In Hedrick and Davis’s three stage process aimed at identifying the TCR gene, the third stage identified two genes for the TCR. This final identification process distinguished these messages from the genes which could have included genes for_______.1 pointantibodiesikarosMHC IIpre-a chainubiquitin

In this diagram of a rearranged TCR chain gene, the pointer indicates a constant region. This drawing oversimplifies the structure of this part of the gene in that it does NOT show _____.1 pointthe one-turn RSS at the upstream (5’) endthe two-turn RSS at the upstream (5’) endthe one-turn receptor at the downstream (3’) endthe two-turn receptor at the downstream (3’) endthe four exons and three introns in the region

Whatis the function of the 5’ leader sequence of the heavy chain gene?

Identifying the TCR gene was like finding a needle in a haystack and Hedrick and Davis designed three-stage process to accomplish this. If I literally had to find a needle in a haystack, first I would burn the haystack down and sieve the ashes for non-combustible objects. Then I would use a magnet retrieve iron or steel objects from the rest of the other metal, stone or ceramics. Finally, I would hand-pick my way through the objects clinging to the magnet. In this analogy, the discarded ash from the burned hay represents ________ and the magnet represents the _____.1 pointRER messages; subtraction hybridization protocolRER messages; use of different T-cell lineages to bind T-cell sequencescytosolic messages; subtraction hybridization protocolcytosolic messages; use of different T-cell lineages to bind T-cell sequencesB-cell messages; subtraction hybridization protocolB-cell messages; use of different T-cell lineages to bind T-cell sequences

The T cell receptor (TCR):Select one alternative:Has enormous binding diversity created by gene segment rearrangement.Consists of 2 protein chains, each with variable and constant domains.Contains only one antigen-binding site.All of the above

There is no gene for ______ located in the MHC locus.1 pointcytokinesproteins that form part of the MHC I presenting moleculeenzymes that transport peptides into the ERproteins that determine the length of peptides hydrolyzed in the proteasomeproteins that associate with CD4
