen-present cells APCs engluf antigens, present fragments of antigens to be recognized by T cells
. Major types; dendritic cells in connective tissues and epidermis, macrophages in connective tissues and lymphoid organs &B cells.
