Module 2 ike and tica, Questions and answers, 100% proven pass rate. Graded A. 2022/2023 The bacterial transformation experiments infecting mice with S and R strains (Griffiths 1928) and the pu ... rification of the transforming substance (Avery, McLeod, and McCarty 1944) demonstrated that - ✔✔DNA is the hereditary material. Bacteria can acquire hereditary information from their environment. Which of the following is true of the DNA template strand? - ✔✔The template strand is copied by RNA polymerase to make an RNA copy The Foxp2 protein is a transcription factor which binds to DNA at specific genes to cause them to be transcribed. Analysis of KE family DNA sequences identified a single nucleotide mutation in the FOXP2 gene located on chromosome 7 region 7q31 which correlated with the speech disorder. This single nucleotide change results in an amino acid change from an arginine to a histidine. Arginine is positively charged and has a long, linear side group. Histidine is sometimes positively charged, and sometime neutral, and has a bulky ring structure side group. The mutant Foxp2 protein cannot bind DNA. These two amino acids are shown below. Where in the Foxp2 protein do you predict this amino acid is located? - ✔✔In a region of the protein which binds to DNA; the mutation probably directly affects the ability of the protein to bind DNA Do operons have to have operators? - ✔✔nah When estrogen binds to the estrogen receptor: - ✔✔the estrogen-estrogen receptor complex activates transcription and the estrogen-estrogen receptor complex binds to estrogen-response elements A m [Show More]
