I believe that the most common antibody switch is from IgM to IgG.
Class switching occurs by a mechanism called the class switch recombination binding. It is a biological mechanism that allows the class of antibody produced by an activated B cell to change during a process known as isotype or class switching. The mechanism changes a B cell's production of antibodies from one form to another, such as from the isotype IgM to the isotype IgG.
Carbon dioxide and oxygen cannot pass through but move in and out
Answer: The options are not given, here are the options.
A) No the DNA in circulating erythrocytes ins needed to help transport O2 through the capillaries
B) No circulating erythrocytes contain DNA.
C) Yes DNA is responsible for cell division in most cells
D) Yes circulating erythrocytes carry DNA nutrients through the capillaries
The correct option is B.
No circulating erythrocytes contain DNA.
Explanation:
Erythrocytes or red blood cells is a biconcave disc that contain haemoglobin which help to carry oxygenated blood in the body.
Circulating erythrocytes do not contain dna because they lack nuclei and organelles, cannot synthesize any RNA, therefore cannot divide and have limited repair capabilities.
Because they cannot carryout protein synthesis, no virus can evolve and invade the red blood cells.
The endoplasmic reticulum, or ER, and Golgi apparatus, prepare molecules, including proteins, hormones and lipids, and package them in vesicles for transport. Rough ER is studded with ribosomes that synthesize proteins, while the smooth ER manufactures lipids.
