How can transposons contribute to specific human diseases?.
Please give it quickly
To promote genetic diversity in bacteria, it has been found that some species have a genetic mechanism that allows them to increase
their mutation rate during DNA replication. A scientist hypothesizes that the functions of the following two enzymes would be impacted
by this mechanism. In each case, state if you agree and provide a reason for your answer.
i) DNA primase
ii) DNA polymerase III
Which of the followings statements are true about DNA polymerase?
1.) It can only go in one direction, meaning the lagging strand can't be synthesized continuously.
2.) It cannot start a DNA strand from scratch, so another enzyme is needed to create "primers" as a starting point.
3.) It cannot copy epigenetic marks (such as methyl groups) on its own; these must be "copied" onto the daughter DNA strand by other enzymes after DNA replication.
4.) All of the above

- Please read the scenario below and then answer the question (in bold) that follows. An original DNA sequence reads 3'- GGCGCTAGAATC -5'. A mutated version of that DNA strand is produced that reads 3-GGCTCTAGAATC -5. Based on the information above, how severe of an impact do you believe the mutation would have on the cell (and therefore individual) in which the mutation occurred? O a. Very severe, because the mutation leads to the formation of a truncated polypeptide O b. Moderately to very severe, because the mutation results in the formation of a polypeptide that contains amino acids not found in the unmutated polypeptide O c. Likely not that severe, because the amino acid sequence of the mutated polypeptide is identical to the amino acid sequence of the nonmutated polypeptidearrow_forwardUse the following information to answer the next question In the early part of the last century , biologists thought that proteins might be the camers of genetic information. It is now known that DNA is the genetic molecule in living organisms and that RNA cames genetic information in some viruses. Proteins are not suitable to be the genetic molecules within cells because they A.) are large organic compounds B.) are composed of building blocks called amino acids C.) do not replicate themselves D.) catalyze biochemical reactionsarrow_forwardResearchers can isolate a sample of cells, such as skin fibroblasts, and grow them in the laboratory. This procedure is called a cell culture. A cell culture can be exposed to a sample of DNA. If the cells are treated with agents that make their membranes permeable to DNA, the cells may take up the DNA and incorporate it into their chromosomes. This process is called transformation or transfection. Scientists have transformed human skin fibroblasts with methylated DNA and then allowed the fibroblasts to divide for several cellular generations. The DNA in the daughter cells was then isolated, and the segment that corresponded to the transformed DNA was examined. This DNA segment in the daughter cells was also found to be methylated. However, if the original skin fibroblasts were transformed with unmethylated DNA, the DNA found in the daughter cells was also unmethylated. With regard to the transformed DNA, do fibroblasts perform de novo methylation, maintenance methylation, or both?…arrow_forward

DNA ligase e. repliconarrow_forwardThere are 6 parts to this question: This is a follow up to the prior question regarding the replication of the DNA strand below. The DNA strand is here for your reference and you do not need to do anything with or to it. TC GATATCGG AGCTATAGCC c) what enzyme separated the parental DNA template strands, d) what bonds were broken? e) what enzyme replicates DNA f) before DNA can be replicated/copied, what must be laid down to allow the enzyme in "e" to replicated the DNA (be specific)? g) our DNA is replicated in many "pieces", what enzyme connects these many "pieces" into one continuous DNA strand that becomes the sister chromatid? h) during what specific phase of the cell cycle does this DNA replication process occur? (This should be a review question from last topics we covered).arrow_forwardWhich of the following statements about the processes of the central dogma is/are incorrect? I. Replication occurs only once during the life cycle of a cell. II. The entire sequence of a DNA molecule carries instructions for the synthesis of proteins and nucleic acids. III. The products of transcription all eventually undergo translation. IV. Transcription and replication both involve the use of RNA molecules. V. The translation of the genetic code is directly based on the sequence of the template DNA strand. O , I, and V O II, II, and V O l and IV O II, II, and IV O Only l is incorrectarrow_forward

- Some antibiotic drugs fight infection by interfering with DNA replication, transcription, or translation in bacteria. Indicate whether each of the following antibiotic drug effects is on replication, transcription, or translation. HINT Each answer (replication, transcription, and translation) is used only once for the following: a. Rifampin binds to bacterial RNA polymerase. b. Streptomycin binds bacterial ribosomes, disabling them. c. Quinolone blocks an enzyme that prevents bacterial DNA from unwinding.arrow_forwardthe human immunodeficiency virus HIV uses RNA rather than DNA to encode genetic information. During infection, however, HIV uses an enzyme known as reverse transcriptase to generate double-stranded DNA. Generally speaking, how would the enzyme generate a double strand of DNA from a single strand of RNA?arrow_forwardYou are studying RNA viruses and have discovered a new one that grows well in a culture of eukaryotic cells. You know that the virus is a single-stranded RNA virus, but you don’t know if it is plus or minus stranded. Your lab-mate says, “Well, just treat your cell culture with cyclohexamide and see if the virus replicates its genome.” You know that cyclohexamide inhibits protein elongation by binding to eukaryotic ribosomes. What is the basis of your lab-mate’s suggestion?arrow_forward
