1.) A certain Drosophila protein-coding gene has one intron. If a large sample of null alleles (null alleles are mutations that destroy the function of the protein) of this gene are examined, will any of the mutant sites be expected in thea) exons?b) introns?c) promoter?d) intron-exon boundary?Please justify your answers. Yes/no is not sufficient2)A linear fragment of DNA is cleaved with the individual restriction enzymes HindIII and SmaI and then with a combination of two enzymes. The fragments obtained are:HindIII - 2.5kb and 5 kbSmaI - 2kb and 5.5kbHindIII and SmaI - 2.5kb, 3kb and 2kbFollowing digestion, the products are run on an electrophoresis gel.Please draw the uncut figure of the above DNA sequence containing the two restriction sites.Please draw a representative gel picture (containing the products from the 3 digestion reactions and the uncut fragment) based on the above information.3.) The effect of base-pair substitution mutations on protein function varies widely form no detectable affect to the complete loss of protein function (null allele). Why do the functional consequences of base-pair substitution vary so widely?
Calcium Polycarbophil is calcium salkt of polyacrylic acid cross linked with divinyl glycol. But what is its forumla.
Illustrate four organelles or structures that all eukaryotic cells have in common. In adding, describe two eukaryotic cell features that would be found only in autotrophic cells.
Was evolutionary pressure that contributed to the echinoderm nervous system development likely due to selection for those animals capable of forward locomotion?
In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele. If a dwarf female from a pure line is crossed with a pink male from a pure line, Determine the phenotypic ratios in the F1 and F2 in..
A person is heterozygous for a mutation in a STAT gene replaces a tyrosine in coding sequence with a phenylalanine. The missing tyrosine is normally phosphorylated by a JAK bound to a cytokine receptor.
Joe Average has just been frightened by a very loud noise as he was taking a very difficult physiology exam. In response, his adrenal glands have released a large amount of adrenaline into his circulation. Which of the effects would you expect to ..
