A chromosome that has two centromeres.
To estimate radiation dose, the dicentric chromosome assay (DCA) is commonly used. This test involves analyzing blood samples for the presence of dicentric chromosomes, which are indicative of exposure to ionizing radiation. The number of dicentric chromosomes can provide an estimate of the radiation dose received by an individual. Other tests, like the gamma-H2AX assay, may also be utilized for similar purposes.

The dicentric chromosome assay is a blood test that can accurately estimate radiation dose. This test looks for changes in the structure of specific chromosomes that can occur after exposure to ionizing radiation, and the frequency of these changes can be used to estimate the amount of radiation received.
Dicentric molecular orbitals have two centers of electron density, typically involving two nuclei, while polycentric molecular orbitals involve multiple centers of electron density associated with three or more nuclei. In dicentric orbitals, the electron distribution is primarily influenced by two atoms, whereas in polycentric orbitals, the electron cloud is influenced by multiple atoms, leading to more complex bonding scenarios. This distinction affects the shapes, energies, and bonding characteristics of the resulting molecular orbitals.
Chromosomes
homologous chromosomes and autosomal chromosomes
A lobster has 100 chromosomes. Humans have 46 chromosomes, the same as a lizard. A dog has 78 chromosomes, and a fly has 12 chromosomes.
No, sex chromosomes are not referred to as homozygous chromosomes. Homozygous chromosomes have identical alleles at a specific gene locus, while sex chromosomes determine an individual's biological sex. In humans, sex chromosomes include X and Y chromosomes.

chromosomes are in cells
We have 46 chromosomes in our body. In each cell, there's 23 pairs of chromosomes.
There are about 20 living species of penguins. It depends on the kind of penguin. Most penguins have 30 chromosomes.
