8. Write composition of chromosomes. |
|
Answer» Each chromosome has a CONSTRICTION point called the centromere, which divides the chromosome into two SECTIONS, or “arms.” The short arm of the chromosome is labeled the “p arm.” The LONG arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes. DNA and HISTONE proteins are packaged into structures called chromosomes. |
