Which of the following are true of sister chromatid?
Answer Expert Verified. C is the correct answer. Sister chromatids are separated from each other during the mitosis phase of reproduction. A is incorrect – sister chromatids differ from homologous chromosomes, which are different copies of one chromosome, each inherited from a parent.
What is the function of chromatids?
Function of Chromatids
It authorizes cells to store two copies of their information in preparation for cell division. This is important to make sure that daughter cells are healthy and fully functional, carrying a full complement of the parent cells DNA.
What are the characteristics of chromatids?
A chromatid is a replicated chromosome having two daughter strands joined by a single centromere (the two strands separate during cell division to become individual chromosomes).
What are the two parts of cell division?
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.
Can a chromosome have one chromatid?
When fully condensed, replicated chromosomes appear as thick X-shaped structures that are readily observed under the microscope (see figure below). Chromosomes can have 1 or 2 chromatids, depending on whether they have replicated.
What is the difference between DNA and chromatin?
The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes.
|Difference between Chromosomes and Chromatin|
|Composed of nucleosomes||They are condensed chromatin fibers|
What are two chromatids together called?
…of two identical replicas, called chromatids, joined at a point called the centromere. During mitosis the sister chromatids separate, one going to each daughter cell.
