Answer:
<h2>Ribozymes</h2>
Explanation:
Ribozymes is a ribonucleic acid (RNA) enzyme, which is made up only by RNA.
RNA self-splicing is discovered by T. Cech (1982).
They plays very important role in protein synthesis as , they are part of ribosomes. Ribozymes also plays very important role in RNA splicing in gene expression.
RNase P.
Example:
Peptidyl transferase 23S rRNA.
Leadzyme.
Group I and II introns , and there many other ribozymes.
Answer:
Valinomycin is an antibiotic that are mainly used against the bacteria streptomycin. The valinomycin might also acts as the ionophore used for the regulation of the ions transport.
Only some selected particles can pass down to the plasma membrane. The hydrophobic molecule can easily cross the plasma membrane. Valinomycin is hydrophobic on its exterior surface and easily diffuse through the cell membrane. Valinomycin is hydrophillic from the interior surface and used for the encapsulation of the polar ions.
Skeletal muscle contractions do in fact demand large quantities of ATP (adenosine triphosphate), the universal source of cellular energy. In order to accommodate this necessity, skeletal muscle cells (myocytes) are packed with mitochondria, which are the energy powerhouses of the cell.
However, the production of ATP would halt in mitochondria if the necessary substrates (fuels) are not present to enter these organelles, mainly glucose and oxygen (O2). So, additionally, skeletal muscle is also loaded with glycogen, a storage form for glucose (as starch), and myoglobin, an enzyme similar to hemoglobin in that it binds an O2 to hold it for use during contraction.
Answer:
Its DNA
Explanation:
Each RNA nucleotide consists of three parts: a sugar, a phosphate group, and a nitrogen-containing base. The four RNA bases are adenine, uracil, guanine, and cytosine—often referred to as A, U, G, and C. RNA shares three bases in common with DNA: adenine, guanine, and cytosine. Instead of uracil, DNA contains thymine.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
Answer:
The limbic system is a system of structures that includes the amygdala. This system has been implicated in emotion behavior.
