The correct answer is D. Without capsids, viruses could not replicate
Explanation:
A viral infection is caused as a virus enters the body and this replicates inside it by using the host's cells. This is possible through the capsid which is an external layer in the virus that provides protection to it and helps the virus replicate because the capsid is essential for the virus to attach and penetrate the host's cells to replicate. According to this, if a drug damages the capsids the virus could not replicate and this should or reduce the infection caused by the virus. Thus, a drug that damages capsids helps treat a viral infection because "without capsids, viruses could not replicate".
The option are not given and the options are:
Proteins are denatured by breaking covalent bonds.
Linear molecules like DNA are inherently stable.
Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.
The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.
Answer:
The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.
Explanation:
Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.
DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.
A convincing explanation of why some lineages survived while others vanished is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction.
<h3>What is an
asteroid?</h3>
One of the smaller planets in the inner Solar System is an asteroid. Asteroids are metallic or rocky bodies without an atmosphere, ranging in size from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.
The majority of the one million or more known asteroids are concentrated in the main asteroid belt, which is 2 to 4 AU from the Sun and between the orbits of Mars and Jupiter. The three categories of asteroids that are typically recognized are C-type, M-type, and S-type.
These were given their names and are frequently associated with, respectively, carbonaceous, metallic, and silicaceous compositions. The largest asteroid, Ceres, has a diameter of over 1,000 km (600 mi), making it a dwarf planet.
