In order to see an absorbance peak in an ir spectrum, the molecule must ___________.

1 answer:

4 0

<span>The answer is b. have a change in dipole moment

When a molecule absorbs an infrared ray, its energy will increase. The energy will increase the rotational movement or the molecule. If the energy increases further, it will become the vibrational movement. Dipole moment will be increased if the vibrational movement is increased.</span>

What is mitochondrial genomes?

The DNA found in mitochondria, which are cellular organelles found in eukaryotic cells that transform chemical energy from food into a form that cells can utilise, such as adenosine triphosphate, is known as mitochondrial DNA (mtDNA or mDNA)](ATP). Only a small amount of the DNA in a eukaryotic cell is contained in the mitochondria; the majority of the DNA is found in the cell nucleus and, in plants and algae, also in plastids like chloroplasts.

The first large portion of the human genome to be sequenced was mitochondrial DNA.

According to this sequencing, the human mtDNA contains 16,569 base pairs and codes for 13 proteins.

Animal mtDNA serves as a cornerstone of phylogenetics and evolutionary biology because it evolves more quickly than nuclear genetic markers .
