Which statement about sister chromatids is true?


Question 3 Which of the following statements about sister chromatids is TRUE? All of these statements about sister chromatids

Answer

After reading some books, I think : The correct answer is option B)Sister chromatids are exact copies of each other and are formed just prior to cell division. This statement is absolutely correct. Other options are wrong because : i)In the case of the first option, this is wrong because all options are not correct ii)In the case of the third option, this is wrong because sister chromatids are mostly identical , they carry the same allele and different versions of the gene , this is because they derive from the original chromosome iii)in the case of the fourth option, this is wrong because sister chromatids are produced during the S phase of interphase

iv)in the case of the fifth option, this is wrong because sister chromatids are attached with centromere by a protein-like structure kinetochore which is connected with spindle fiber.
