The correct statement about genetic material is:
Chromosomes are made up of genes.
This statement is accurate because genes are segments of DNA located on chromosomes, and chromosomes themselves are structures that organize and contain genetic material.
To clarify the incorrect statements:
- Genes do not encode DNA; rather, they are segments of DNA that encode proteins or functional RNA.
- Chromatids are the duplicated forms of chromosomes that are joined at the centromere; they do not contain chromosomes but are part of a chromosome during cell division.
- Centromeres connect two sister chromatids (not two chromosomes).
