WebBoveri and Sutton's chromosome theory of inheritance states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance. Thomas Hunt Morgan, who studied fruit flies, provided the first strong confirmation of the chromosome theory. WebDNA is coiled around proteins called histones, which provide the structural support.

Web15 hours ago · The researchers found that EBNA1 also binds a cluster of EBV-like sequences at a fragile site on human chromosome 11 where increasing abundance of the protein triggers chromosomal breakage. Other prior research has shown that EBNA1 inhibits p53, a gene that plays a key role in controlling cell division and cell death.
