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
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
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.

Ticks
Ticks belong to a family called Acarina, which also contains mites. Ticks eat by taking blood from
other organisms such as wallabies, lizards, echidnas and occasionally humans. In humans this can
lead to symptoms such as itching, head aches and in extreme cases flu like symptoms, facial
paralysis, and meat allergy.
1. Identify the relationship a tick has with its host. Justify your answer [3]
Answer:
Parasitism
Explanation:
Parasitism is a form of relationship in which one of the organism is being harmed while the other benefits. The organism being harmed is usually called the HOST while the organism that benefits is called PARASITE. Parasites often inflict certain health-related conditions on their hosts.
According to this question describing the mode of feeding of ticks, they are said to eat by taking blood from other organisms such as wallabies, lizards, echidnas and occasionally humans, which are all HOSTS.
In human hosts, this relationship with ticks can lead to symptoms such as itching, head aches and in extreme cases flu like symptoms, facial paralysis, and meat allergy etc. From the description above, it is clear that TICK has a PARASITIC RELATIONSHIP with its host as it brings only harm to them and benefits itself.

B) How does fertilization increase genetic diversity in a diploid organism?
C) How does independent assortment increase genetic diversity during meiosis?
D) How many potential combinations result from chromosomes alignment during metaphase I?
E) How does chromosome methylation result in silencing specific genes during gamete formation?
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?

7. Apply: Look carefully at the picture below and you will see an insect called a
katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.
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.

3. Speed up chemical reactions, support cell's structure
4. Nucleic acids
Explanation:
The image comprising of a tabular representation portrays the four biological molecules, their building blocks and function. The four biological molecules in nature are carbohydrates, proteins, lipids and nucleic acids.
- Carbohydrates are biological polymers made up of monomers called monosaccharides. They function to store energy in cells for a short period of time. Examples are glucose, starch etc.
- Lipids are formed from monomers called FATTY ACIDS. They function in the long term storage of energy. Examples are phospholipids, fats etc.
- Proteins are formed from monomers called AMINO ACIDS. They provide various functions including speeding up of chemical reactions, provide cellular structure support etc. Examples are haemoglobin, melanin, hormones etc.
- Nucleic acids are polymers of NUCLEOTIDES. They function majorly in the storage of genetic information. Examples are DNA, RNA etc.
What are the advantages and disadvantages of the serial dilution-agar plate procedure?
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.
