nucleus
Protein-coding genes in eukaryotes provide instructions for making proteins, which are essential for various cellular functions such as growth, repair, and regulation of biological processes.
chromosomes
According to the chromosome theory of inheritance, genes are carried from parent to their offspring on chromosomes.
homeotic genes
The main reason for this is evolution. When we say an organism is evolved, it means that they have more advanced systems - and their pathways are more complex. Even genetically speaking, evolved organisms generally have more types of genes for a particular function. Now, when you talk about cellular metabolic pathways, lower organisms like prokaryotes are only evolved enough to code for the enzymes that are a part of or regulate glycolysis. They do not contain the enzymes, as well as the structures (mitochondria) to conduct higher cellular functions like Krebs cycle or ETC. In comparison, eukaryotes have genes for the same and thus are able to carry out these functions. It all comes down to whether it has a gene to do that particular function.
Genes are carried within DNA, which is organized into structures called chromosomes. Chromosomes are located within the nucleus of a cell, and they contain the genetic information necessary for an organism's development and function.

The genes carried on the X chromosome are called X-linked genes, while the genes carried on the Y chromosome are called Y-linked genes. These genes play a role in determining various traits and characteristics in individuals.
Sex-Linked genes.
The information in DNA is carried in its sequence of nucleotides, which form genes that encode for proteins and regulate cellular functions. In RNA, the information is carried in a single-stranded molecule that is transcribed from DNA and includes messages for protein synthesis.
Yes, genes serve as a set of instructions for the synthesis of proteins, which are crucial for various functions in the body. These proteins are key players in the formation and regulation of different cellular structures and processes.
