Draw a DNA helix opened up to copy a single gene (CAREFUL this is NOT a replication bubble). You can make lines straight and parallel if you would like On the bottom strand starting in middle and going to left,draw an arrow to show the beginning of transcription Add 10 DNA bases of your choice (A,T, C or G) along the bottom line to left of arrow. Add the complementary bases along the top line. Beginning at the arrow, transcribe the DNA into RNA. Write the appropriate letters. Label 5’ and 3’ ends of all nucleic acids. Label the template strand and the coding (or sense) strands of DNA. Label the promoter.
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.
