Regarding the process of gene transcription in eukaryotes, it is correct to state that A)The transcription process is terminated when the RNA polymerase complex reaches the final region of the gene with the poly-adenylation signal. B)The RNA polymerase II transcription elongation complex contains transcription factors such as the TATA box binding protein C)The opening of the region of DNA that will be transcribed is done by the DNA helicase, present in the transcription complex.

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.
