Researchers use affinity chromatography, using beads coated with chains of poly-deoxythymidine (poly-dT) to isolate certain RNA molecules. The desired RNA will stick to the beads while unwanted RNAs will flow through the column. The retained RNA can then be eluted. What RNA species can be purified using this method? solvent flow 1 bead with covalently attached poly-dT desired RNA species other RNAS pass through Eukaryotic rRNA Both, the eukaryotic and bacterial mRNAs ō ō Ō Bacterial mRNA Eukaryotic mRNA

Answers

Answer: The RNA species that can be purified using affinity chromatography with beads coated with poly-deoxythymidine (poly-dT) are the mRNA molecules, both eukaryotic and bacterial. The poly-dT chains specifically bind to the poly-adenine tail present in most messenger RNAs, allowing them to be selectively retained while other RNAs flow through the column. Eukaryotic rRNA would not be purified by this method, as it does not contain a poly-adenine tail.

Explanation:

The RNA species that can be purified using affinity chromatography with beads coated with chains of poly-deoxythymidine (poly-dT) are eukaryotic mRNA.

An immobilised ligand and its binding partner engage in a specific binding interaction, which forms the basis of the separation technique known as affinity chromatography. Examples include interactions between an enzyme and a substrate, an enzyme and an inhibitor.

This is because eukaryotic mRNA molecules have a poly-A tail at their 3' end, which can bind to the poly-dT chains on the beads. The other RNA species, such as eukaryotic rRNA, bacterial mRNA, and bacterial rRNA, do not have a poly-A tail and therefore will not bind to the poly-dT chains.

As a result, these unwanted RNAs will flow through the column while the desired eukaryotic mRNA will stick to the beads. The retained eukaryotic mRNA can then be eluted from the beads using a solvent.

Answers

The conditions that are necessary for natural selection to occur within a population of S. aureus are physical traits that differ, heredity, reproduction, and variation in the number of offspring produced. So options 1, 2, 4, and 5 are correct.

There are two parts to Natural Selection: the non-random component and the random component. The non-random component is selection pressure. For example, predators will want to eat the prey. The random component is adaptation. For example, the prey will try to avoid predators.

Natural selection affects populations in response to current conditions, so species survival in future and unpredictable conditions is not necessary for natural selection.

Answers

The virus creates new viral components by utilizing the host cell. The host cell is infected by the bacteriophage virus in two ways: both the lysogenic and lytic cycles.

Virus cell :

In the lytic cycle, the bacteriophage infuses its hereditary material into the host, utilizes its replication apparatus and repeat and kills the host cells because of lysis of the microbes. The prophage is formed when the virus's genetic material is incorporated into the host's and formed during the lysogenic cycle. This prophase is replicated along with the bacterial genome by offspring. New viral components like the caps id and others are made from this genetic material.

Apply what you have learned about gene flow, genetic drift, mutation, and recombination in order to analyze and evaluate their effects

Answers

The following are the effects of each:

Gene flow: Also called gene migration, is the introduction of genetic material (by interbreeding) from one population of a species to another, consequently altering the gene pool of the recipient population

Genetic drift: It is the arbitrary change in the population's frequency of a gene variation that already exists. Gene variations may fully vanish due to genetic drift, which would limit genetic variety.

Mutation: Genetic mutations are modifications to your DNA sequence that arise as your cells divide and generate duplicates of themselves. It leads to variation and better adaptation of the organism to its environment.

Recombination: Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This creates genetic diversity at the level of genes that reflects variations in the DNA sequences of different organisms.

The difference between the mode of reproduction between pteridophytes and angiosperms

Answers

Pteridophytes reproduce by spores, while angiosperms reproduce by seeds.

What are spores and how do pteridophytes reproduce using spores?

Spores are small, single-celled reproductive structures that can develop into a new organism under the right conditions. Pteridophytes reproduce by spores, which are produced in specialized structures called sporangia. The spores are released into the air and can be carried to new locations by wind or other means. When conditions are favorable, the spores germinate and grow into new pteridophyte plants.

How do angiosperms reproduce by seeds?

Angiosperms reproduce by seeds, which are produced inside fruits. The flowers of angiosperms contain male and female reproductive structures. Pollen from the male structure (the anther) fertilizes the egg in the female structure (the ovary), and the fertilized egg develops into a seed. The seed contains an embryo and a food supply, enclosed in a protective seed coat. When conditions are favorable, the seed germinates and grows into a new angiosperm plant.

A Grizzly bear has 42 sharp, long teeth. They have big, flat molars for grinding since they are omnivores. They have huge 5 digit paws, and their foreclaws are longer and straighter than their hindclaws. Grizzly bears require powerful paws since they travel only on their paws.

Although death affects density momentarily, the relationship between mortality rate and density is complicated due to the impacts of age ratios and density dependency on vital rates.

if trybutyrin agar is not used within a few days of making it, it will lose its opacity. considering this,l why is it useful to have a positive and a negative control?

Answers

The use of tributyrin agar is essential for ensuring accurate and reliable results in biological experiments. It is important to have both a positive and negative control in any experiment involving tributyrin agar because the positive control is used to confirm that the test is working properly, while the negative control is used to ensure that the results are specific to the enzyme being tested.

A positive control is a sample of agar that has been prepared correctly and is used to prove that the experiment is working correctly. It is used to compare the results of the experiment to a known and expected outcome. A negative control, on the other hand, is a sample of agar that has been deliberately prepared incorrectly. It is used to show what happens when the experiment is not successful.

By having both a positive and negative control in an experiment, researchers can determine whether the results obtained are reliable. If the results of the experiment match the expected outcome of the positive control, then it is likely that the results are accurate and the experiment was successful. If, however, the results match the expected outcome of the negative control, then it is likely that the experiment has failed and the results should be discarded.

In conclusion, it is essential to have both a positive and negative control in any experiment involving tributyrin agar. This ensures that the results are reliable and not compromised by the degradation of the agar over time.
