What is a possible function of these additional amino acids? - ️️Direct the protein to the rough endoplasmic reticulum Assist in protein folding Which biomolecule can encode the most unique sequences for a given length? - ️️protein Based on Griffith's experiments, where can you conclude the heritable material is located? - ️️Loosely attached to the cell wall/membrane Which of the following could be used as a negative control in the Avery experiments? - ️️Buffer solution only Your group is assigned to repeat Avery's experiments in BIOL 30 lab. You are given plates of R cells and tubes of the extracted S factor. In which of the following cases would you see the R cells be transformed into S cells. - ️️All of the above EXCEPT when you add S factor + DNAase Based on the results of Avery's experiments, which biomolecule most likely constitutes the heritable material? - ️️DNA In Table 1.2, which biomolecule was more likely to be found inside the cell? - ️️DNA Which DNA base pairs contain two rings? - ️️Adenine and Guanine The nitrogenous bases are held together by which kind of bonds? - ️️Hydrogen bonds What method of replication did Meselson & Stahl determine was used in DNA replications? - ️️Semi-conservative If protein is the heritable material, how many unique sequences of 10 amino acids are possible? - ️️20^10The following image is of DNA bands following 2.5 generations as well as a quantification of the density of both bands. Which of the bands contains the most DNA? - ️️A In an adult, the gene encoding the fetal hemoglobin protein is most likely to be - ️️Hypermethylated Which of the following is not necessary for protein translation? - ️️DNA/chromosomes Some amino acids are encoded by four codons. Which base of these codon can be altered without changing the encoded amino acids? - ️️Third You are studying an unknown protein and determine that the mRNA sequence for the protein is the following: AUGUUUAUUGCCUGA Using the following figure, determine how many amino acids are in this protein. - ️️4 Under what condition would you expect to see high amounts of insulin in the blood? - ️️After drinking a sugary soda After eating a big meal If DNA is the heritable material, how many unique 10 DNA base pair sequences are possible? - ️️4^10 Which segments of mRNA are spliced out: - ️️Introns What type of bond is used by the ribosome to put two amino acids together when making a protein? - ️️Covalent bond What characteristics are important in the type of RNA that serves as the template for protein translation? - ️️High turnover rate Variety of sizes Which form(s) of RNA are the most stable / long-lasting? - ️️rRNA You set up an experiment with yeast grown on lots of food (glucose) vs. very little glucose. Would you expect to see differences in the amount and make-up of tRNA between the two groups? - ️️no
