Only 22 tRNAs are required for mitochondrial protein synthesis. The normal codon–anticodon pairing rules are relaxed in mitochondria, so that many tRNA molecules recognize any one of the four nucleotides in the third (wobble) position, allowing four codons to be recognized by a single tRNA.

Density-independent factors limit population size regardless of the population’s density.

Common density-independent factors include natural disasters such as tornadoes, hurricanes, floods, and fires.
