1. The correct answer is: a. There are more mRNA bases than amino acids.
The transcription of monocistronic mRNA in prokaryotes is a rare process (it is more characteristic for the eukaryotes). Monocistronic mRNA is RNA, which encodes for only one or specific protein. Three bases of mRNA encode one amino acid of protein, thus it has more bases than amino acids of the final product, protein.
2. The correct statements are:
The mRNA contains 5' and 3' untranslated regions.
The stop codon does not code for an amino acid.
The start site of transcription is upstream of the start codon.
Each codon contains 3 RNA bases.
All of these approve that more bases are in mRNA since not all of them are translated into amin oacids.
Other statements are hallmarks of eukaryotic RNA processing, and therefore not relevant to prokaryotes.

<span>The answer is A……A. Salamanders have a
larvae stage that breaths through gills while the adults breaths through lungs.
The larvae stage develops 30 days after
hatching and may metamorphose into an adult (60 days from hatching) ore remain as
larvae to maturity. </span>
1. The enzyme glycogen phosphorylase removes terminal glucose residues from glycogen by cleavinα(1,4) linkages.
2. Enzyme activity stops when the enzyme reaches a point four glucose residues from a branch point, which is an α(1,6) linkage
3. The transferase activity of the debranching enzymes moves three glucose residues to another branch, connecting them by an α(1,4) linkage
4. The <u>glucosidase</u> activity of the debranching enzyme removes the glucose at its<u> α(1,6) li</u>nkage
5. The enzyme <u>glycogen phosphorylase</u> continues removing terminal glucose residue
Explanation:
Several enzymes are required for the breakdown of a glycogen molecule to a glucose-6-phosphate molecule through glycogenolysis. These enzymes are completely responsible for degrading the glycogen, remodeling the glycogen and converting the glycogen. This is a regulatory process which takes place where is glucose lack or to accelerate fluid. The main enzymes that take part in this glycogen pathway are glycogen phosphorylase and the degrading enzyme.
