An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
A duplication is a mutation where the chromosome carries repetitive sets for a gene.
The process of __clonal selection__
In the model, a codon is identified as part of the mRNA strand. A codon is a series of three nucleotides on mRNA that codes for an amino acid.
mRNA
This is one form of RNA that serves as a template for protein synthesis. It is transcribed from DNA and then translated at ribosomes to produce a protein.
It only allows certain things through, such as water. One way to remember it is to think about how you wouldn’t eat just anything, and the cell doesn’t let just anything in. I hope this helps
