Multiple Choice
In the context of eukaryotic chromosome structure, which term best describes a thread-like structure of DNA that carries genes?
A
Nucleosome
B
Ribosome
C
Chromosome
D
Centromere
Verified step by step guidance1
Understand the key components involved in eukaryotic chromosome structure: DNA, proteins, and the organization of genetic material.
Recall that a nucleosome is a unit of DNA wrapped around histone proteins, forming the basic repeating unit of chromatin, but it is not the entire thread-like structure.
Recognize that a ribosome is a cellular structure involved in protein synthesis and is not related to DNA or chromosomes.
Identify that a centromere is a specific region on a chromosome important for chromosome movement during cell division, but it is not the whole DNA thread.
Conclude that the term 'chromosome' best describes the entire thread-like structure of DNA that carries genes in eukaryotic cells.
