DNA sequence, while a substitution will affect only the one codon (set of: DNA. For example: Original sentence: THE BOY ATE THE HOT DOG AND CUT HIS LIP Substitution example: THE BOY ATO THE HOT DOG AND CUT HIS LIP Substitute a base Insertion example: a base Deletion example: base THE BOY ATE ETH EHO TDO GAN DCU THI SLI Insert THE BOY ATT HEH OTD OGA NDC UTH ISLI Delete a Just as you can change an entire sentence by inserting or deleting one letter, your DNA can be changed by inserting, deleting, or substituting one base. DNA is read 3 letters at a time. Each codon of DNA (set of 3 bases) codes for a piece of information. Use the key provided to interpret what the following DNA sequences are saying, and what happens when they are mutated. 1. Original DNA: ATT GCA TTT GGG CTC Coded information: My favorite Class is Science. Insertion mutation: ATT GCA TTT GGG CTC Insert a "T" between the 2nd and 3rd bases Mutated DNA sequence: My favorite Class Coded information with mutation: 2. Original DNA: CAC TGG GGA TTC Coded information: Buy One Pizza Please Deletion mutation: CAC TGG GGA TTC Mutated DNA sequence: Delete this "A" (the 2nd base in the sequence) BUY + Staples. EXCLUSIVE CODE: TTT class GGT alien ATT my GAT elephant GCA favorite GGG 15 TTC please TGG one Frameshift Mutations CCT pretty AGC fiction the GCT CAC buy GGA pizza CTC science TGC movie
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.
