The endoplasmic reticulum aids in the production and movement of proteins and other materials through the cell.
An unknown mtDNA sample sample is matched to a sample of mtDNA that was found at the crime scene.<span> This is how mitochondrial DNA (mtDNA) typing is used in forensic science.</span>
<span>Unlike nuclear DNA typing, mtDNA isolation is quite easy because its number is quite large. mtDNA copies rang from 100 to 10,000 per cell. It is also more stable and stronger than the nuclear DNA; that is why even unsolved cases from years ago use mtDNA typing as reference for possible conclusion.</span>
The use of mRNA and reverse transcriptase is part of a strategy to solve the problem of post-transcriptional processing. RNA is synthesized in the process of transcription and then transferred to the cell cytoplasm where it is translated into protein. Post transcriptional modification or processing is a process where the primary transcript RNA is converted into mature RNA.
Answer and Explanation:
This is a model of an atom. Atoms are made up of three main parts: neutrons, protons, and electrons.
Neutrons are neutrally-charged subatomic particles, protons are positively-charged subatomic particles, and electrons are negatively-charged. Neutrons and protons are always located in the nucleus of the atom, which is basically the central location. Electrons, on the other hand, orbit all around this nucleus.
In the model, the protons and neutrons should be labelled in the center big golden ball, while the electron should be labelled on the small spheres "orbiting" this big center one. The electrons should also be labelled "negatively charged". Finally, the nucleus is positively charged because it's made up of protons (which are positive) and neutrons (which have no charge).
