This article applies chromosomes holokinetycznych ( holocentrycznych ) plants. Chromosomes are kinetochore diffusion Holokinetic extending the entire length of chromatids . With this structure, the kinetochore Holokinetic chromosomes may be fused (full or partial symploidalność ) or fragmentation (partial or complete agmatoploidalność ) without negative effects on mitosis .

According to the generally accepted principles , it is believed that the gene and its protein product may be involved in tumorigenesis , tumor tissue if is detectable chromosomal abnormalities and / or mutation of this gene , and the expression and function of the gene encoded proteins are significantly disorder . It appears that the receptors triiodothyronine (TR) is one of these proteins. This hypothesis is supported by four facts .
