Based on your understanding of nucleic acids, what type of bonds form between the CRISPR/guide RNA molecule and the target DNA
Answer:
The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds
Explanation:
The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.

10. Most cells are microscopic. Very few, like the eggs we eat, are visible to the unaided eye. Why have cells evolved to be small versus very large structures visible to the human eye
Answer: Efficient functioning.
Explanation:
Cells require a lot of substances to both come into and leave the cell in order for the cell to accomplish it's functions. These substances can be anything from carbohydrates to water and they come into the cell through diffusion and osmosis.
The thing about diffusion however, is that it happens faster over shorter distances than longer distances. This is why cells are so small. They evolved to be that size to ensure that diffusion of these substances takes place relatively quickly so that they can use these substances to carry out their functions at a faster rate.
Passive membrane transport processes include ________. movement of a substance down its concentration gradient movement of water from an area of low concentration to an area of high concentration consumption of ATP the use of transport proteins when moving substances from areas of low to high concentration
Answer:
movement of a substance down its concentration gradient
Explanation:
As you may already know, the plasma membrane of a cell has a semi-impermeable nature. This means that the plasma membrane allows only a few very specific substances to pass in and out of the cell. This movement of subtlety can happen in a passive or active way. In an active way, the moment is made through proteins of the membranes. Passively, the movement is made through a concentration gradient, where the substance is able to pass from the more concentrated side to the less concentrated side.

How many molecules are in 3Hg(SO)4
Answer:
1.806 × 10²⁴ molecules
Explanation:
From the chemical compound given in this question, there are 3 moles of Hg(SO)4.
To calculate the number of molecules in 3 moles of Hg(SO)4, we multiply the number of moles by Avagadro number (6.02 × 10²³)
number of molecules = 3 × 6.02 × 10²³
= 18.06 × 10²³
= 1.806 × 10²⁴ molecules
Changes in ecosystems are most pronounced when humans remove which species?
Answer:
Of course predators consume prey, but in doing so, they may have broader impacts on communities as a whole. That is to say, predators help to maintain a balance among organisms, both by consuming prey and by altering prey behavior and prey habitat selection. This article describes how predators influence the composition and distribution of species in communities.

A car accelerates from 4 meters/seconds to 16 meters/second in 4 seconds.The car’s acceleration is blank meter/second2
Answer:
3m/s²
Explanation:
a = v - u/t
Where;
a = acceleration (m/s²)
v = final velocity (m/s)
u = initial velocity (m/s)
t = time (s)
According to this question, a car is said to accelerate from 4 m/s to 16m/s in 4 seconds. This means that;
v = 16m/s
u = 4m/s
t = 4s
a = 16 - 4/4
a = 12/4
a = 3m/s²
¿A qué se refiere la sexualidad libre de coerción y violencia?
Para las mujeres y las niñas, el derecho a controlar su propio cuerpo y su sexualidad sin ningún tipo de discriminación, coerción o violencia es fundamental para su empoderamiento. Sin derechos sexuales, no pueden realizar sus derechos a la autodeterminación y la autonomía, ni pueden controlar otros aspectos de sus vidas. De hecho, son los intentos de controlar la sexualidad de las mujeres y las niñas los que dan como resultado muchos de los abusos de los derechos humanos que enfrentan a diario, incluida la violencia de género, el matrimonio forzado, la mutilación genital femenina y limitaciones en su movilidad, vestimenta y educación. , empleo y participación en la vida pública. Lo mismo ocurre con las lesbianas, los hombres gay, las personas bisexuales, las personas transgénero, las trabajadoras sexuales y otras personas que transgreden las normas sexuales y de género y que, como resultado, enfrentan un mayor riesgo de violencia, estigma y discriminación. Está claro: los derechos sexuales sustentan el disfrute de todos los demás derechos humanos y son un requisito previo para la igualdad y la justicia.
A nivel mundial, existe un gran debate sobre si definir los derechos sexuales y cómo hacerlo. IWHC cree que para superar algunas de las barreras políticas al reconocimiento, respeto, protección y cumplimiento de los derechos sexuales, necesitamos aclarar cuáles son.
IWHC, en colaboración con otras organizaciones líderes de derechos humanos y salud sexual, ha desarrollado la siguiente definición de trabajo de derechos sexuales:
Los derechos sexuales abarcan ciertos derechos humanos que ya están reconocidos en las leyes nacionales, documentos internacionales de derechos humanos y otros documentos de consenso. Se basan en el reconocimiento de que todas las personas tienen derecho, libres de coerción, violencia y discriminación de cualquier tipo, al más alto nivel posible de salud sexual; perseguir una vida sexual satisfactoria, segura y placentera; tener control y decidir libremente, y con el debido respeto a los derechos de los demás, sobre asuntos relacionados con su sexualidad, reproducción, orientación sexual, integridad corporal, elección de pareja e identidad de género; ya los servicios, educación e información, incluida la educación integral en sexualidad, necesarios para ello.
