8) Outline what you would need to know to answer the following question: of all the proteins that exist on earth at this time, w
Natalka [10]

Answer:

To solve this question, it is necessary to consider the number of protein structures that have been empirically verified and the number of Open reading frames predicted from sequencing data

Explanation:

The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher. Indeed, less than 5% of sequenced proteins have an empirically validated 3D structure.

What kind of solution causes chloroplasts to be pushed outward against the cell wall, isotonic, hypertonic, or hypotonic?
Elina [12.6K]
The answer to this question would be hypertonic.

If the chloroplast is going to be pushed against the cell wall, probably the water around the cell wall is decreased, causing it to suck up the water inside. Then, the solution must be causing the cell to lose water. The cell will lose water if put in a hypertonic solution. In a hypertonic solution, the osmotic pressure of the solution is higher than the cell, make it attract water from cells.
