The following is the base sequence on the coding strand of a DNA molecule. AAT GCC AGT GGT TCG CAC Rewrite the base sequence above and underneath write the base sequence for the template DNA strand. Write the base sequence for the strand of mRNA transcribed from the original strand of DNA or template strand. Remember transcribing means making mRNA from DNA. Write the amino acid sequence translated from this mRNA. Translating means making an amino acid chain from mRNA. A) If the fourth nucleotide in the coding DNA strand was changed from a G to a C, what would be the base sequence of the new strand of mRNA? b) What would the resulting amino acid fragment be? A) If a G were added to the coding DNA strand after the third nucleotide, what would be the base sequence of the resulting mRNA? B) What would the resulting amino acid fragment be?
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.
