Answer:

Gene therapy

Explanation:

Gene therapy can be defined as the methodologies used to modify/restore the expression of target genes and thus cure and treat genetic disorders. Gene therapy approaches consist of delivering specific nucleic acids (either RNA or DNA) in the cells of the individual to be treated. Some of the most important gene therapy approaches include the use of small interfering RNAs (siRNAs) in order to block target gene expression, adenovirus vectors to insert genes into host cells, the use of the CRISPR-Cas9 genome editing system to insert specific sequences by the mechanism of homologous recombination, etc.

Answer:

4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work

Explanation:

Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.

The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.

Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.

What are the two benefits of using Punnett Squares?

harina [27]

Explanation:

They are useful as they can predict the genetic probability of a particular phenotype arising in a couple's offspring. In other words, it can tell you if you will or will not have a certain trait.

What is the overall equation for photosynthesis

never [62]

Answer:

The Photosynthesis Equation. The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Meiosis ensures the transmission of traits from one generation to the next. At the same time, it is a key process that introduce

liraira [26]

The question is incorrect so the answer consists of the genetic context of meiosis.

Answer:

Two main types of cell division are mitosis and meiosis. Meiosis is the process of cell cycle division in which the parents cell divides into the four daughter cells. This division is also known as reductional division.

In meiosis, the gametes are haploid where as the parent cell is diploid in nature. The cell undergoes the two meiosis division, the first division is reductional in nature whereas the second meiosis division is same as the mitotic division. This division occurs in the sex cells and results in the formation of haploid gamete hat restores deiploidy during fertilization process. Crossing over during meiosis bring variation in the cells.
