Answer:
a. The guide RNA (gRNA) is transcribed from the PML 104-9RNA1 plasmid vector
b. It is correct. The homology-directed repair (HDR) fragment of interest enters into the cell and is then inserted at the site of the original double-strand breaks (DSBs) via the HR DSB repair pathway.
c. plasmid, nucleus, cytoplasm
d. Once Cas9 is transcribed, this nuclease forms a complex with the gRNA and cuts the target DNA, thereby inducing a DNA double-strand break (DSB) which is repaired either by non-homologous end joining (NHEJ) or homology-directed repair (HDR)
Explanation:
The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas (i.e., CRISPR-associated protein 9) is a natural prokaryotic defense mechanism against foreign viral invaders. In genome engineering, this system has been adapted to create a versatile RNA-programmable genome editing technique. Cas9 is an RNA-guided endonuclease capable of recognizing and cleaving a target DNA complementary to the guide RNA (gRNA). The gRNA is a specific RNA sequence formed by two small RNAs (crRNA and tracrRNA), which binds to the Cas nuclease enzyme and guides the gRNA-Cas9 complex to the target DNA sequence.

Does the temperature increase during melting?
Explain why
Answer:
Melting is the process where the atoms of a rigid solid Crystal lattice held by strong bonds, are broken down which increases the degree of locomotion of these atoms which characterises the liquid state.
The energy that breaks these bonds is heat energy ( latent heat of fusion ), hence temperature increases

What is the importance of testicular self exam
Answer:
Testicular self-exam is important because it helps detect abnormalities, especially cancer. Physicians don't check the testicles as much, so it is important to self-exam more often. Testicular cancer is more likely to be found if checked monthly. Besides cancer, routine exams create a feel for the characteristics of the testicles and would be easier to detect a sudden change.

Answer:
1. Nucleus ---> present in both plant and animal cells
Cell membrane ---> present in both plant and animal cells
Cytoplasm ---> present in both plant and animal cells
Golgi apparatus ---> present in both plant and animal cells
Mitochondria ---> present in both plant and animal cells
Vacuole ---> present in both plant and animal cells
Ribosome ---> present in both plant and animal cells
Endoplasmic reticulum ---> present in both plant and animal cells
Lysosome ---> present in animal cells only
Nucleolus ---> present in both plant and animal cells
Explanation:
2. The common organelles present in both plant and animal cell include the nucleus, cytoplasm, cell membrane, mitochondria, ribosome, etc. The presence of these common organelles is due to the fact that that these organelles help both plants and animal cells to carry out the basic functions of life. Also, plant and animals cells are both eukaryotic cells.
3. Plant cell differ from animal cells due to some specialized functions they carry out like photosynthesis, as well as some structural differences in plant cells. Plants cells have chloroplasts which are organelles responsible for photosynthesis in plants. Plant cells also have a large central vacuole unlike animal cells which help to maintain turgidity in plants. Cellulose cell wall in plant cell also serve to maintain the rigidity and give shape to the plant as well as to protect the plant cell.
Explain where the carbon stored in fossil fuels comes from.
Answer: Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources.

I will mark who ever has this correct Brainliest ( for this question the points will be 85 )
From the following, the example which is not of a cnidarian is Snail. Hence, the correct option is C.
What are Cnidarians?Cnidarians are the radially symmetrical soft bodied animals that belong to phylum Cnidaria of the animal kingdom. They are also called coelenterates. The snails belong to phylum mollusca.
They are all sea dwelling animals which have a hollow digestive cavity. Furthermore, they appear in either sessile polyp stage or moving medusa stage. Moreover, they are further divided in classes Schyphozoa, Anthozoa, Hydrozoa and Cubozoa. All having different characteristics.
They show both sexual and asexual reproduction. Also, their development is indirect, meaning the development takes place from a larval stage. They show the property of polymorphism and have cnidoblasts cells for defense. Hence, the correct option is C.

The complete sequence of nucleotides in the human genome would fill more than ___________ books!
Answer:
The complete sequence of nucleotides in the human genome would fill more than 3000 books.
Explanation:
Genome corresponds to the set of genes that determine the morphological and functional characteristics of living beings.
In the human, the genome consists of the total sequence of nucleotides found in the DNA, contained in the cell nucleus, and distributed in the 23 pairs of chromosomes it possesses.
In the nucleus of a human cell there are about 3,200,000,000 DNA nucleotides, without taking into account the nucleotides of the mitochondrial genome, just over 15,000.
According to this, the amount of books that could be filled with the information of the human genome is estimated at 3,000 books.
Which of the following cell types is formed by meiosis? A. muscle cells B . sperm cells C. skin cells D. blood cells
Answer: B
Explanation: The rest are produced through mitosis.
A type of cell that is created during the process of meiosis is known as a sperm cell. Thus, the correct option is C.
What is Meiosis?Meiosis can be defined as the type of the cell division which goes through or in which two daughter cells has been produced from the parental cell that has not genetically identical to their real parental cell. Meiosis has been also known as the reductional division.
The germ cells must be generally produced by the process of the meiosis. It is because these cells has been usually contain half of the amount of the genetic material as it is compared to the parental cell. After producing these gametes, the cells has undergo through the process of the fertilization in order to produce the product known as zygotes which contain the genetic material of both males and females.
Therefore, sperm cells and egg cells are the types of cells that are created during the process of meiosis.
