Solid tumors are clusters of cancer cells and often contain blood vessels. When molecule B binds to the wild-type Brec protein i
Agata [3.3K]

The molecule C-P phosphorylates and thus activates D, whereas Kinase D amplifies cellular signaling by phosphorylating many substrates. In this case, it is expected to observe kinase D overexpression in Brec-MUT cells.

<h3>Cancer, phosphorylation and signaling pathways</h3>

Cancer can be defined as a multifactorial disease, which is often associated with uncontrolled cell growth.

Cancer signaling may be associated with defective pathways such as, for example, a mutated kinase protein that affects normal downstream molecular cascades.

A kinase is a specific protein that acts to phosphorylate specific cellular substrates, thereby activating/deactivating a particular signaling pathway.

Spanish influenza is thought to be caused by
s2008m [1.1K]

The "Spanish" influenza pandemic of 1918–1919, which caused ≈50 million deaths worldwide, remains an ominous warning to public health. Many questions about its origins, its unusual epidemiologic features, and the basis of its pathogenicity remain unanswered. The public health implications of the pandemic therefore remain in doubt even as we now grapple with the feared emergence of a pandemic caused by H5N1 or other virus. However, new information about the 1918 virus is emerging, for example, sequencing of the entire genome from archival autopsy tissues. But, the viral genome alone is unlikely to provide answers to some critical questions. Understanding the 1918 pandemic and its implications for future pandemics requires careful experimentation and in-depth historical analysis.

Cas9 cleaves both strands of the target DNA. Which of the following could occur when cells will try to repair the damage after c
Aloiza [94]

The correct answers are: the insertion of a DNA sequence into the targeted gene and deletions of the targeted gene

Cas9 is an enzyme endonuclease (which means it cuts nucleotides) that is part of the CRISPR-Cas9 complex- genome editing tool that can remove, add or alter sections of the DNA sequence.

Cas9 recognize the sequence that is going to be cut thanks to guide RNA- pre-designed RNA sequence complementary to sequence of interest. DNA repair machinery will try to fix the “damage” but it can add (insert) or delete some nucleotides.

The less abundant part of the solution is called the _________. (1 point) A. Solution B. Solvent C. Solute D. Mixture
dangina [55]
ANSWER:

C. Solute.

As stated in the definition of the noun solute, it is "the minor component in a solution." This means that it is the less abundant part of the solution.

Therefore, Option C ( solute ) is correct.
