which structure present in the nucleus region of a living cell bear genes

DNA (deoxyribonucleic acid) is found in the nucleus of a living cell and bears genes. DNA is either organised into a chromatin network in non-dividing cells or in chromosomes in dividing cells.

Chromatin structure present in the nucleus region of a living cell bear genes. Chromatin marerial is the uncondensed material, which gets condensed and coiled to form chromosome, mostly during cell division.
But, properly saying, Chromosomes (fine thread-like filaments inside the nucles, which carries genetic characters from parents to offspring), contain DNA, which bears genes. The double stranded structure of DNA is very common.
DNA, however, remains in partly folded and partly opened condition inside the nucleus, since it is a large biomolecule. This position of DNA is in chromatin reticulum.
A gene, however, is the basic physical and functional unit of heredity, made up of DNA, transferred from parent to offspring, and is held to determine some characteristic of the offspring.
