Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made up of protein and a single molecule of deoxyribonucleic acid (DNA).
The unique structure of chromosomes keeps DNA tightly wrapped around spool- like proteins, called histones. Without this kind of packaging, DNA molecules would be too long to fit inside the cells.
DNA molecules in a single human cell if unwound from their histones and placed end to end, they would measure 6 feet in length.
Chromosomes play a key part in ensuring that DNA is accurately copied and distributed to new daughter cells as the parent cell divides to form new cells.
This is an example of animals adapting to their environment. The sheep got sturdier hooves to stay balanced on the rocky island and they got darker wool to match the dark rocks for hiding when in danger.
