Since rifamycin inhibits the enzyme RNA polymerase, which is a key enzyme for synthesizing messenger RNA, the immediate effect of this antibiotic would be the inhibition of the process of transcription.
Messenger RNA is essential for protein synthesis because it is the mediator between the information in the DNA sequence and the process of translation in which the proteins are made. Therefore, by inhibiting RNA synthesis rifampicin ultimately stops the production of proteins.
Answer:
Please find what occurs in the single nucleotide-pair substitution below
Explanation:
Single nucleotide-pair substitution is a type of point mutation as stated in this question. Point mutation is when one nucleotide base (single) is affected in the sequence. In this single nucleotide-pair substitution, ONE nucleotide base is substituted by another base.
For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG. Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.
Ribosomes produce the proteins
Answer:
E. Variations in Earth's orbit occur gradually over 100,000 years.
A scientific hypothesis is an educated guess that is made about an observation based on the prior knowledge of the scientist. Hypothesis are always testable.
An hypothesis can be tested through experimentation and it can also be tested through deductive methods.
