Answer:
refers to the ability to distinguish fine structure and detail in a specimen
Explanation:
Resolution can be defined as the capacity of a microscope to distinguish detail. Resolution can be measured as the minimum distance between two distinct objects of a specimen which can still be observed as separate entities. Some important factors influencing microscope resolution include 1- objective numerical aperture, which is related to the angles of light that are collected by a lens (can be improved by using immersion oil), 2- degree of aberration correction, 3-magnification (i.e., degree of visual enlargement of an observed object), 4- contrast methodology, etc. In a light microscope, for example, the maximum resolution that can be reached is 200 nanometers (nm), being this limited by the wavelength of light waves due to diffraction, while the maximum magnification is generally x1500.
Answer:
mRNA
Explanation:
Messenger RNA (mRNA) is a single-strand RNA derived from the process of transcription, in which one strand of DNA serves as template to synthesize this molecule. The mRNA has an identical sequence to the gene, with the exception of thymine nucleotides that are replaced by uracils. During this process, the RNA polymerase synthesizes a precursor mRNA molecule (pre-mRNA), which contains both intronic and exonic regions. Subsequently, the introns are eliminated by RNA processing enzymes in a process known as RNA splicing, thereby resulting in a mature mRNA. Finally, this mature mRNA is decoded by the ribosome during the synthesis of proteins in a process named translation. The translation involves another type of RNA molecule: the transfer RNAs (tRNAs), which recognize codons in the mRNA and act as adaptors by the incorporation of specific amino acids in the protein sequence.
An enzyme called helicase breaks the bond between nitrogeneous base, where the two strand of DNA split.
The speed is called 'average kinetic velocity' and this velocity is further distribued by the Maxwell Boltzman speed distribution
