Answer:

An allergic reaction

Explanation:

An allergic reaction occurs when our immune system misinterprets a harmless substance into a harmful antigen and initiate an over-expressed immune response against it. Some of these allergic substances are pollen, molds, insect stings, etc.

These allergens trigger the production of IgE antibodies in the body which interact with different cell and initiate the release of chemicals like histamine that cause symptoms of allergic reaction.

It can affect the nose, skin, lung, stomach lining, etc. Therefore the correct answer is an allergic reaction.

The scientists mapping the SNPs in the human genome noticed that groups of SNPs tended to be inherited together, in blocks known
Over [174]

Answer:

SNPs have shown that only 0.1 % of DNA sequences are different in the human genome between different individuals, thereby all the inherited phenotypic variation observed in our species is associated with only 0.1 % of differences at the genome level  

Explanation:

Haplotypes are block-like sequences of DNA that are inherited together due to low recombination rates. Moreover, single-nucleotide polymorphism (SNP) mapping is a very useful methodology used to map the site of SNP mutations (i.e., SNP variants). In this regard, it has been observed that there are approximately 10 million common SNPs in the human genome. These SNPs contribute to the wide range of phenotypic variation observed in human populations for different traits (e.g., eye color, hair, weight, height, etc). Moreover, researchers have determined that SNPs can be clustered into haplotypes, thereby haplotypes can be accurately sampled by as few as approx. 300,000 selected SNPs, which are sufficient to represent all of the genetic variation across different human genomes.

Scientists’ understanding of the role and function of DNA has built up over time. How did the findings from Hershey and Chase’s
mr_godi [17]

Answer:

Hershey & Chase concluded. after the experiment that the genetic material that is passed from virus to the bacteria is not the protein coat but DNA. It proves the DNA is the genetic material and not the protein.

After labelling the Phage DNA and protein, Hershey and Chase performed a series of experiments like infection, blending and centrifugation. Hershey and Chase gave full evidence of the DNA being a genetic material by their experiments. To perform the experiment, Hershey and Chase have taken T-2 bacteriophage (invaders of E.coli bacteria).
