Nonsense mutations release ribosomes within the RNA of a multigene operon, though, enabling rho to terminate transcription prematurely and prevent expression of distal genes in the transcription unit even though their open reading frames contained wild-type sequences

Nucleotide excision repair (NER) systems excise a sequence that includes the damaged base(s). a new stretch of DNA is then synthesized to replace the excised material.

binding by a ribosome, many prokaryotic ORFs contain a short sequence upstream (on the 5’ side) of the start codon called the ribosome binding site (RBS). This element is also referred to as a polypurine stretch Shine–Dalgarno sequence.

#Unit 8. Inheritance Biology

The relation between genotype and phenotype is straight forward. Each genotype produces a single phenotype, and most phenotypes are encoded by a single genotype.
