Frameshift mutations - Study guides, Class notes & Summaries

Describe the differences between deletion, insertion, substitution, and nonsense mutations. Provide an example of each using the following piece of DNA: TAC CAG ATA CAC TCC CCT GCT ACT. Indicate if any of the mutations are frameshift, nonsense, or missense mutations. correct answersMutations occur when a base sequence of DNA is permanently changed (Tortora, Funke, & Case, 2016). Mutations can either be harmful to an organism or beneficial depending how it alters a cell and its activity. A delet...

Biol 230 Exam 2 Questions and Answers Already Passed What makes cell same or different? - ️️ Different cell types have the same gene, protein makes cell different. What is central dogma (a.k.a. gene expression)? - ️️ genetic information (DNA strand) is transcribed into RNA and then translated into proteins What is exon? - ️️ RNA sequences in the primary transcript that are found in the mRNA What is intron? - ️️ 1.a non-protein coding 2.RNA sequences between exons that are...

• DNA = phosphate + deoxyribose sugar + A/T/C/G o Contains two strands. The strands are antiparallel (opposite each other). o 5’ → 3’ 3’ ← 5’ • RNA = phosphate + ribose sugar + A/U/C/G o Single strand, can fold back onto itself and form pairs between itself (stem‐loop). • Each nucleic acid is made up of polymers (many monomers) that are called nucleotides. o Nucleotides contain one or more phosphates, a five‐carbon sugar, and a nitrogen base. o Nucleotides are alway...

A nurse recalls the basic components of DNA are: - a phosphate molecule, deoxyribose, and four nitrogenous bases Which of the following mutations have the most significant effect on protein synthesis? - Frameshift mutations The base components of DNA are: - A, G, C, and T A DNA strand has a region with the sequence ATCGGAT. Which of the following would be a complementary strand? - TAGCCTAG A biologist is explaining how RNA directs the synthesis of protein. Which process is the biologist ...

Question 1 Which type of mutation does not change an organism's phenotype despite changing its genotype? Possible Answers: Frameshift Missense Silent Nonsense Correct answer: Silent Question 2 What would be an immediate consequence for a cell with a mutant version of DNA polymerase III that has lost its proofreading function? Possible Answers: Cancer EXAM Inability to complete the cell cycle Inability to replicate DNA A higher rate of mutations during replication Correct answer: A higher r...

WGU Biochemistry Exam (Latest 2023 - 2024) New Full Exam Questions and Answers ( Included ) 100% Correct 1. DNA replication is , which allows each of the two strands toserve as a for the new strands. Answer onservative, template: DNA replication is semiconservative, meaningthat each new duplex has one original (parent) strand and one new strand. Because the two parent strands are separated during replication and the base pairing is predictable, each parent strand can serve as a templ...

When explaining cancer that extends to organs or tissues distant from the site of origin, what term should the nurse use? A) Apoptosis b) Benign C) Metastasis D) Malignancy correct answers Metastasis What would the nurse expect to occur when a patient's cancer is caused by mutations of a proto-oncogene? A) Apoptosis B) Increased cell division C) Production of monoclonal antibodies D) Decreased cell responsiveness to growth factors correct answers Increased cell division A patient...

DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands - true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? - RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as frameshift mutations, includ...
