Hi! I canât say I know what your problem is but I did read that the clumps in the sperm may be nothing harmful and are not necessarily a sign of an underlying disease. They can however, be painful sometimes and their cause might not always be found.
In addition to differences between genes, the arrangement of nucleic acids can differ between copies of the same gene. This results in different forms of individual genes. Different forms of a gene are called alleles. Organisms that reproduce sexually receive one complete copy of their genetic material from each parent.
Alternative splicing is a process that occurs during gene expression and allows for the production of multiple proteins (protein isoforms) from a single gene coding. Alternative splicing can occur due to the different ways in which an exon can be excluded from or included in the messenger RNA.
