Do all chromosomes have centromeres?

People also ask: How many centromeres is a chromosome made up?

Cliffs AP bio states that there is one centromere per chromosome. However, after a duplicate chromosome splits the chromatids can be considered chromosomes since each chromatid contains 1 centromere.

What is a centromere? How can it differ between chromosomes. The centromere, which is located in the middle of a chromosome, is responsible for sister chromatid adhesion and kinetochore production. Although the overall structure of the centromere is different for each species, it usually has a series repeating sequences and associates the histone H3 variant CENH3(CENP-A).

What happens if there's no centromere?

Centromere is an important part of the distribution of genetic material to newly formed cells. Without a centromere the cell cycle would not continue. It's possible for the cell to become irreparable if it is not treated.

Are centromeres able to reproduce?

Centromeres are a part of the DNA and chromosome. They replicate when the rest is replicated. This occurs during the S (synthesis phase); the S phase is when DNA duplication occurs.
