The answer to your question is Tendons.
Answer:
This is an English Language question and I need to choose the most appropriate option.
The answer is Option E
Explanation:
Option A is incorrect because 'each of which' is supposed to be followed by a singular verb 'is' and not 'are'. 'When' is used incorrectly here.
Option B is incorrect because 'which' is not introducing an meaningful non-defining clause in the statement. It is referring to the shark's jaws. The first two clauses are not connected to 'which'.
Option C is incorrect. 'Each one of which are ready' should be 'each one of which is ready'. It is also referring to the shark's jaw.
Option D is Incorrect. The use of a present continuous verb 'lying' is incorrect. The first clause also has not meaning.
Option E is correct.
Answer:
The correct answer is ''can change over time in response to environmental cues, allowing genes to be turned on or off as needed.''
Explanation:
Histones are a family of proteins involved in compacting DNA into structural units called nucleosomes. Histone modifications occur in response to environmental conditions, and modulate the structure of chromatin, that is, they alter the structure of nucleosomes and therefore chromatin, and thus activate the transcription process, in which the chromatin is in the euchromatin state (loose conformation, in which the DNA information can be read), or "off" state, in which the chromatin adopts the heterochromatin conformation (compact conformation, which prevents reading), respectively. These post-translational modifications are mainly acetylation, methylation, phosphorylation, although there are many others. These make up the “histone code” that can change the expression pattern of some genes by modifying the chromatin structure, activating or silencing these genes.
