Several changes in chromatin proteins associated with active genes have been described. One common way of controlling gene expression is by altering the intitiation rate for RNA polymerase. You are carrying out a genetic survey of a Greek village, where a number of individuals have B-thallasemia. You would like to compare the sequence of their B-globin genes to the normal sequence. Provide a brief outline of the steps in this procedure.
Ovalbumin is the major protein of egg white.
The ovalbumin gene contains 8 exons separated by seven introns. Explain your answer. Describe how eukaryotic enhancer elements differ from proximal promoter elements. Sandworms reproduce so prolifically that there soon are enough for molecular studies. Extractions of nucleic acid show that the sandworm is a DNA-based life form.
