So, if you have lung tissue then the only simpler organization is cells. These are simpler because cells are what make up tissue, just as tissue makes up organs. Through the levels, the more simple something is then the smaller it is, relatively.
Answer:
Actually, they have all of these features
Explanation:
Sister chromatids are replicated chromosomes formed during DNA replication at the Interphase stage. Since one is a replica of the other, they are the same in lenght, alleles content and every other aspect. They are joined together at the centromere.
Sister chromatids are separated from each other into each daughter cell at the Anaphase II of meiosis II and Anaphase of mitosis specifically. Hence, they remain attached to one another by their centromere until they reach Anaphase. Every chromosome contains the telomere at their end region and it plays a vital role in ensuring that neighboring chromosomes do not join.
Ur answer would be evolution
