You have sequenced the genome of the bacteriumSalmonella typhimurium, and you are using BLAST analysis to identify similarities within the S. typhimuriumgenome to known proteins. You find a protein thatis 100 percent identical in the bacterium Escherichiacoli. When you compare nucleotide sequences of theS. typhimurium and E. coli genes, you find that their nucleotide sequences are only 87 percent identical.a. Explain this observation.b. What do these observations tell you about the meritsof nucleotide- versus protein-similarity searches inidentifying related genes?

Genetic analysis

Genetic analysis refers to the process of studying and analyzing changes in chromosomes or genes using different methods in scientific fields such as genetics and molecular biology. It involves the localization and identification of genes and the detection of inherited or genetic disorders caused by mutations or other abnormal variations in our genome.
