The gel below shows a result of the experiment you designed using the DNA of three different individuals (S1-S3). It also shows a negative (C-) and a positive (C ) control, as well as a DNA marker. Why did S2 have three bands

Answers

Answer 1

Restriction enzymes recognize specific nucleotidic sequences. The molecule with no recognition site will not be digested. Individual S2 probably had molecules with the recognition site and others with a different sequence.

--------------------------

A restriction enzyme is a degradative polymer that recognizes and cuts up specific nucleotide sequences in DNA.

Restriction enzymes can produce cohesive cuts or blunt (abrupt) cuts, depending on the recognition sites.

The frequency in which the restriction enzyme will produce the cuts depends on the recognition sequences and the number of bases that compose them.

So restriction enzymes cut DNI molecules into different short sequences of varying lengths.

These pieces are called minisatellites and exhibit the existing variation from one person to the next.

These short sequences can be separated by using gel electrophoresis and will express a pattern of differentiation.

When the nucleotidic sequence of the DNA molecule does not include the recognition site, the enzyme will not cut this fragment. The enzyme does not digest this molecule.

Since the negative control does not have a recognition site, it is not digested by the enzyme.

The positive control is digested, meaning that these molecules carry the recognition site.

Probably DNA molecules from individual S1 do not have the recognition site either.

The enzyme recognizes the sequence in DNA from individual S3 and cuts it into two fragments.

The lane of Individual S2 includes both options: digested and not digested DNA. This means that the sample taken from this individual included DNA

                               ⇒  carrying the sequence, and

                               ⇒  not carrying the recognition sequence.

So enzymes digest molecules carrying the recognition sequence, and the other ones remain undigested.

Probably, individuals S1 and S3 are h0m0zyg0us, while individual S2 is heter0zyg0us.

Which two structures engage to create a muscle contraction?.

Answers

Muscle contraction occurs when actin connects with myosin.

Muscle contraction occurs thanks to an action potential, which transmits a stimulus to the interior of the muscles.

For fiber tension to occur, the myosin head must bind with actin, slip, release, and then connect with another actin.

This electrical signal allows the actin and myosin proteins to move, thereby generating contraction of the muscles.

Therefore, we can conclude that myosin is a protein found in muscle fibers in order to bind to actin protein and cause muscle contraction.

este fenómeno?

Answers

La troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

En la capa de la troposfera, que es la capa más baja de la atmósfera, hay vapor de agua, dióxido de carbono, metano y algunos otros gases que son responsables de la absorción de la radiación infrarroja. Parte de la radiación infrarroja se escapa al espacio, pero una parte es detenida y absorbida por los gases de efecto invernadero presentes en la atmósfera.

Esta absorción de radiación infrarroja por los gases de efecto invernadero contribuye a un aumento de la temperatura de la superficie de la tierra y de la atmósfera. Entonces, podemos concluir que la troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

what factors determine if a species is fit to survive?

Answers

Answer: variation, reproduction, and heritability.

Explanation:  Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.  

All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.

Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.

Crabs, pilchards, blennies and snappers are considered as secondary consumers because they feed on primary consumer which feed on producers such as plants and algae. Secondary consumer are those organisms which feed on herbivorous organisms or primary consumers.

They can feed on producers due to different digestive system so we can conclude that crabs, pilchards, blennies and snappers are the examples of secondary consumers.

Which of the following is an advantage of sexual reproduction?
A. Produce identical copies of an organism.
B. Produce natural variation to adapt to environmental change.
C. Quickly populate a new habitat.
D. Reproduce very quickly.

Answers

Answer:

B

Explanation:

Produce natural variation to adapt to environmental change is an advantage of sexual reproduction. Correct Option is 2.

The advantage of sexual reproduction is that it produces genetic variation within a population. During sexual reproduction, offspring inherit a combination of genes from both parents, leading to unique genetic combinations. This genetic diversity results in natural variation among individuals within a population.

This variation is advantageous because it allows a population to better adapt to changing environmental conditions. In a changing environment, some individuals may possess traits that are better suited to the new conditions, making them more likely to survive and reproduce. Through natural selection, these advantageous traits can become more prevalent in the population over time, enhancing the population's overall ability to adapt and thrive.

Answers

Answer:

Viruses used in gene therapy are retroviruses, adenoviruses, adeno-associated virus, herpes simplex, and vaccinia. Retroviruses are most commonly used because they can incorporate their genetic material into the host cell’s DNA, thus changing the genetic component of that cell.

Explanation:

Gene therapy is a medical field which focuses on the genetic modification of cells to produce a therapeutic effect or the treatment of disease by repairing or reconstructing defective genetic material. The first attempt at modifying human DNA was performed in 1980 by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990. It is thought to be able to cure many genetic disorders or treat them over time.
