Answer #1

Gene 1 is trascribed in the early stages and it works toward building RNA polymerasa, mutations in gene 1 makes the strain faulty at RNA polmerasa, this leads to late genes to express early, this late genes are realtade to toxicity and normaly would remain silent until further on in the infection

    1. Explain how some patients who are homozygous for the sickle-cell allele do not develop sickle-cell crisis or other symptoms of the disease. Because of a mutation to a regulatory gene, a variant form of the beta subunit is expressed that does not cause sickling of hemoglobin protein. Because of a defective regulatory gene, fetal hemoglobin is expressed in adulthood which compensates for defective adult hemoglobin. Because of an additional mutation to the gene for the beta subunit of hemoglobin,...

    Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dystrophin. The dystrophin protein itself is 3684 amino acids in length. Calculate below the approximate size of the mRNA that encodes dystrophin. Approximately what percentage of the gene that encodes dystrophin is intron sequence? The human genome encodes a much greater variety and number of proteins than the...

    Question: Answer whether 1 and 2 is forward or reverse genetics for the fill in the blank. 1. Abstract 1 (Döring et al., 2019) The evolution of C4 photosynthesis proceeded stepwise with each small step increasing the fitness of the plant. An important pre-condition for the introduction of a functional C4 cycle is the photosynthetic activation of the C3 bundle sheath by increasing its volume and organelle number. Therefore, to engineer C4 photosynthesis into existing C3 crops, information about genes...
