Answer:
The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its surrounding environment.
Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.
Mountain chains that are now separated by bodies of water on different continents would match up if these continents are placed next to each other, as they were when pangaea existed.
Answer:
Explanation:
During glycolisys in cytoplasm, first step involves adding two phosphates to glucose molecule. This step requires the use of two ATP molecules. The next step is splitting 6 carbons glucose into two 3 carbons pyruvates. This step produces 4 ATPs and 2 NADHs. However, since we used up two ATPs during the initial phosphorylation, the net gain is only 2 ATPs
The fluorescence marker tags to the enzyme when see with a powerful microscope the fluorescence will be observed in the mitochondrial matrix of the cell.
Explanation:
The enzyme responsible for the transfer of acetyl CoA group to oxaloacetate is ATP citrate lyase. It is produced in the matrix of the mitochondria in the cell during aerobic respiration.
The transfer of acetyl CoA group to oxaloacetate group marks start of the Kreb's cycle which also occurs in the matrix of mitochondria.
Hence the enzyme ATP citrate lyase when tagged with fluorescence will be seen in mitochondria of the cell.
