The average size of a human being is 1.7 meters for males and 1.6 meters for females.

Paramecium are members of the protozoa genus, among the largest unicellular algae. Its average size is among 50 to 330 micrometers.

White Blood Cell are up to 17 micrometers in diameter.

Escherichia coli is a type of bacteria, as a prokaryotic organism is much more smaller than a eukaryotic cell such asa the white blood cell. Escherichia coli is up to 2 micrometers in diameter.

Chickenpox virus are among the largest viruses, they are from 150 to 200 nanometers in diameter.

Ribosomes vary on size depending if they are Prokaryotic or Eukaryotic, where the first are up to 20 nanometers and the second are up to 30 nanometers.

Prion fibrils are aggregates comprised of several protein units. It size varies depending on the number of proteins, but the ones containing around 200 units can reach up to 27 nanometers.

Water molecule is comprised of two atoms of oxygen and one atom of hydrogen, its size is measured with picometers (1 picometer is equal to 1000 nanometers). A water molecule has a size of 275 picometers.

Frameshift mutations ____________.
castortr0y [4]

Answer:

The correct answer is option b. "cause a change in the reading frame of mRNA codons".

Explanation:

Frameshift mutations are among the most drastic mutations because in most cases, result in the translation of a completely different protein. Frameshift mutations are the result of insertions or deletion of one or more nucleotides, resulting in a change in the reading frame of mRNA codons. In consequence, the ribosome translates a different amino acid sequence, based on the new reading frame of mRNA codons.
