Missense mutation Study guides, Revision notes & Summaries

A change occurs in one nucleotide of a triplet within a protein-coding portion of a gene. This change results in a new triplet that codes for a stop codon. What is this mutation called? Nonsense mutation A point mutation occurs in which a single nucleotide change results in a codon that codes for a different amino acid. What is this mutation called? Missense mutation A single nucleotide is changed. What is this mutation called? Point mutation A point mutation occurs in wh...

Disease and the Environment • Understand the major functions of cells and the difference between viruses, bacteria Viruses are either naked or enveloped. Enveloped can be easily disrupted with alcohols but naked are more stable. Bacteria has different states of living. Some are free to flow while others stack up and create biofilm making them resistant • Explain...

WGU Biochemistry Final Review 1. The polymerase chain reaction is a tool used to study protein structure. True False False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary stran...

BIOL 112 Final Exam Learning Goals (Starts at mutations) 100% Pass Identify the different types of point (base substitution) mutations; missense, nonsense and silent mutations. POINT MUTATION: = A change in a single nucleotide Types: 1) Silent Mutation = When the redundancy of the genetic code kicks in and the change in that single nucleotide results in the same amino acid produced as the original code. 2) Missence Mutation = When the change in a single amino acid changes the am...
