Nostrana [21]

Answer:

3212

Explanation:

Transport vesicles are vesicles that function to carry molecules from one cellular compartment to another. The coat protein complexes I and II (COPI and COPII) are conserved pathways that transport proteins from the endoplasmic reticulum to the Golgi apparatus. Moreover, clathrin is a protein implicated in the formation of coated vesicles. The ADP-ribosylation factor GTPase activating (Arf GAP) proteins play a major role in Arf signaling pathways, which are responsible for uncoating of the COPI coat. On the other hand, COPII vesicles are known to retain their coats until they are recognized by tethering complexes, and whose formation is regulated by the GDP-GTP cycle of the small GTPase Sar1. Finally, the 70-kDa heat shock proteins (HSP70) are chaperones which function as uncoating ATPases to remove clathrin from coated vesicles after endocytosis.

Sloan [31]

The statement 'many scientists helped developed it over many decades'  describes the development of our understanding of DNA and inherited traits.

<h3>What is the DNA?</h3>

Deoxyribonucleic acid or DNA is a double helix molecule that stores the genetic information inherited across generations.

This molecule (DNA) contain genes and regulatory sequences that indicate the specific proteins an organism can produce.

In conclusion, the statement 'many scientists helped developed it over many decades'  describes the development of our understanding of DNA and inherited traits.

Complete Question:

Which statement best describes the development of our understanding of DNA and Inherited traits?

  • A. Scientists working in the 17th century discovered it.
  • B. Many Scientists helped develop it over many decades.
  • C. Frederick Griffith figures it all out in 1928.
  • D. One scientist working alone discovered it over a few years
