What is the relationship among cells, chromosomes, genes, and dna?

dna is a double-helix structure found in the cell nucleus. chromosomes straighten out the dna so the code can be read by genes.

dna is straightened by genes which are contained in the chromosomes of a cell.

chromosomes are tightly wound strands of dna located in cells. genes are sections of dna.

tightly wound strands of chromosomes contain genes and are found in cells. the genes are coded sequences of nucleotides read by dna.

Chromosomes are tightly wound strands of DNA located in cells. genes are sections of DNA.

Explanation:

Chromosomes and located in cells and it is true that genes are part of DNA. heredity and nucleotides.

Hope it helps you on STAAR ;)
