Chromatids contain chromosomes.

Answer 1

The correct statement about genetic material is:

**Chromosomes are made up of genes.**

Here’s a brief explanation for the incorrect statements:

- **Genes encode deoxyribonucleic acid**: This is misleading; genes are segments of DNA (which is deoxyribonucleic acid), rather than encoding it.

- **Centromeres connect two chromosomes**: This is incorrect; centromeres are the regions that connect two sister chromatids within a single chromosome, not two separate chromosomes.

- **Chromatids contain chromosomes**: This statement is also incorrect; chromatids are copies of a chromosome that are joined together at the centromere before cell division.

So, the statement "Chromosomes are made up of genes." is the only accurate statement.
