"ricin inhibits the functioning of ribosomes. What part of protein synthesis would be affected by ricin? What effect would this

have on a cell's ability to synthesize proteins?"

Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.  

They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.  

This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.

What happens to the chemical properties of a substance when it becomes part of a mixture?
Andreyy89

When a substance becomes part of a mixture, its chemical properties ONLY change if the resulting mixture is homogeneous. Otherwise nothing happens to the properties.


Explanation:

The formula of a selected pure substance doesn't amendment simply because it becomes a part of a mix. Chemical properties can amendment in a very mixture. If you've got a mix of water and alcohol, the melting point are below 0C. That doesn't mean that water now not freezes at 0C, it simply means that the mixture of water and alcohol doesn't freeze at 0C.

A scientist separates a population of lizards into two groups. what would most likely increase the rate of speciation in this po
eimsori [14]
<span>If the population is separated long enough, this means that random sampling in mating and reproduction, that occurred in the initial population has been restricted</span><span>. The two population will, therefore, adapt to their local environments and become reproductively isolated with time. After long periods of time, the two lizards population will have different alleles and will not be able to mate and produce viable offsprings hence will have speciated.</span>

Methylene blue reductase why were you told to cap the tubes tightly?
guajiro [1.7K]
The methylene blue reduction test is a test commonly used to estimate the microbial load of a milk sample and as a result, examine the quality of the milk.

The principle of this test is that methylene blue is a dye which loses its colour in the absence of oxygen. Bacterial metabolism can cause the depletion of oxygen in the milk, therefore the methylene's reduction rate is connected to the presence of microorganisms in the milk.

As a consequence, if the tubes were not sealed tightly, then oxygen will enter the tube and the dye's colour will diminish, giving a false result concerning the presence of microorganisms in the sample.
