MAKE CONNECTIONS Speculate about whether thesame enzyme could methylate both a histone and a DNAbase. (See Concept 5.4.)
MAKE CONNECTIONS The restriction site for an enzymecalled PvuI is the following sequence:5’-CGATCG-3’3’-GCTAGC-5’
WHAT IF? DRAW IT The template strand of a geneincludes this sequence:3¿-TACTTGTCCGATATC-5¿. It is mutated to3¿-TACTTGTCCAATATC-5¿. For both wild-type and mutantsequences, draw the double-stranded DNA, the resultingmRNA, and the amino acid sequence each encodes. Whatis the effect of the mutation on the amino acid sequence?

- Q1. Predict the effects (on translation of coat gene and replicase gene) of the following mutations on phage R17 coat gene and replicase gene translation and explain the logic of your answers: a. An amber mutation (premature stop codon) six codons downstream of the coat gene initiation codon. b. Mutations in the stem loop around the coat gene initiation codon that weakens the base-pairing in the stem loop. c. Mutations in the interior of the replicase gene that cause it to base-pair with the coat gene initiation codon.arrow_forwardWHAT IF?

- WHAT IF? Suppose X-rays caused a sequence changein the TATA box of a particular gene’s promoter. Howwould that affect transcription of the gene? (SeeFigure 17.9.)arrow_forwardQ5. In lab 6, you will set up a PCR reaction to yield amplified DNA products of the rpo B(RNA polymerase B) and 16s rRNA genes. In lab 7, you will set up a sequencing reaction using about 40 ng of these PCR products that you will then add a sequencing primer to the sequencing reaction. If a sequencing reaction is set up with a 100-fold excess of primer to the PCR-amplified DNA product you want to sequence, calculate the number of sequencing primers you will need to add to this sequencing reaction. To perform this calculation, assume your 40 ng sample of double stranded DNA is 4,000 base-pairs (bp) long. Using these two variables of your PCR product [length (in bp) and amount (in g, grams)], you can calculate the number of DNA molecules being sequenced with two conversion factors using the formula below: The average weight of 1 bp is approximately ~650 (g/mole)/bp Avogadro’s number which is 6.02 X 1023 molecules/mole The easiest way to solve this problem is to figure out how much one…arrow_forwardWHAT IF?
