Solutions

Expert Solution

E​psilon and delta DNA polymerases proofread the newly formed strand and remove and replace incorrectly paired nucleotides.

During DNA replication process, the incorrectly paired bases are corrected by DNA repair process. In our body, we have three repair mechanisms namely proofreading, mismatch repair, and excision repair mechanisms.

Proofreading mechanism is performed by DNA polymerase that ensures accurate DNA replication. If it recognises any mismatched pairs, remove it and try to repair with new base pair. In eukaryotes, DNA polymerase epsilon and delta type can perform proof reading.

Base substitution mutations and frameshift mutations If a segment of DNA were replicated without any errors, the replicated strand would have the following sequence of nucleotides:5' - ACTACGTGA - 3'Sort the following replicated DNA sequences by the type of point mutation each contains (frameshift, base substitution, or neither), as compared to the correct sequence shown above. Sort the items into the appropriate name as frameshift mutation, base substitution mutation and or neither5'-ACTCGTGA-3'5'-ATTACGTGA-3'5'-ACTACGTGT-3'5'-ACTAAGTGA-3'

Write a program to remove extra blanks from text files. Your program should replace any string of two or more blanks with one single blank. It should work as follows: * Create a temporary file. * Copy from the input file to the temporary file, but do not copy extra blanks. * Copy the contents of the temporary file back into the original file. * Remove the temporary file. Your temporary file must have a different name than any existing...
