Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. <span>5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs. </span>
Answer:
A parasitic relationship is one in which one organism, the parasite, live off of another organism, the host, harming it.
Answer:
B -the absence of the inducer, but not in its presence
Explanation:
In positive repressible regulalor mechanisms transcription of the structural gene(s) occurs in the absence of the inducer because proteins are normally bound to the pertinent DNA segment. when an inhibitor is bound by the inducer, it is prevented from binding the DNA. which will the stops the activation and transcription of the structural genes.
Example of positive repressible regulator is Activator .
Regulating the rate of transcription is a mechanism of gene regulation leading to the productionn of more than one protein product from a single gene.
