Yes, this is possible - although it is relatively rare. A cat in heat releases her eggs about 24 hours after mating. Theoretically all sperms that have entered her the past day can fertilize each egg. If she mated with more than one cat within these 24 hours, there can be more than one different fathers.
Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes.nder the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer.
Best Answer: A chromosome is an organized structure of DNA and protein (Chromatin) that is found in cells. Chromosomes contain DNA-bound proteins, which serve to package the DNA and control its functions. The essential unit of DNA packaging is the nucleosome. A nucleosome consists of a small amount of DNA wrapped up with protein. The proteins that interact with DNA to form chromatin comprise a family of basic proteins called histones. There are five different types of histone protein: H1, H2A, H2B, H3, and H4. Of these, two molecules each of H2A, H2B, H3, and H4 combine to form a histone octamer. DNA wraps around the octamer, making 1 3/4 turns around the protein complex. The octamer plus the DNA comprise what is called the nucleosome core. A small stretch of DNA runs between adjacent nucleosome cores, and is known as the linker. A single nucleosome consists of one core plus a linker.
