Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm. The centromere is located at the cell’s constriction point, which may...
In a chromosome, DNA is a double-stranded molecule (double helix). As such, it consists of two strands that wind around each other into what resembles a helical spring (like a twisted ladder). For the double-stranded molecule to be formed, each nucleotide in the DNA strand has to pair/...
Polysomy is a condition where there is more than one copy of the chromosome relative to the normal. Trisomy (2N+1) and tetrasomy (2N+2) are examples of polysomy.
