Early geneticists wondered how only four nucleotides can specify the sequence of 20 amino acids in proteins. They hypothesized t

hat there must be a code that linked the nucleotide sequence in a gene to the amino acid sequence in a protein. Each nucleotide code is called a codon. Today we know that there is a genetic code in which __________nucleotide(s) code(s) for each amino acid.

Leokris [45]

Answer :There was enough oxygen in the atmosphere to support a major burst of life on Earth

Explanation:

The Great Oxygen Event marks the time, approximately 2.5 billion years ago, when there was enough oxygen in the atmosphere to support a major burst of life on Earth

For the first half of the Earht's history, there was no oxygen in the atmosphere. It was inhabited only by single-celled organisms.Of  those simple life forms, the cyanobacteria may have. evolved a way to take energy from sunlight, and used it to make sugars out of water and carbon dioxide. They used the same chemical process we know as photosynthesis. This released vast quantities of oxygen into the atmosphere and  triggered the evolution of complex life.
