What are recombinant chromosomes? How do they differ from the original parental chromosomes from which they are derived?
A recombinant chromosome is one that has been derived from a crossover andcontains a combination of alleles that is different from the parental chromosomes. Arecombinant chromosome is a hybrid of the parental chromosomes.
Briefly describe three ways that antibody diversity is produced.
First, gene rearrangement of V, D, and J domains occurs within the light- and heavy-chain genes. Second, within a given B cell, different combinations of light and heavy chains are possible. And third, imprecise fusion may occur between the V, D, and J domains.
Do you consider TEs to be mutagens? Explain.
- Transposable elements are mutagens, because they alter (disrupt) the sequences of
- chromosomes and genes within chromosomes. They do this by inserting themselves into genes.
