Being able to understand the relationship between DNA, mRNA, tRNA, ribosomes and proteins, is necessary for any researcher inter

ested in gene therapy. Gene therapy is dedicated to correcting genetic defects by replacing mutated genes with wildtype versions. This can include complete removal and replacement of the entire gene (knock-outs or knock-ins) or removal of only the actual mutated nucleotides. Sickle Cell Disease is an example of a single-point mutation: GAG becomes GTG, which codes for a new amino acid. One would only need to replace a single base to correct the disorder making it very amenable to gene therapy. The mutant sickle cell allele is called HbS (for sickled hemoglobin) while the wt allele is HbA. Philippe Kasongo, a masters student from Oxford is studying for an oral exam on gene therapy, and has an especial interest in the disorder since he comes from the Democratic Republic of Congo where Sickle Cell has a historical high rate of occurrence due to the prevalence of malaria. Oral exams are a feature of certain British schools where students form a line and have to answer a series of questions from their proctor rather than take a written exam. Should we try oral exams at Lehman this semester

Answer:

Yes.

Explanation:

Yes, we should try oral exams at Lehman this semester in order to fulfill the research on gene therapy done by the masters student. Test is to evaluate the performance of the student in the class, it can be taken by both the methods i.e. through written or through oral exams. Both have the same significance because both evaluate the performance of the students so we can try oral exams instead of written exams at Lehman this semester to help the masters student in his research.

schepotkina [342]

Answer: No

Explanation: It is beneficial if the animals that are disadvantageous doesn't reproduce so it doesn't discredit natural selection. The traits in which variation is occured are more suitable for organism to live and reproduce in the environment are preserved and are passed from generation to generation.

However, natural selection effects limited number of progeny.

Which of the following best describes the significance of the TATA box in eukaryotic promoters?
ankoles [38]

Answer:

The correct option is A.

Explanation:

TATA box refers to a  non coding sequence of DNA that is found in the promoter regions of eukaryotic genes. The TATA box serves as the binding sites for certain proteins and some transcriptions factors in eukaryotic genes; it signifies the points where transcription begins. Transcription is the process by which the genetic information in DNA is replicated into an mRNA. This is the first step in protein synthesis.  The name TATA was derived from the nucleotide bases that are always present in large number a the site. T stands for thymine while A represents the adenine base.
