Answer:
True
Explanation:
Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
I not really sure what the answer is
Answer: start codon AUG of mRNA
Explanation:
The ribosomal assembly consist of two receptor sites, the P and A sites. The P site carries the peptidyl-tRNA, the growing peptide chain while the A site carries the new incoming tRNA with the amino acid to be added next.
The mRNA signal the initiation process with it start codon AUG. Because the start codon AUG codes for the amino acid methionine. A tRNA attach to methionine (tRNA-Met) binds to the start codon. The anti-codon UAC of the met-tRNA is correctly base pairing with the AUG codon on mRNA.
