The answer is chromosomes because the chromosomes, and the proteins made in the ribosomes are how genes are expressed in an organism. Hope I helped! =)
Gene directs the synthesis of a cellular component through what is called gene expression.
During gene expression, information from the DNA is used to synthesis proteins, through the process of transcription followed by translation.
Transcription is the process that involves use of information carried by DNA to generate messenger RNA, in the nucleus of a cell. Then translation which uses the information carried by the mRNA to generate proteins in the organelles known as ribosomes.
