What is the result of Frameshift mutations from the insertion or deletion of nucleotides within the coding sequence?

What is a disorder caused by errors in transcription? What kind of error is involved?

One of the most confusing aspects of determining the protein sequence that will be derived from a gene is keeping track of the polarity or directionality of each nucleotide sequence strand. Which DNA strand is identical to the mRNA transcript? Which DNA strand codes the RNA transcript?

Define and compare the outcomes of the following types of nucleotide substitutions, insertion or deletions. Which is likely to cause the least dramatic mutant effect? a) missense mutations b) nonsense mutations c) frameshift mutations d) silent mutation
