What are the advantages and disadvantages of the serial dilution-agar plate procedure?​

Answers

Answer:

Advantages

- Serial dilution is used in microbiology to estimate the concentration or number of cells/organisms in a sample to obtain an incubated plate with an easily countable number of colonies.

- In biochemistry, serial dilution is used to obtain the desired concentration of reagents and chemicals from a higher concentration.

- In pharmaceutical laboratories, serial dilution is performed to receive the necessary concentration of chemicals and compounds as this method is more effective than individual dilutions.

- In homeopathy, homeopathic dilutions are used where a substance is diluted in distilled water or alcohol. It is believed than dilution increases the potency of the diluted substance by activating its vital energy.

Disadvantages

- An error might occur during the propagation of the sample, and the transfer inaccuracies lead to less accurate and less precise transfer. This results in the highest dilution to have the most inaccuracies and the least accuracy.

- Because serial dilution is performed in a stepwise manner, it requires a more extended period of time which limits the efficiency of the method.

- Serial dilution only allows the reduction of bacteria/cells but not the separation of bacteria/cells like in other techniques like flow cytometry.

- This technique also requires highly trained microbiologists and experts in aseptic techniques.

The ADG1(ADP glucose pyrophosphorylase 1) is involved in flowering timing in plants. You are interested in developing a DNA probe using partial protein sequence information. Part of the amino acid sequence is Glu-Glu-His-Asp-Val-Leu 1. determine the possible antisense oligo nucleotides possible from this amino acid sequence 2. How many total unique different oligonucleotide would need to be produced to cover all possibilities

Answers

Answer:

1)  UUC-AUG-AUC-AAG-UAA.

2) 48

Explanation:

1) Determine the possible antisense oligo nucleotides possible from this amino acid sequence

Given that the peptide sequence is = Glu-Glu-His-Asp-Val-Leu 1.

we will use a codon table to show the codons and Anticodons for each of the Amino acids  

Amino Acid   Codons                                                         Anticodons

 Glu                GAA, GAG                                                    UUC, CUC

 His                 CAU, CAC                                                    AUG, GUG

 Asp         GAU, GAC                                                    AUC, GUC

 Val                 GUU, GUC, GUA, GUG                             AAG, GAC, UAC,CAC

 Leu   UUA, UUG, CUU, CUC, CUA, CUG  | UAA, CAA, AAG, GAG,UAG,CAG

From the table above

The possible antisense oligo nucleotide sequence is : UUC-AUG-AUC-AAG-UAA.

2)  How many total unique different oligonucleotide would need to be produced to cover all possibilities

A desired peptide sequence requires 16 anticodons

Hence the total unique different oligonucleotide needed to be produced to cover all possibilities = 16 *3 = 48

The ADG1(ADP glucose pyrophosphorylase is involved in flowering timing in plants and a DNA probe is made by using partial protein sequence information. Part of the amino acid sequence is Glu-Glu-His-Asp-Val-Leu.

1. To determine the possible antisense oligonucleotides possible from this amino acid sequence:

Since, for every amino acid, there is a specific codon and anticodons are present so according to the given information, the possible antisense oligonucleotides for Glu-Glu-His-Asp-Val-Leu is UUC-AUG-AUC-AAG-UAA.

2) The total number of unique different oligonucleotides that would need to be produced to cover all possibilities is 48

since the amino acid sequence is Glu-Glu-His-Asp-Val-Leu has 16 anticodons and each anticodon have 3 nucleotides so the possible number of oligonucleotides are  :

16×3 = 48.

What are codon and anticodon?

A codon is a trinucleotide sequence of RNA that corresponds to a specific amino acid.

An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA sequence.

Thus, according to codon and anticodon, the possible antisense oligonucleotides for Glu-Glu-His-Asp-Val-Leu is UUC-AUG-AUC-AAG-UAA and a number of unique different oligonucleotides that would need to be produced to cover all possibilities is 48.

19. Fresh poultry should be rejected when:

A. It has been shipped in plastic wrap
B. It is slightly sticky to the touch
C. There is no discoloration
D. The receiving temperature is 38°F

Answers

Answer:

B

Explanation:

Fresh poultry should be rejected when the receiving temperature is 38°F. Therefore, option (D) is correct.

Poultry must be stored and transported at or below 40°F to guarantee food safety and inhibit the proliferation of harmful bacteria. Exposure to unsafe temperatures during storage or transportation can increase the risk of bacterial contamination and foodborne illness if the receiving temperature exceeds the threshold.

Indicators like plastic wrap during shipment, slight stickiness, or lack of discoloration do not necessarily imply safety concerns or spoilage with fresh poultry, as mentioned in the other options.

katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.

Answers

Answer: This description is an example of camouflage adaptations.

Explanation:

The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.

E) How does chromosome methylation result in silencing specific genes during gamete formation?

Answers

According to the random arrangement of homologous chromosomes in the equatorial plane, the correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?

How does the random arrangement of tetrads occur?

During metaphase 1, chromosomes' homologous pairs migrate to the equatorial plane. Once there, they randomly aline facing their kinetochores to the opposite poles.

The random arrangement of tetrads is different in every cell going through the meiosis process. This is because there is no equal alinement between two cells.

When tetrads arrange in the equatorial plane, there is no predetermined order. Each homologous chromosome of each tetrad faces any of the poles and then migrates to it while separating. Each of the chromosomes has two possibilities for orientation at the plane.

When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell.

This random order in the equatorial plane is what introduces variation into the gametes.

The correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?
