Theyreceived these names because CD8 _____.1 point occurson TC cells and CD4 on TH hastwo peptides and CD4 has one peptide with four Ig domains isfound on twice as many T cells as CD4 wasdiscovered after CD4, 5, 6 and 7 ispresent in twice the concentration as is CD4

Question 5Considerthe co-receptors CD4 and CD8. Theyreceived these names because CD8 _____.1 point occurson TC cells and CD4 on TH hastwo peptides and CD4 has one peptide with four Ig domains isfound on twice as many T cells as CD4 wasdiscovered after CD4, 5, 6 and 7 ispresent in twice the concentration as is CD4
Solution
The co-receptors CD4 and CD8 received these names not because of any of the options provided. The names CD4 and CD8 are not related to the number of peptides they have, the number of T cells they are found on, the order of their discovery, or their concentration.
CD stands for "cluster of differentiation," which is a protocol used for the identification and investigation of cell surface molecules present on leukocytes. CD4 and CD8 were simply the fourth and eighth, respectively, to be discovered and characterized.
So, none of the options provided in the question are correct.
