DNA replication is semi conservative, which allows each of the 2 strands to serve as a template for the new strands Correct Answer true Recall that the DNA polymerase must bind a double-stranded po... lymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? Correct Answer RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as frame shift mutations, including both insertions and deletion. Which repair pathway would be used to repair this type of damage? Correct Answer Nucleotide Excision Repair Maternal smoking during pregnancy is hazardous yet common in many places. Many studies have associated prenatal smoking to unhealthy physical and psychological outcomes for the baby. Researchers know that maternal smoking affects are epigenetic in nature. Which event can be considered epigenetic in nature? Correct Answer Changes in chromatin structure Blood is what type of inheritance? Correct Answer co dominance What is the probability that a child will have an autosomal dominant disease if their father is heterozygous for the allele and their mother is homozygous for the normal allele? Correct Answer 50% What is the complementary DNA strand for the DNA sequence 5'-ATT CGG GCT CCC - 3' Correct Answer 5'- GGG AGC CCG AAT - 3' A research scientist is trying to create a new strain of bacteria that can produce a protein needed for her research. What molecule will act as a template in creating the new protein? Correct Answer messenger RNA (mRNA) What is 1 direct effect of inhibiting translation? Correct Answer the production of proteins would stop How many amino acids, and which ones, would be encoded by the following mRNA sequence: 5'- AUGACUCCCGGG -3' Correct Answer 4: MET, THR, PRO, GLY Promoters are DNA sequences near the start of a gene that are recognized by transcription factors which recruit RNA polymerase to that gene for expression. This is an important aspect of transcriptions but not part of the mRNA processing. Correct Answer true [Show More]
