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.
im pretty sure its adaptation <3
Answer:
Explanation:
The aim of the Hershey and Chase experiment was to show that DNA and not proteins are the genetic material.
Proteins are made up of amino acids which also has a nitrogenous base. Since the whole point of the experiment was to differentiate between the two i.e. show which one is the genetic material, it would be impossible to differentiate between DNA and proteins if the nitrogenous base was labelled.
Below statements are true:
<span>Acetylation of histone tails is a reversible process.

</span><span>DNA is not transcribed when chromatin is packaged tightly in a condensed form.
</span><span>Methylation of histone tails in chromatin can promote condensation of the chromatin.
</span><span>Some forms of chromatin modification can be passed on to future generations of cells.</span>
When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness.
