Eukaryotic DNA is typically organized into two major regions called euchromatin and heterochromatin. Which of the following applies to euchromatin? They are regions of little or no transcription activity. They are regions of highly condensed chromatin. They are regions that are uncoiled and active in transcription. They may refer to regions near the ends of chromosome (telomeres). They refer to regions that contain the centromere.

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.
