Due to the sensitive location of splice sites, mutations in the acceptor or donor areas of splice sites can become detrimental to a human individual. In fact, many different types of diseases stem from anomalies within the splice sites. A study researching the role of splice site mutations in cancer supported that a splice site mutation was common in a set of women who were positive for breast and ovarian cancer. Thes… Several methods of RNA splicing occur in nature; the type of splicing depends on the structure of the spliced intron and the catalysts required for splicing to occur. The word intron is derived from the terms intragenic region, and intracistron, that is, a segment of DNA that is located between two exons of a gene. The term i… drag and drop math mr nussbaum
