B is the right answer. Plants use light in photosynthesis to make food, and cellular respiration to break them down.
Appalachian Mountains are a part of the Lithosphere
Answer:
D. functional tRNAs have been spliced by splicesomes.
Explanation:
Functional tRNAs are not spliced by splicesomes, they are trimmed with the help of RNAases instead.
In all tRNAs, RNAase P cuts at 5'end so as to produce a monophosphate because a phosphodiester bond consists of only one phosphate and 2 sugar molecules.
After that 3'end processing occurs in which RNAase II and RNAase D remove extra nucleotide sequences at 3' end. CCA is added at 3' end later on with the help of enzyme named as tRNA nucleotidyltransferase.
So, there is no role of splicesomes only RNAases and other enzymes are involved in tRNA processing.
Glia cells have more activity and are more essential than previously thought. To start they help with Neuronal communication, they help to potentiates the communication between the neurons, also it potentiates the cerebral functions, lastly, these cells migrate to regions of the brain where pathologies are found and proliferate, interacting with the immunological system.
