Indicate Whether Each of the Following Cell-Surface Proteins Is Expressed

question 41

Short Answer

Indicate whether each of the following cell-surface proteins is expressed mainly by B cells (B), dendritic cells (D), or T cells (T). Your answer would be a four-letter string composed of letters B, D, and T only, e.g. DBBB.
( ) Co-stimulatory protein B7, which is recognized by CD28
( ) Invariant CD3 complex
( ) Inhibitory CTLA4 protein
( ) CD40 receptor, which recognizes the co-stimulatory protein CD40 ligand on a helper T cell

Definitions:

Sample Mean

The mean of a dataset, found by adding up all the values and then dividing the total by the count of values in the set.

Standard Deviation

A measure of the amount of variation or dispersion in a set of values, showing how much the values differ from the mean.

Margin Of Error

An expression of the maximum expected difference between the true population parameter and a sample estimate of that parameter.

T-Distribution

A probability distribution that arises in the sampling distribution of the sample mean, especially when the sample size is small and the population variance is unknown.
