General growth media serves the purpose of generating more bacteria colonies to create enough samples to identify to perform other tests. Differential media is used to differentiate species or subspecies of bacteria by how they differentially react to the dyes of chemicals in the media due to differences in metabolic properties of the different bacteria species.  An example of differential media is MacConkey agar.

After a recent experiment, a
bija089 [108]
Here's what he must do:

-- Run the experiment again, several times if possible.  Combine or analyze
the results of the several experimental runs in some statistically valid way.

-- Run the simulation again, several times.  Combine or analyze the results
of the several simulations in some statistically valid way.

-- Then, compare the analysis of several experimental runs with the analysis
of several simulations, in some statistically valid way, to decide whether they
<em>really</em> don't track.

-- If they do, then look for ways to tighten up the simulation so that maybe
they can track better.

-- If they don't, then he's back to <em>before</em> Square-1.  He not only has to
deal with the question of whether or not his experiment is valid, but he
also has to consider the possibility that his simulation is trash and
doesn't actually model nature like he expected it to.

How do you think a code consisting of so few characters can encode the instructions for building thousand of different proteins?
jok3333 [9.3K]

Answer:

Every gene has a code which is responsible for the formation of thousands of protein necessary for normal functioning of the cell.

Explanation:

In genes codes are present. In these codes have information about the formation of protein. Genes is just like a recipe book which contains information about making different types of protein which is necessary for the cell. So codes in the genes are work according to the instruction of the cell for making a specific protein. These codes contains characters which is sent by the genes to the ribosomes of the cell where protein are formed.
