Answer:
The correct answer is option c. "because the in vitro EGFR did not travel through the Golgi it was not properly tagged with the molecular modifications needed to localize to the membrane".
Explanation:
The epidermal growth factor receptor (EGFR) protein localization into the cellular membrane is a highly regulated process since the transmembrane part of the protein is very hydrophobic. The EGFR needs to go trough a series of post translational modifications in the Golgi apparatus, including glycosylation and subsequent folding processes. The EGFR synthesized outside the cells did not travel through the Golgi apparatus, therefore it does not go trough the post translational modifications and could not properly localize to the membrane.
Answer:
(A). Result in different amino acids to be read due to frame shifts
Explanation:
Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.
These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.
This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.
Thus, the correct answer is option (A).
B=book
a=backpack
b=50
b=2a-20
50=2a-20
2a=75

<span>because “Barrow is ground zero for climate-change science, and because we worry that climate change is shrinking the sea ice and we don’t know how that will affect the animals that depend on it. But at this time there is no effective plan if a catastrophe such as a ship collision or oil spill occurs. The Coast Guard hasn’t decided what its presence will be in the Arctic. Someone needs to monitor whats going on there.</span>
