Question

2. (12 pts) We discussed in class that the la strand in DNA replication contains okazaki fragments. If these fragments are about 1500 nucleotides long and you had an E. coli genome of7.5 x 10 base pairs, how many fragments would be required to replicate this organism's genome? 3. (16 pts Draw the general structure of a tRNA. Label the names of the arms, the acceptor stem, the anticodon, and where base pairs occur. Also draw an amino acid of your choice onto the tRNA in the appropriate place. Label the amino and its codon (keep in mind the genetic code is redundant Label what the sequence of the anticodon will be for that amino acid.

Explanation / Answer

50,000 okazaki fragments would be required for replicating the genome of 7.5 X10^6 base pairs in the lagging strand synthesis. Leading strand synthesis is the continues process where as lagging strand synthesis is the discontinues process forming okazaki fragments.
