Which of the following mutations would most likely be identified as a chromosomal translocation?

A sequence of bases encodes for genes XXY. A portion of another chromosome breaks off and inserts within genes XYZ.

A mutation occurs while copying a chromosome. Instead of reading EFGHI, the chromosome reads EFGFGHI.

The genetic sequence is MNOPQ. A mutation occurs and the sequence of bases that encodes for gene N is not copied.

The sequence of bases on the mRNA reads CUU and codes for the amino acid Leucine. A mutation occurs and the mRNA sequence changes to CCU and now codes for the amino acid Proline.

Which is an advantage of having memory cells when a pathogen is encountered for a second time. a) the memory cells are what proliferate into clones of cells in response to the binding of an antigen. b) memory cells are vital to the primary immune response in that they immediately recognize pathogens even at the first encounter. c) memory cells are essentially effector cells that are short lived and attack antigens even without having a receptor specific to that antigen. d) it ensures that more lymphocytes with a receptor specific to a particular antigen will be present than in a host that had never encountered that pathogen.
