Question

Which best describes a centromere? sister chromosomes that are held together by a chromatid paired chromosomes that have genes arranged in the same order the part of a chromosome that joins the sister chromatids the material that makes up a chromosome

Answer 1

Answer:

Explanation:During cell division, the identical copies (called a "sister chromatid pair") are joined at the region called the centromere (2). Once the paired sister chromatids have separated from one another (in the anaphase of mitosis) each is known as a daughter chromosome.

Answer 2

The part of a chromosome that joins the sister chromatids

Explanation:

• The eukaryotic genetic material is linear structures of the present in the form of chromatids (thread of DNA molecule:
• These chromatids during the stages of cell division form a structure which can be passed on to the daughter cell called chromosomes.
• The chromosomes are formed by the joining of the chromatids at one part of the chromatids known as "centromere" providing X shape to the Chromosome.
• The centromere also contains a protein complex attached to the centromere called the kinetochore.
• The kinetochore allows the binding of the Mitotic spindles which helps in the separation of the chromosomes.
