Answer:

CRISPR can also be used to make precise changes such as replacing faulty genes – true genome editing – but this is far more difficult. Customised Cas proteins have been created that do not cut DNA or alter it in any way, but merely turn genes on or off: CRISPRa and CRISPRi respectively.

What is the basic physical principle that chromatography is based upon
Sliva [168]

Chromatography is a laboratory technique for the separation of mixture. It contains two components:

Stationary phase- substance that is fixed inside the column

Mobile phase- substance that is moving through the column.

Analyte is the mixture that has to be separated by chromatography.

When both are added to the column, mobile phase and analyte, components of the analyte will adhere to the stationary phase at different level and as a result travel at different speeds through the stationary phase as the mobile phase flows through it. The components that adhere more strongly to the stationary phase travel more slowly compared to those with a weaker adhesion. So, chromatography separate substances based on their adhesion for stationary phase.

Why does the mitochondria make carbon dioxide during cellular respiration
blagie [28]
<span>Because the organelle undergoes process that converts biomolecules into a useful energy resource for cell activities that leaves the formation of carbon dioxide as an excess agent.
Mitochondrion is an important organelle in most living organisms because it is where biochemical processes of living organisms such as respiration takes place. The mitochondrion has a smooth outer membrane but a larger inner membrane. The inner membrane is about 70% protein and is very convoluted because that can even fit inside the outer membrane. Mitochondrion is the carrier of the Kreb's cycle in the matrix and it is responsible for the transfer of electron chain found in the cristae of the inner membrane.

</span><span>In the presence of oxygen, one glucose molecule has the energy to make up to 38 ATP. The ATP production is determined by the following steps, (-2 ATP) glycolysis preparatory phase, (7-9 ATP) glycolysis pay-off phase, (5 ATP) oxidative decarboxylation of pyruvate and (20 ATP) Krebs cycle. One glucose which has 38 ATP hence was the summation of all the process mentioned that took place.  All these process take place under the cellular function of cellular respiration.<span> </span></span>
