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.
Explain how sequences within the RNA determine where splicing occurs.
Transcription is a process that converts DNA into mRNA in the nucleus.
*Mature mRNA will be transported to the cytoplasm for translation into protein.
*The mRNA transcript will contain noncoding regions which do not code for proteins called introns and they have to removed before mature mRNA transported to the cytoplasm.
* DNA stretch that code for amino acids in called exons. During splicing, introns will be removed from pre mRNA by spliceosome and exons will be spliced back.
* If introns are not removed, then RNA codes for nonfunctional protein.
