∙ 14y agoThe active site exists as a natural consequence of the shape of the rest of the protein. Essentially, the peptide residues in the active site are held in position by the intramolecular forces that give the protein as a whole its conformation.

∙ 14y agoThe DNA sequence is closest to the pig example on the worksheet. The amino acids Gly, Thr, Leu, and Ala are from the "unknown animal." On the worksheet, the pigs amino acids are Gly, Thr, Phe, and Ala. There is only one different amino acid between the two. I'm not sure of the exact animal but I'm guessing its close to a warthog since it was found in the forest. Other websites have said that it's close to a gorilla, but I think this is incorrect due to the fact that most of the amino acids made from the DNA sequence of the chimpanzee and a human don't match up with most of the ones on the "unknown specimen."
rRNA is a massive molecule consisting of two parts; a small section, and a large section. It is between these two sections that the mRNA fits, and into the large selection that the tRNA complexes (with attached amino acids) are taken. rRNA molecules have two main binding sites. When a tRNA molecule is bound, the mRNA molecule moves along one space, and another tRNA molecule binds. When this happens, the amino acids at the ends of the tRNA molecules are very close together, and a peptide bond forms. The mRNA then moves along again and the first tRNA molecule breaks away.

They wouldn't stick together naturally.

Transcription: In the nucleus, DNA is unzipped by DNA helicase. This DNA is then copied by DNA polymerase III to form a new copy of RNA. The RNA will then leave the nucleus via a nuclear pore and enter the cytoplasm. Translation: In the cytoplasm, The RNA (which contains A,U,C,G not A.C,T,G like DNA) will bind to a ribosome. Only 2 ribosomes are able to bind to the RNA at any given time. tRNA molecules in the cytoplasm will bind to the complementary bases of the RNA. The tRNA molecules are a triplet codon which recognises a 3 base sequence on the RNA*. This tRNA molecule is also attached to an amino acid, e.g AUG is methionine. As the 2 ribosomes move down the length of the RNA strand 2 tRNA anticodons will be brought in close proximity and so a peptide bond will form between the 2 amino acids attached to them. The ribosomes will move along the entire length of the RNA and a polypeptide is synthesised. The polypeptide can then be cleaved in several different places to make several different proteins. This is how one length of DNA can code for many different proteins. *a triplet codon is used as this enables the full 20 amino acids to be coded for. If one base coded for one amino acid there could only eb 4 possible amino acids. If 2 bases coded for an amino acid then there still not be enough possible codes. However when 3 bases are used there are more possible codes than amino acids, this is why one amino acid can have several different base sequence codes.
Amino acids are not part of evolutionary theory. Evolution is the change in allele frequency over time in a population of organisms. The theory of evolution by natural selection explains much of the mechanism for evolution. Alleles are different molecular forms of the same gene. This means different alleles could code for the manufacturing of different proteins, or proteins with different functions. Proteins are made of amino acids, which is as close as amino acids get to the theory of evolution. If it were some other molecule then the theory of evolution would still be explaining much the same thing.

Enzymes and substrates will bind together to catalyse chemical reactions. The spot on the enzyme where the substrate will bind is called the active site of the enzyme. The enzyme and the substrate are usually a pretty close fit, hence the naming of the induced fit model.

yes they are very close together
It means your eyes are very close together.

Take the protein cytochrome C. There is not one amino acid difference in structure between we humans and our close relatives, the chimpanzees. There are 51 differences between humans and single celled yeast in amino acids. We can strongly and simply infer from this data the evolutionary relationship among the three species mentioned here.
The active site of an enzyme is the specific region where the substrate molecule(s) bind and undergo a chemical reaction. It is typically a small and highly specific pocket or groove that accommodates the substrate molecule(s) and facilitates the catalysis of the reaction by lowering the activation energy. The active site is formed by amino acid residues and often contains key functional groups that participate in the enzymatic reaction.
