Data shows results of an experiment which was added to each peptide to culture the TRAP. Mutants of S. aureus and culture of the Agr. mutant of s. aureus.
Peptide 1 and three blocks Agr pathway
Peptide 2 blocks TRAP pathway
This is because the mutants are already blocked for one of the pathways.
Therefore it gives way to determine which pathway each peptide act on.

Estimating Population Size – Review the two approaches to estimating population size and answer the following questions.
Andre45 [30]

Answer:

b) there are 56 deer in 1000 acres of area.

Explanation:

If a person has 1000 aces of land and a local wildlife biologist tell him that on every 18 acres only one deer is present so in 1000 acres there are 56 deer are present.

calculation;

1 deer ------ 18 acres

x --------- 1000 acres

by cross multiplication, we get

18 x = 1000

both side divided by 18, we get

x = 55.5

by rounding off we get

x = 56

Genetically modified organisms are those organisms in which certain gene is inserted to get the desired beneficial results.

Explanation:

A genetically modified organism is an organism or plant altered for beneficial traits which would not have been possible by the traditional mating process or recombination techniques.

Genetic engineering is the technique involved for the construction of gene of interest and inserting them in the host species for getting expressed.

Many fruitful results have come out like a tomato of long shelf life k/a flavr savr.

Apart from molecular techniques used for cloning, CRISPR is the recent innovation which had made it very simple.

The GMOs can solve the food problem of the world as Single-cell proteins and longer shelved life food.

Disease resistant plants can be formed for better yields.

Nutrition level of food can be increased.

Example of GMO are canola, corn, papaya, soy and many animals are also on the list.

Animals cannot synthesize tyrosine from shikimate-3P because they lack EPSP synthase. However, tyrosine is listed as a non-essen
Marina86 [1]

Tyrosine is listed as a non-essential amino acid because it can be synthesised from the essential amino acid phenylalanine.

<u>Explanation:</u>

Amino acids are classified as essential and non essential according to whether they can be synthesized in the body itself or should be supplied by the diet. Essential amino acids cannot be synthesized in the body of the organism and thus can be obtained only from the diet. In the case of human beings, valine, phenylalanine, methionine etc are examples of essential amino acids.

Non essential amino acids can be synthesized within the body of the organism. Thus they need not be supplied by the diet. Alanine, aspartic acid etc are some of the non essential amino acids in human beings. It is given here that animals cannot synthesize tyrosine from shikimate-3p due to the lack of EPSP synthase.

But the amino acid tyrosine can be synthesized from the amino acid phenylalanine which is an essential amino acid. Thus tyrosine will be a non-essential amino acid.
