- What Art the Features of the Series of -omes? Define the following terms: a. Genome b. Transcriptome c. Proteome d. Metabolome e. FluxomeYou 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?You don't need the internet to exchange "gene-mail" with your friends, you have your own way to share the latest genes for things like antibiotic resistance. a. What is the structure being described? b. What is the chemical composition of this structure? c. What is the function of the structure, and how does it benefit the bacteria? I'm not getting this riddle.
- The major grove of dsDNA A. Is bigger in A-DNA than B-DNA B.Is where 2 Hydroxyl groups are most exposed C. Is an artifact of crystallography D. Provides a unique binding surface determined by stretches of contiguous bases E. Is only seen in C/G rich synthetic dsDNAImagine that there is an E. coli outbreak in your area, and you would like to test the kangkong from your local grocery store. How could you modify this protocol to extract DNA from the kangkong (to identify the species) and check for presence or absence of E. coli.? Keep in mind that (i) E. coli is free-living and not an endosymbiont, and (ii) plant cells are encased in both a cell membrane and cell wall.1. Below is the base sequence of protein for normal hemoglobin and the base sequence for the sickle cell hemoglobin:Normal: GGG CTT CTT TTTSickle: GGG CAT CTT TTTa. Transcribe and translate the normal and sickle cell DNA. b. Identify this as a point or frameshift mutation. Explain. c. If the base sequence read GGG CTT CTT AAA instead, would this result in sickle cell hemoglobin? Explain.

- Define the following terms:a. wobble hypothesisb. cognate tRNAc. AUG sequenced. Shine-Dalgarno sequencee. aminoacyl-tRNA synthetaseWhich one of the following statements about BamHI is incorrect? a. it can be used to digest DNA at very specific and predictable locations. b. Its natural role is for degradation of foreign DNA molecules c. The sequence recognized by BamHI is palindromic d. BamHI generates short overhangs of single stranded DNA e. It is isolated from the bacterial species E. coliResearchers are designing several experiments to test the ability of Salmonella bacteria to develop antibiotic resistance. A culture of Salmonella bacteria is exposed to the same concentrations (200 mg/L) of an antibiotic for four days. The table shows the number of isolated resistant bacteria over a four-day period. Which of the following statements best explains these results? A - The bacteria were not affected by the antibiotic. B - After being exposed to the antibiotic, the bacteria altered their DNA. C - A new species of bacteria emerged after the antibiotics were introduced. D - Random mutations led some bacteria to be resistant and, over time, they increased in the population.
