Ribonucleic acid (rna) and additional deoxyribonucleic acid (dna) surrounds genes. in a process called methylation, they enhance, silence, or alter genetic instructions.
<h3>What is DNA methylation?</h3>
- Adding methyl groups to the DNA molecule is a biological process known as DNA methylation. Methylation has the ability to change a DNA region's activity without changing the sequence.
- When DNA methylation takes place at a gene promoter, it frequently decreases gene transcription.
- DNA methylation plays an important role in a number of critical processes in mammals, including aging, cancer, X-chromosome inactivation, genomic imprinting, and transposable element repression.
- The majority of eukaryotic genomes contain DNA methylation, a dynamic epigenetic alteration. It is well recognized to cause a high rate of CpG to TpG mutations.
- However, nothing is known about the connection between the rate of germline mutation and the dynamics of methylation during germline development.

Answer:
The correct answer would be a) circulatory system.
A stroke is primarily caused due to reduced or interrupted supply of blood to the brain.
The blood supply is usually reduced as a result of blockage or bursting of an artery carrying blood to the brain.
Consequently, the brain cells experience a lack of oxygen and nutrients due to which they begin to die.
Thus, stroke is initially caused by damage to the circulatory system.

Answer:
Pump Ca+ into the cell.
Explanation:
The pumps are used for the transportation of substances against the concentration gradient. These pumps require energy for the transportation of molecules against the concentration gradient.
The most common pump used for the transportation of calcium ions is the calcium pump. These pumps require ATPase activity and transfer calcium against the concentration gradient. The calcium ions are pumped outside of the cell and not cell inside.
Thus, the correct answer is option (b).
Answer:
Neurons
Explanation:
Neurons are the cells used in the nervous system
