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.

Softa [21]

Answer:

The animal cell will take in water until it eventually swells or burst

Explanation:

Osmosis is an important phenomenon that drives the movement of water across membranes. It is defined as the movement of water molecules from a region of high water concentration/low solute concentration to a region of low water concentration/high solute concentration across a semi-permeable membrane.

In this case, the animal cell with a molar concentration of 2.0M is placed in 0.0M and 1.0M sucrose solutions. This means that the cell is placed in an hypotonic solution (solution with low solute concentration), hence, water will move from the extracellular solution into the animal cell since the solute concentration in the cell is more. The animal cell will begin to swell and eventually burst.

Archaea differ from bacteria in that archaea
o-na [289]

Answer:

The correct answer is A) Have diverse cell wall compositions

Explanation:

Both bacteria and archaea comes under prokaryotes because they both lack a membrane-bound nucleus. The difference between archaea and bacteria is in their cell wall composition.

The bacterial cell wall is made up of peptidoglycan and the archeal cell wall is made up of pseudo-peptidoglycan. In bacteria, peptidoglycan contains N acetyl muramic acid and N acetyl glucosamine unit but in archaea, the N acetyl muramic unit is replaced by some other unit and the linkage of two units is also different in archaea. So the right answer is A.
