Answer:
1) The protein is a tetramer, i.e., it has 4 subunits
2) The protein has two identical subunits with a molecular weight of 90 kDa
3) Because this protein contains two subunits with identical molecular weight (90 + 90= 180)
Explanation:
160 kDa + 90 kDa + 60 kDa = 310 kDa >>
Subunit X = 400 kDa - 310 kDa = 90 kDa >> Two subunits with a weight of 90 kDa likely linked by disulfide bonds (i.e., non-reducing conditions can break all bonds except sulfide interactions)
Answ
Left - antigen
Top Right - antibody
Bottom right - B cell
Explanation:
Antibodies (top right label) are Y shaped proteins involved in the detection of pathogens. They specifically detect molecules associated with pathogens called antigens (left).
Antibodies are produced by B cells (bottom right) which are a specialised class of immune cells that make up part of the adaptive immune system. B cells are often referred to as white blood cells.
