in dna sequencing, how does the addition of dideoxynucleoside triphosphates (ddntps) terminate the synthesis of new dna? group of answer choices
in dna sequencing, how does the addition of dideoxynucleoside triphosphates (ddntps) terminate the synthesis of new dna is
The ddNTPs have a hydrogen instead of a hydroxyl group at the 3' end, which prevents the addition of nucleotides.
What is dideoxynucleoside triphosphates (ddntps)?
Dideoxynucleoside triphosphates (ddNTPs) stop the bio-polymerization of DNA and are a crucial chemical part of DNA sequencing technology, which is a fundamental tool for molecular biology research today. By detecting the terminated DNA fragment following a single labeled ddNTP incorporation into DNA under PCR conditions, radiolabeled or fluorescent dye labeled ddNTP analogues are utilized in this method to sequence DNA.
Pyrrolidine nucleoside triphosphates (prNTPs), a novel amino-functionalized ddNTP analogue that was rationally designed, was synthesized in this study along with their polymerase activity with DNA polymerase as measured by LC-MS and Gel-electrophoretic methods.
The incorporation of prNTPs into DNA oligonucleotides with Therminator DNA polymerase as similar control substrate ddNTP is clearly supported by the Mass and PAGE studies. As a result, the prNTP incorporation with polymerase functionalizes the DNA oligonucleotide as an amine group. As a result, prNTPs offer ways to make desired conjugated DNA with other biomolecules, dyes, or fluorescent compounds without changing the structure of the nucleobase.

You are searching for a mutant cell that is defective in protein glycosylation. You would most likely find such a mutant by looking for cells with defective ___________.
You are searching for a mutant cell that is defective in protein glycosylation. You would most likely find such a mutant by looking for cells with defective Golgi apparatus.
The Golgi apparatus can be described as a stacked membrane that plays an important role in the modification of proteins inside a eukaryotic cell. A protein after translation needs to be packaged and processed in order for it to move out of a cell. The Golgi apparatus is the site where protein modification and packaging occur.
One of the most important modifications after the translation of proteins that occurs in the Golgi complex is the glycosylation of proteins. If a cell has a mutation due to which protein glycosylation is being affected, then this means that there is a problem with the functioning of the Golgi apparatus due to this mutation. In such a circumstance, a mutant cell with a defective Golgi apparatus needs to be found.

Water makes up approximately 60% of the human body and plays a vital role in regulating body temperature. Which property of water allows it to prevent large fluctuations in body temperature?.
Water has a high heat capacity, or the ability to "hold on to" heat well; this property aids in the regulation of body temperature in both organisms and cells. Sweating is another way that water can be used to cool down an overheated organism.
Warm-blooded animals employ water's high heat capacity to more efficiently distribute heat throughout their bodies.Water works like a car's cooling system, moving heat from warm to cold areas and allowing the body to maintain a more constant temperature.The body requires water to maintain temperature because it is a good heat conductor and absorber. Water can absorb a lot of heat before its temperature increases because of its large heat capacity. This characteristic enables the water to function as a buffer against abrupt temperature changes in every cell of the human body.Learn more about water here:

A root cell may continue to absorb minerals even though the concentration of the minerals is greater inside the cell than in the soil. This absorption is accomplished mainly by active transport.
Molecules move in and out of a cell through the semi-permeable cell membrane. There are some movements that occur along the concentration gradient and do not require energy. On the other hand, there are other movements, such as active transport, that occur against the concentration gradients, from a region of lower concentration to a region of higher concentration which require energy.

O
B. Air temperature decreases.
C. Air temperature does not change.
D. Air temperature depends on the amount of organisms in the area.
Sry I didn’t know what subject to do for this question cause there was no earth science
The correct option is B.
The air temperature decreases when altitude increases.
When there is an increase in elevation, there will be less amount of air above us. Thus the amount of pressure decreases. Since the pressure decreases, air molecules will be spreading out further due to the expansion of air, and gradually the temperature decreases.
There will be variations of temperature with altitude which will as in the case of the troposphere, the temperature will decrease due to increasing altitude. In the stratosphere, the temperature will be increasing generally as the altitude increases due to the greater absorption of ultraviolet radiation by the ozone.
The basic idea of decreasing air temperature with respect to increased altitude is that as so far away you get from the space of earth, the atmosphere gets thinner. The total heat content included in a system is directly related to the amount of matter present, so due to this, it is cooler at increased elevations.

relationship between lactobacillus bulgaricus and streptococcus thermophilus under whey conditions: focus on amino acid formation
The discussion of relationship between lactobacillus bulgaricus and streptococcus thermophilus under whey conditions: focus on amino acid formation is given in the below paragraph-
In this study, we used Lactobacillus delbrueckii subsp. bulgaricus 2038 grown with or without Streptococcus thermophilus in whey medium to conduct microarray experiments to examine how these two strains use nitrogen since Lb. bulgaricus 2038 uses whey as its nitrogen before casein. Because S. thermophilus primarily preferred different types of peptides than L. bulgaricus, but has lost the ability to prioritize the use of free branched-chain amino acids, L. bulgaricus 2038 was better able to import the types of peptides required for growth compared to monoculture.
In order to stop Lb. bulgaricus 2038 from converting aspartate into intermediates that form the carbon skeleton, which is catalyzed by phosphoenolpyruvate carboxykinase, the ratio of nitrogen to carbon was reduced during co-culture.

rang, c. u., peng, a. y. and chao, l. 2012. bacterial aging requires an extrinsic damage agent. microbiology 158:1553–1559
The correct answer is Because bacterial ageing is believed to result from non-genetic (e.g. oxidative) damage.
Streptomycin, which produces mistranslated proteins that are more susceptible to oxidation, was found to be capable of inducing both damage and ageing in bacterial populations. There was a dose effect relating the level of damage to the concentration of streptomycin. All of the studies that did not find evidence of bacterial ageing did not use a damaging agent. However, fluorescent proteins were used as a visual marker in all studies that were successful in finding evidence. In those studies, ageing was caused by an extrinsic factor, such as the proteins themselves or the excitation light. As a result, all previous studies can be reconciled, and bacterial ageing is a real phenomenon. However, studying and observing bacterial ageing necessitates the addition of an extrinsic damage agent.

A) It can be poured.
B) It can expand to fill its container.
C) It cannot be compressed.

Correct Option is (C) It cannot be compressed. It is well known that there are powerful intermolecular forces of attraction holding molecules together in solids. As a result, they are immobile from their starting position but are capable of vibrating in their average position.
As a result, the molecules in solid substances have minimal kinetic energy. However, compared to solids, the intermolecular forces of attraction that hold the molecules together in liquids are weaker. They are able to slip past one another as a result. They therefore possess medium kinetic energy.
Vander Waal forces, which are weak, hold the molecules together in gases. As a result of their high kinetic energy, they travel quickly from one location to another, which causes more collisions.
