tumor cells: tumor cells

Researchers from Harvard Medical School, Boston, and the Institute for Systems Biology, Seattle, have discovered that the remains of tumor cells killed by chemotherapy or other cancer treatments can actually stimulate tumor growth by inducing an inflammatory reaction. The study also reveals that a family of molecules called resolvins can suppress this unwanted inflammatory response, suggesting new ways to enhance the effectiveness of existing cancer therapies

Conventional, radiation- and drug-based cancer therapies aim to kill as many tumor cells as possible, but the debris left behind by dead and dying cancer cells can stimulate the production of proinflammatory cytokines, signaling molecules that are known to promote tumor growth.

“Dead and dying tumor cells are an underappreciated component of the tumor microenvironment that may promote tumor progression,” explained Charles N. Serhan, PhD, Director of the Center for Experimental Therapeutics and Reperfusion Injury at Brigham and Women's Hospital and Professor at Harvard Medical School. Serhan and colleagues therefore decided to investigate whether tumor cell debris can stimulate tumor growth.

A gene includes the sequence AGAACT. When it is transcribed, what will the RNA sequence be? A. UCUUGA B. UGCCGU C. UCUUTC D. TCT
Margaret [11]

Answer:

A

Explanation:

The correct option would be A.

<em>According to the base-pairing rule, Adenine (A) always pairs with Thymine (T) (or Uracil in the case of RNA) while Guanine (G) always pairs with Cytosine (C).</em>

Hence;

             A-U

            G-C

            A-U

            A-U

            C-G

            T-A

Therefore, AGAACT would be transcribed to UCUUGA.

What might happen to a protein if homeostasis is disrupted? why?
natka813 [3]
Disruption in protein homeostasis leads to the appearance and accumulation of intermediate nonnative conformations that tend to form oligomeric and aggregated species, which over time cause cellular injury..

Which structure is labeled X in the diagram below?
Vladimir [108]

Answer:

Option D

Explanation:

Diagram is attached.

Capsid protein is a form of structural protein which usually forms part of a complex which later produces protective shell around the nucleic acid in a virus. It is also referred to as coat protein or head protein.  

Capsid acts as a distinguishing feature for identifying an integrated viral genome, plasmids and other genetic material of viruses. In fact, viruses are termed as organisms that encode capsid proteins.  

Hence, option D is correct

Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.

Why would it be important to know the possible genotypic and phenotypic ratios of different genetic crosses?
OleMash [197]
It’s important to know the possible genotypic and phenotypic ratios of different genetic crosses because the the phenotype shows what the offspring will physically look like what the genotype is what genes the offspring carries. phenotype doesn’t always show what alleles the offspring carries because if the offspring is heterozygous for the gene only the dominant allele shows and the recessive allele won’t be visible. the genotype can see what alleles the offspring carries, both dominant and recessive. knowing the genotype helps to know what alleles are passed on. if one of the parents have a genetic mutation that is passed on, the phenotype helps see what ration of offsprings will have the mutation visible and the genotype will help see what ratio of offsprings will pass on the allele for the mutation
