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 anoth…

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.

Students have asked these similar questions

Although it is well known that X-rays cause mutations, they are routinely used to diagnose medical problems, including potential tumors, broken bones, and dental cavities. So why do we still use X-rays in medicine anyway? What precautions need to be taken?

How is it possible that some, but not all, mutations get passed from one generation to the next?

(a) Mutations have many different causes and effects. Outline how mutations can affect the gene pool of a population. (b) Draw a table that identifies THREI types of mutagens, describes how each mutagen causes mutation and describes the effects of each mutagen.
