Genomics

Genes are responsible for transmitting the characters located on the chromosomes from one individual to another across the generations. Genetics is the study of different genes that are involved in different functions. Genetics is a branch of biology that studies genes, genetic diversity, and heredity in living organisms. The genetic system consists of genetic notations, which is a system of signs and symbols. Genotype refers to the organism's genetic composition, and phenotype refers to the observable property of the organism.

5) The peptidyltransferase reaction begins with the hydrolysis or breaking of the bond between the carboxyl group of the last amino acid added to the growing polypeptide and the 3' end of the tRNA in the P site. How does the ribosome get the necessary activation energy to catalyze that hydrolysis reaction?
1. The enzyme activity that forms peptide bonds on the ribosome is called peptidyl transferase. Explain which molecule catalyzes this reaction?

Figure 15.16 Many antibiotics inhibit bacterial protein synthesis. For example, tetracycline blocks the A site on the bacterial ribosome, and chloramphenicol blocks peptidyl transfer. What specific effect would you expect each of these antibiotics to have on protein synthesis? Tetracycline would directly affect: tRNA binding to the ribosome ribosome assembly growth of the protein chain Chloramphenicol would directly affect tRNA binding to the ribosome ribosome assembly growth of the protein chain

1. Paramecium caudatum is a unicellular organism that can phagocytose and digest a bacterium using hydrolytic enzymes. Proteases are one example of hydrolytic enzymes that can break down proteins into polypeptides and amino acids. Name all of the organelles involved, in the order that the protease will go through, from its synthesis to its final destination. Note that this protease needs to be modified through the addition of a carbohydrate in order to be functional.
