WGU BIOCHEM, Top Exam Questions and answers, 100% Accurate, graded A+ What is the complimentary DNA sequence to this sequence 5' - ATC CTT TAG GTT-3' - ✔✔-5'-AAC CTA AAG GAT-3' Which answer ... choice displays the tRNA anticodon of the mRNA codon 5'- UGA-3'? - ✔✔-5'-UCA-3' What would be the resulting mRNA sequence from the template strand with this sequence: 5'-CAG CTC GTC-3' - ✔✔-5'-GAC GAG CUG-3' What is the coding strand DNA that would be made from this template strand? 5'-AAA TAC CGG GAT-3' - ✔✔-5'-ATC CCG GTA TTT-3' What is the coding strand sequence if the non-template strand sequence is 5'-AGC CTT TAA CTA-3' - ✔✔-3'-ATC AAT TTC CGA-5' Given this template sequence 5'-GAT TAA CGA-3' what is the corresponding mRNA sequence? - ✔✔-5' UCG UUA AUC-3 What is the complementary strand to the following DNA sequence 5'-GCC CGG TTA AGC-3' - ✔✔-5'- GCT TAA CCG GGC-3' The DNA sequence 3'-ATG ATC CTT-5' is part of the template strand during DNA replication. Which of the following would be the correct sequence for the newly made DNA? - ✔✔-5'-TAC TAG GAA-3' What is the complementary DNA strand for the DNA sequence 5'-ATT CGG GCT CCC -3'? - ✔✔-5'- GGG AGC CCG AAT-3' What is one direct effect of inhibiting translation? - ✔✔-The production of proteins would stop Which of the following is NOT part of mRNA processing prior to translation? - ✔✔-Promoters (this is part of transcription) tdahlke What is the function of DNA polymerase in the process of PCR? - ✔✔-It recognizes (not synthesizes) the primers and uses the available dNTPs to replicate the template DNA sequence Nonsense Mutation - ✔✔-Changes one amino acid to a Stop codon Missense Mutation - ✔✔-Changes one amino acid to a different one Insertions/Deletions of a codon - ✔✔-Alters the gene's reading frame causing a frameshift mutation Silent Mutation - ✔✔-One single base is changed but the amino acid stays the same Studies have shown that increased expression of two genes called SIRT1 and SIRT2 is associated with chronic exposure to cocaine and contributes to drug addiction, what difference in the regions of the SIRT1 and SIRT2 genes in ppl addicted to cocaine increase their expression? - ✔✔-The nucleosomes become more widely spaced. What scenario describes epigenetic regulation of the agouti gene? - ✔✔-Mother mice fed methyl-rich diets during pregnancy give birth to offspring with decreased agouti gene expression compared to those fed methyl-poor diet. Oxidative damage to DNA can often result in the alteration of a single nucleotide. Which DNA repair mechanism would repair this type of damage? - ✔✔-Base Excision Repair XP is a recessive genetic disease that occurs when one or more of the genes that perform nucleotide excision repair are nonfunctional. Why do XP patients have a much higher incidence of skin cancer that the general population? - ✔✔-The mutation rate of all other genes is higher due to failure to repair. What reaction is responsible for the formation of polypeptides. - ✔✔-Dehydration What reaction is responsible for the destruction/breaking of polypeptides. - ✔✔-Hydrolysi [Show More]
