The figure below is a portion of a Northern blot which shows the change in abundance of the HS-X mRNA following heat show in Chlamydomonas. The time in hours is shown above. Not included in the Northern blot below is the use of a house keeping gene which is always expressed. This type of expression is described as _______________ while the expression of HS-X could be described as __________________. A. Induced, Constitutive B. Constitutive, Repressed C. Induced, Repressed D. Constitutive, Induced
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.
