Now, line up the first three nucleotides of the DNA strand with the first three spaces for mRNA.Write the matching nucleotide on the mRNA strand. (Remember to use Uracil).**Leave the short ones blank, that’s just to show you codons. Once you have your mRNA completed, fill out the mRNA column. You have now transcribed the strand of DNA to mRNA, which can now leave the nucleus. Remember acodon is a sequence of three nucleotides. Draw a box around all the codons (or three in a row). These areimportant for looking at how that information is translated into amino acids or Translation. Think of it asthe language of nucleotides is being translated into the language of amino acids.Quick Check Which organelle is considered the ‘work table’ for protein synthesis? These amino acids are brought to the Ribosome with the help of another type of RNA that transfersthe amino acid to the mRNA strand, also called tRNA. These molecules of tRNA also have 3nucleotides exposed that are the opposite of the codon (or anti-codon) so they can bond together.Each tRNA molecule carries the appropriate amino acid.Using the blue tRNA molecules, write out the anti-codon it would have to have to match up with yourstrand. On your chart, fill in the anti-codons in under the column tRNA. Strand : mRNA codon tRNA anti-codon AA(short) AA( full name)
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.

These amino acids are brought to the Ribosome with the help of another type of RNA that transfers
the amino acid to the mRNA strand, also called tRNA. These molecules of tRNA also have 3
