Answer:
<h2> Mutant 4: can grow on minimal medium supplemented with T, P, or A.</h2>
Explanation:
In minimal medium, those bacteria who lacks some enzyme which are necessary for the synthesis of all their required compounds can not grow. They require these metabolites supplemented in minimal medium. In this case , if any of these 3 metabolites T,P,A which are required for the synthesis of H are absent in minimal medium,then there will be no bacteria growth.
<h2>Answer:</h2>
The correct answer is the option C.
Which is we add equal amount of salt in all the water samples.
<h3>Explanation:</h3>
- As in experiment we have to indicate that the boiling point of water increases with the addition of salt.
- Now we also know that water contains many salts as compared to the distilled water.
- So the boiling points of simple water and distilled water would be bit different.
- So we cannot choose one for our experiment. Instead we use all water samples of equal volume adding equal amount of salt in all samples.
- Then we will compare results for a net answer/result of experiment.
Muscle and nerve cells both contain the complete genome of the organism contained within their DNA. This means that both cells will contain all the same genes including the gene coding for the protein required in the sodium potassium pump. (Note the difference between cellular types and functions is the EXPRESSION of genes is different; all cells share the same genes but do not necessarily express them).
If both cells require the sodium/potassium pump and associated proteins than it is likely the exact same gene. Proteins are created through expression of genes. First the gene (a discrete section of DNA on a chromosome) is transcribed into an RNA message in the nucleus (RNA is similar to DNA and contains just the gene itself. Think of it as a post it note that has been copied from an encyclopedia of genes. Then the RNA is translated into a protein, which is a long chain of amino acids. The particular order and properties of the constituent amino acids that make up the protein cause it to coil up and form a 3 dimensional structure with properties that govern its particular function in the cell. In this case, the protein plays a key role in the sodium potassium pump. Protein synthesis is a fascinating topic and for more information, study up on the central dogma of genetics.
RNA interference is a mechanism of eukaryotic gene regulation. In this mechanism, the enzyme “dicer” cuts dsRNA into smaller fragments called siRNA, which form a complex with RISC and degrade specific RNA.
siRNA or small interfering RNA as a part of RISC complex finds and binds to complementary mRNA and it induces the cleavage of mRNA. This causes degradation of that mRNA. This is the way RNA interference prevents translation.
true because they are driven by the ATP made by the light-dependent reactions. Both systems shut down in the dark. The light-independent reactions can last a little longer if there is ATP remaining in the chloroplast.
