17. Complete the following Central Dogma Grid Puzzles: First determine which DNA strand is the template (look at provided nucleotides). Label template and coding/sense (non-template) strand in first column. In the second column, label the 5' and 3' ends of DNA and RNA sequences and the amino (N) and carboxyl (C) ends of the polypeptide. The last four columns represent transcriptional and translational alignments (reading frame). This is from within a coding region so you don't have to find a start codon. Fill in all nucleotides and amino acids using the mRNA code table on the last page. a. On this first grid, assume that the DNA and RNA templates are read left to right.

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.
