Answer:
The most important challenge that the scientific community has to face is to develop a vaccine that effectively targets some of the proteins encoded by SARS-CoV-2.
Explanation:
It has been shown that SARS‐CoV-2 encodes for 27 different proteins. These proteins include 4 structural (among them, the spike glycoprotein, responsible for the pathogenicity of this virus), 15 nonstructural, and 8 proteins that have auxiliary functions (Liu et al. 2020). From the emergence of this disease, the scientific community has worked to understand how the immune system responds against specific protein regions of SARS-CoV-2 (i.e., antigen regions) by targeting and inactivating the virus.

Answer: B
Explanation: By most estimates, catalytic converters fitted inside the exhaust pipe of a gasoline-operated car convert over 90% of hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) from the engine into less harmful carbon dioxide (CO2), nitrogen and water vapour.
Answer:
The strands of the hybrid helix are less complementary than the original helix.
Explanation:
Complementary DNA strands are bonded to each other through hydrogen bonding. The nitrogenous base adenine (A) forms 2 hydrogen bonds with thymine (T). Guanine forms 3 hydrogen bonds with cytosine. Due to the presence of 3 hydrogen bonds, GC rich regions of DNA or RNA are more strongly bonded.
Therefore, if the two strands will be less complementary or contain more AT rich regions, the double helix will denature or melt at a lower temperature.
