Types of DNA Variation - single nucleotide variant (SNV) - small nucleotide insertion/deletion - dynamic mutations - microsatellite - copy number variation (CNV) Single Nucleotide Variants (SNVs) - most common type of sequence variation - >3 000 000 per person - can be benign or disease causing Initiation Codon (Start Codon) AUG (methionine) Stop Codons UGA, UAA, UAG

BIO1A03 - TEST 2 QUESTIONS AND ANSWERS RATED A what components are required for translation initiation/elongation/release factors mRNA aminoacyl tRNA synthases tRNA ribosome (ribosomal RNA + ribosomal subunit) what is the role of tRNA - transfer amino acids from the cytoplasm to a growing polypeptide strand in a ribosome - each tRNA molecule has a different shape and therefore translates a specific mRNA codon into a specific amino acid what is the structure of tRNA - made up of a single RNA st...

Bio 2024 final Mutation A change in DNA Point mutation Single base change on a chromosome Silent mutation Mutation not altering amino acid sequence Missense mutation Mutation changing a single amino acid Nonsense mutation Mutation changing a regular codon to a stop codon Frameshift mutation Addition or deletion causing sequence shift Insertion Adding a base in a sequence Deletion Removing a base from a sequence DNA to Phenotype stages DNA --> ...

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...

Transcription - synthesis of RNA from DNA Transcription results in - mRNA RNA polymerase makes -mRNA mRNA - makes proteins RNA polymerase - binds to DNA Transcription factors (TFs) - A regulatory protein that binds to DNA and affects transcription of specific genes. Can wither activate or repress expression of genes Termination of transcription - RNA polymerase reaches a terminator sequence (Stop codon) and detaches from the template Translation - Process by which mRNA is decoded and a ...

BIO 1A03 McMaster University Test 2 Review Graded A+ Translation Cellular components are able to read the genetic message in mRNA and translate the message into specific primary amino acid sequence of a protein How does tRNA structure allow for SPECIFICTY in translation? 1. Plays critical role in ENABLING the translation of the information 2. Each type of tRNA molecule is not identical and can translate a specific codon into a specific amino acid What is the structure of tRNA? - single RNA str...

Compared with cellular genomes, viral genomes: A. are larger, with more base pairs. B. are smaller, with fewer base pairs. C. have genomes composed of RNA only. D. also must have double-stranded DNA as their genome. Correct Answer-B. are smaller, with fewer base pairs. Consider a mutation in which the change is from the codon UCU which encodes serine, to ACU which encodes threonine. Which type of point mutation is this? A. nonsense mutation B. frameshift mutation C. silent mutation D....
