Question | Answer |
Rod-shaped structures made of DNA and proteins | Chromosome |
Proteins that help maintain the shape of the chromosomes and aid in packing DNA, and is wrapped in DNA | Histone |
One o the two identical halves that make up a chromosome, and form as the DNA copies itself before cell division | Chromatid |
The point where two chromatids are attached | Centromere |
The less tightly packed DNA-protein complex | Chromatin |
Chromosomes that determine the sex of an organism, and that may carry genes for other characteristics | Sex Chromosome |
All of the other chromosomes in an organism that are not sex chromosomes | Autosome |
The two copies of each autosome, which are the same size and shape and carry the same genes for that trait | Homologous chromosome |
The number and visual appearance of the chromosomes in the cell nuclei of an organism or species | Karyotype |
