a.

Neutrophils will not be able to phagocytose pathogens at the injury site.

b.

Neutrophils will not be attracted to the injury site.

c.

Macrophages will not be able to secrete signaling molecules.

d.
  1. Macrophages will not be attracted to the injury site.

    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...

    Please answer 2-5 2. Consider a gene with a particular function. Mutation X and mutation Y cach cause defects in the function of the encoded protein, yet a gene containing both mutations X and Y encodes a protein that works even better than the original protein. The odds are exceedingly small that a single mutational event will generate both mutations X and Y. Explain a simple way that an organism with a mutant gene containing both mutations X and Y...
