4. Drugs such as AZT work by inhibiting the function of reverse transcriptase. Integrase Strand Transfer Inhibitors (INSTI) are a class of antiretroviral drugs designed to block the action of integrase. Sketch a model showing how AZT and INSTI work.
AZT and INSTI (Integrase Strand Transfer Inhibitors) both are inhibiting drugs.
What is the mechanism of working AZT and INSTI?In place of thymine, reverse transcriptase substitutes AZT into the developing DNA chain. But, AZT is unable to form the required phosphate bond with the following nucleotide because it possesses a 39 azido group rather than a 39 hydroxyl group.
After incorporating themselves into viral DNA, nucleoside reverse transcriptase inhibitors (NRTIs) prevent reverse transcription by triggering chain termination. Some medications must be intracellularly phosphorylated in order to be effective.
Thus, this is how AZT and INSTI work.

Which structure can be found in both eukaryotic and prokaryotic cells?A) mitochondrionB) nucleusC) chloroplastD) nucleic acid
The correct answer is (D) Nucleic Acid. Nucleic acid is a structure found in both eukaryotic and prokaryotic cells. Nucleic acids, such as DNA and RNA, are essential biomolecules.
Both eukaryotic and prokaryotic cells contain nucleic acid in the form of DNA or RNA, although the organization and location of these molecules differ between the two cell types. In prokaryotic cells, the nucleic acids are usually found in the cytoplasm, while in eukaryotic cells, the DNA is contained within the nucleus.
Other structures, such as mitochondria, nuclei, and chloroplasts, are exclusive to eukaryotic cells.

Early researchers therefore easily deduced that a triplet (three-base) code would be the simplest combination of As, Cs, Gs, and Us that could encode all 20 amino acids in RNA.
There are 64 potential options in a triplet combination, or codon (four nucleotides at each of three places = 4 4 4). There are 64 different triplets that make up the language of DNA. Although DNA is double-stranded, only one of these two strands is employed to form an mRNA transcript for each protein.

Systemic circulation begins when the oxygen rich blood leaves the heart and travels to all parts of the body through three types of blood vessels.
The given statement is true.
As oxygen-rich blood exits the left ventricle of the heart and enters the aorta, the body's biggest artery, systemic circulation starts. The blood then flows via smaller arteries, arterioles, and finally into capillaries, the tiniest blood vessels in the body. Capillaries exchange oxygen and nutrients with the body's tissues.

how was it determined that dna carries genetic information
The determination that DNA contains genetic information was made by a series of scientific experiments over the course of many years.

They found that the substance responsible for changing bacterial genetic traits was DNA. This was discovered by combining a certain strain of bacteria that could break down a specific sugar with a strain of bacteria that was unable to do so.
Further investigation led to the discovery that DNA contains the genetic information necessary for the production of proteins in living things.
The double-helix model of DNA, which was created in 1953 by James Watson and Francis Crick, described how the structure of DNA contained genetic information in the form of four bases.

Write a procedure that will demonstrate the role of yeast in fermentation using the following materials: distilled water, bakers yeast, dextrose/glucose/sucrose, plastic water bottle, beaker, hot plate, graduated cylinder, balloons, and funnel.
Answer:
Here is a procedure that demonstrates the role of yeast in fermentation using the materials listed:
Materials:
- Distilled water
- Bakers yeast
- Dextrose/glucose/sucrose (one of these sugars)
- Plastic water bottle
- Beaker
- Hot plate
- Graduated cylinder
- Balloons
- Funnel
Procedure:
1. Start by measuring out 100 mL of distilled water using the graduated cylinder and pouring it into the plastic water bottle.
2. Add 1 gram of baker's yeast to the water in the bottle and stir gently to mix.
3. Next, add 5 grams of dextrose, glucose, or sucrose to the bottle using the funnel.
4. Gently swirl the bottle to mix the yeast and sugar with the water.
5. Place the balloon over the mouth of the bottle, making sure it is securely attached.
6. Set the bottle aside in a warm, dark place for at least 30 minutes to allow fermentation to occur.
7. While waiting for the fermentation to occur, fill the beaker with water and place it on the hot plate to heat.
8. Once the water in the beaker has reached a boil, turn off the hot plate.
9. Carefully remove the balloon from the mouth of the bottle and use the graduated cylinder to measure the volume of gas that has been produced in the bottle. Record this value.
10. Carefully pour the hot water from the beaker into the plastic water bottle and swirl to mix.
11. Quickly replace the balloon over the mouth of the bottle.
12. Observe the balloon and record any changes in size or shape that occur over the next few minutes.
13. Dispose of the contents of the bottle in a proper manner.
Explanation:
In this procedure, the role of yeast in fermentation is demonstrated by combining yeast, sugar, and water in a bottle and observing the production of gas (carbon dioxide) as a result of the fermentation process. The balloon placed over the mouth of the bottle allows the gas to collect and be measured. Heating the bottle after the fermentation process speeds up the chemical reaction and causes an increase in gas production, which is observed by the expansion of the balloon.

The first rib is quite small. Like all the ribs, it's angled downward from back to front.
The thorax is commonly known as the chest. The thorax expands in a dome-shaped pattern to roughly two thirds of its full width from the first to the third rib. The thorax spreads a bit more, forming a cone-shaped structure, from the third rib to the seventh. The thorax somewhat narrows and the ribs significantly shorten between the seventh and the twelfth ribs.
