Primary consumers are the ones eating the plants, so mostly they are herbivores, compared to the secondary consumers, which eat both, that can be called omnivores
DNA fingerprinting is where DNA is used to create a profile for someone often in crimes. The STR or Short Tandem Repeats are used for this. STRs are non-coding sections of DNA which repeat themselves for example CACACACACACACACACACA the location of this STR and the length of the STR (how many times it repeats) are used to identify a specific person
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.
Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.
The answer would be -- A. Cenozoic
