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 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...

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...

OCR Biology A Level (Full) Test Questions With All Correct Answers Which factors affect evolution? - CORRECT ANSWER Mutation, natural selection, sexual selection, gene flow and genetic drift What is a mutation? - CORRECT ANSWER Change in the sequence of bases in DNA What are the three ways the base sequence can be altered? - CORRECT ANSWER Substitution, deletion and insertion What is the term for a mutation where only one nucleotide is affected? - COR...

Mutation a change in the genetic material of a cell; cause by a mistake during DNA replication. Gene Mutations changes to a single gene. Point Mutations - involve changes in one or a few nucleotides/bases. involve changes in one or a few nucleotides/bases. Substitutions one base is changed to a different base (May or may not affect the amino acid). Insertions adds a new base to the DNA sequence Deletions removes a base from the DNA sequence Framesh...
