However, one daughter cell created by division of stem cells will not be immortal due to lack of telomerase expression. What difference will you expect in regulation of the telomerase coding gene between the two daughter cells produced by cell division of stem cells? How might the cells be different in terms of chromatin structure at that loci?arrow_forwardThe pre-mRNA transcript and protein made by several mutant genes were examined. The results are given below. Determine where in the gene a likely mutation lies: the promoter region, exon, intron, cap on mRNA, or ribosome binding site. a. normal-length transcript, normal-length nonfunctional protein b. normal-length transcript, no protein made c. normal-length transcript, normal-length mRNA, short nonfunctional protein d. normal-length transcript, longer mRNA, shorter nonfunctional protein e. transcript never madearrow_forward
- What could be a probable fate of the segment of the DNA strand encircled in red? Polypeptides can now be translated from the encircled region as the two antiparrallel strands separate. The encircled DNA region can now be used as a template for transcription. it will relax right away on its own so that helicase can separate the two complementary strands with much ease If the encircled region will not be relaxed by another enzyme, it will experience supercoiling and will most likely break.arrow_forwardYou made four mutants for a promoter sequence in DNA and studied them for transcription. The results of the amount of gene expression or transcription (based on beta-Gal activity shown on Y-axis) for these DNAs (X-axis) are shown. The sequence of the wild-type and mutant DNAs, and consensus sequence from many promoters are shown here for your convenience. From this experiment you can conclude that: Nucleotide substitution can identify important bases of the binding sites or promoter in DNA (e.g., -10 and -35 promoter sequences of lac operon).

- DNA polymerases are capable of editing and error correction, meaning it is able to edit and correct single base error so that the gene is not affected. However, RNA polymerase has a limited capacity for error correction. Given that a single base error in either replication or transcription can lead to error in protein synthesis, suggest a brief explanation for this difference in the capability of error correction between DNA polymerase and RNA polymerase.arrow_forwardYou isolate a mouse Tau-gene-containing DNA fragment from the chicken and hybridize it to the freshly-made and isolated hnRNA (primary transcript) from the nucleus of the mouse cells transcribed from the Tau gene (immediately after it was produced), allowing no time for processing of the hnRNA. Describe what you see when you look at the DNA/RNA hybrid molecule under the electron microscope.arrow_forwardProvide the type of cis acting sequence element or segmentsarrow_forward
- Briefly discuss (referring to the images provided) why mutant 2 fails to produce functional protein. Note that none of the mRNA transcribed from this gene is of the expected size; some of the mRNA molecules produced are 223 nucleotides shorter than expected, whilst others are 47 nucleotides longer than expected.arrow_forwardTransforming an Animal In order to create the transgenic cow, your lab first needs to create a DNA vector containing the insulin gene. This step involves a considerable amount of scientific terminology. Make sure you understand the meaning of key terms.
