Review this diagram; select the response that BEST describes label #2.
Locus (genetics) - Wikipedia
a
centromere
b
sister chromosomes
c
chromatin
d
chromatid
The best label for #2 in the diagram is: d) chromatid.
To answer this question, let's first understand the given options.
a) Centromere: The centromere is a specialized region of a chromosome that holds the two sister chromatids together during cell division.
b) Sister chromosomes: This term is not commonly used in genetics. However, chromosomes typically exist in pairs, with each member of the pair called a sister chromatid.
c) Chromatin: Chromatin refers to the DNA and protein material that makes up chromosomes in their relaxed state, typically observed during interphase.
d) Chromatid: A chromatid is one half of a duplicated chromosome that is joined at the centromere to its sister chromatid.
Now, let's analyze the given diagram and its context, which is "Locus (genetics) - Wikipedia." A locus is a specific position on a chromosome where a specific gene or DNA sequence is located.
Based on this information, the term "label #2" most likely refers to one of the duplicated halves of a chromosome. Therefore, the correct answer is option d) chromatid.
To fully confirm this, you can visit the Wikipedia page mentioned in the question. There, you can find the diagram and its corresponding labels to verify the answer.
