An explorer discovers a strange new species of plant and sends some of the plant tissue to a geneticists to study. The geneticist isolates chromatin from the plant and examines it with an electron microscope. She observes what appeared to be beads on a string. She then adds a small amount of nuclease, which cleaves the string into individual beads that each contain 280 base pair of DNA. After digestion with more nuclease, a 120 base pair fragment of DNA remains attached to a core of histone proteins. Analysis of the histone core reveals histones in the following proportions.    On the basis of these observations what conclusions could the geneticists make about the probable structure of the nucleosome in the chromatin of this plant?

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
