Interpretation Introduction

(a)

Interpretation:

The reason by which cell C can grow in the HAT medium is to be determined.

Concept introduction:

HAT medium is the selection medium, used for mammalian cell culture. It is the combination of hypoxanthine, aminopterin, and thymidine. Hypoxanthine and thymidine are the intermediates formed in the DNA synthesis. While aminopterin is the inhibitor of dihydrofolate reductase.

Interpretation Introduction

(b)

Interpretation:

Distinction between the normal cells A and the cells that have taken up the foreign DNA is to be determined.

Concept introduction:

HAT medium is the selection medium, used for mammalian cell culture. It is the combination of hypoxanthine, aminopterin, and thymidine. Hypoxanthine and thymidine are the intermediates formed in the DNA synthesis. While aminopterin is the inhibitor of dihydrofolate reductase.

Biochemistry What is the process of "transamination" in either the muscles or the liver, that involves keto acid or glutamic acid? Please explain how the steps work. Thank you!
Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
