Both heavy chain genes and κ light chain genes______.1 pointare found near each other on the same chromosomebegin rearrangement by joining a V to a J regionwill have the extra J regions copied into the primary transcriptwill have the extra upstream VL regions copied into the primary transcripthave two membrane-spanning exons at the 3’ end of each of the constant regions

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

After gene rearrangement, the gene pictured above can be transcribed into a message with _____ D segment(s). The diagram show three upstream V-L regions, with spacers between each one and between the V and the L. Then there is a D region separated from two J regions and a constant region. This sequence is then repeated.1 pointno chance of havingonly one0 or 1 only1 or 2 only0, 1, or 2

In this drawing of a primary transcript from a T-cell Receptor gene, the exon labeled ______ will code for the part of the protein in contact with the cytosol, the exon labeled _____ will be removed during splicing and the exon labeled ______ will wind up in the lumen of the ER. The primary transcript shows, from the left, a black rectangle (L), an intron, a pink rectangle(V), a yellow rectangle(J), and intron, another yellow rectangle, a large blue rectangle (C), a smaller blue rectangle (XC), a brown rectangle (TM) and a small blue rectangle (CA).1 pointCA; J; VCA; L; CTM; J; CTM; L; VXC; J; VXC; L; C

Each gene has a specific place on the chromosome.

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
