yarga [219]
Removal of introns and the splicing together of exons.

Introns are regions of the DNA code that do not code for amino acids; therefore, they need to be removed before the mRNA strand is translated. Exons are the parts of the strand that do code for proteins, so they need to be pieced together once the introns are removed.

When did Cyanobacteria start producing pure oxygen
Travka [436]

<u>Answer:</u>

Cyanobacteria start producing pure oxygen around 200 million years ago.

<u>Explanation:</u>

Many scientists believed that Earth did not have any oxygen. Cyanobacteria or the blue green algae are the microbes which produced oxygen for the first time with the help of photosynthesis.  This was around 4.5 billion years ago: after Hadean eon.

They were very simple, but they produced oxygen in the early earth’s atmosphere. So, they brought evolution on earth. This “blue-green algae” exists in salt water, rocks and soils and play a major role in maintaining the ecosystem.

Multiple sclerosis and atherosclerosis are similar in that they both refer to:
alukav5142 [94]

The conditions mentioned are both a type of sclerosis, which refers to the hardening of a certain anatomical feature.

In atherosclerosis, the affected <u>anatomical feature </u>is the artery. This is a condition that causes the <u>obstructions </u>of <u>blood flow </u>through the artery as a result of plaque buildup along the artery walls. Unlike with MS, atherosclerosis does not present symptoms until the obstructions are severe or the plaque loosens, which can lead to <em>heart attacks</em>, among other consequences.

In the case of Multiple Sclerosis, the affected anatomical structure is that of the nerve. This is a condition for unknown reasons, causes the <u>immune system </u>to attack the myelin covers of nerve cells which act to protect the cell. The absence of this cover causes the build-up of plaque along the nerve axon, <u>stiffening </u>and <u>disrupting </u>the communication of the nerves with the central nervous system.
