Hi there!
Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins.
<span>In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.</span>
Why am I slightly threatened by this?
TOPOISOMERASE
There are various function of DNA toposisomerase such as:
1.accessing DNA- this happens during transcription and replication, DNA must be unwound for this to happen, Topoisomerase I make a single break to create an access.
2. Removing DNA super coils- Topoisomerase prevents DNA to be supercoiled, this happens during transcription of DNA to RNA
3. Strand breakage- It can introduce single strand breaks that are required for DNA to be exchanged to adjacent chromosomes.
If total food calories exceed daily energy expenditure, excess calories accumulate as <u>fat in adipose tissue</u>
Explanation:
Calories is the measurement of energy released when the food is digested.
Proteins, carbohydrates and fats get digested to release energy.
Proteins and carbohydrates yield approximately equal amount of energy on getting digested. While fats yield maximum amount of energy.
If the amount calories produced by digestion of food exceeds the total amount of calories used up then the excess calories are stored as fats in the adipose tissue of the body.
This is the major reason why overeating and decreased physical activities results in obesity.
