<span>An electric current is running through the gel in the electrophoresis with positive pole on the bottom. So, only negatively charged particles can migrate through the gel in the electrophoresis. </span>Since DNA is negatively charged, it migrates toward the positive pole of the gel. This characteristic enables DNA to move through the gel.
Answer:
The overall strategy employed in the catabolism of the carbon skeletons of the 20 amino acids is conversion to citric acid intermediates such as acetyl-CoA
Explanation:
The breakdown of the different carbon skeletons of the 20 amino acids is strategically channelled towards the citric acid cycle. Six major products are obtained in the catabolism of the carbon chain of amino acids and these products all enter the citrc acid cycle. The six major products are acetyl-CoA, α-ketoglutarate, succinyl-CoA, fumarate, oxaloacetate and pyruvate.
The amino acids that are broken down completely into acetoacetyl-CoA and/or acetyl-CoA are said to be ketogenic since they yield ketone bodies in the liver.
The amino acids that are broken down into α-ketoglutarate, succinyl-CoA, fumarate, oxaloacetate and pyruvate can be converted to glucose and glycogen and are said to be glucogenic. Pyruvate can further be converted to either acetyl-CoA or oxaloacetate. Some amino acids though are both ketogenic and glucogenic, e.g. tryptophan, threonine.
Answer -
1. <span>Convergent continental-continental boundary.
2. Convergent oceanic-oceanic boundary.
3. Convergent oceanic-continental boundary.
(Confidently Correct)
Reason -
Each different reasoning for
1.Its continental boundary is because its crashing into each other like a collision forming the Himalayas.
2.The lithosphere is pushing down where as the other side is acting on it making it go and move down.
3. This type of oceanic and oceanic boundary is one place is moving upward where as the other one is moving down.

C, a collection of photosynthetic protons arranged in a thylakoid membrane.
According to the way you defined the image, the right answer is C. Amino Acid.
The amino acids found in proteins all have the same basic structure: they are oriented around a central carbon atom, the α-carbon, on which the carboxyl group (-COOH) is articulated, the amino group (-NH2). ), a hydrogen atom (-H) and a lateral group (denoted -R). It is the nature of this lateral group (also called side chain) which differentiates the amino acids between them.
The central α-carbon is therefore asymmetrical in all cases except that of glycine (because glycine has a hydrogen instead of a side chain). This means that it is possible to have two different conformations of the same amino acid conformations that can not be interconverted without breaking and reassembling covalent bonds. These conformations L and D are designated. Although both can be synthesized in the same chemical reaction, only the L-form is used in the proteins.
