Species with more likely homologous structures share a common ancestor.
- D. share a common ancestor.
<h3>What are example homologous structures?</h3>
The most correct definition for homology would be: They are structures of individuals, of different species or not, that were inherited from a common ancestor. The human arm is homologous to the horse's front leg. The bat's wing is homologous to the whale fin.
With this information, we can conclude that homologous have same embryological origin of structures from different organisms, and these structures may or may not have the same function

Answer:
WHO is involved: (major protein players)
WHAT is being completed:
WHEN does it occur in the cycle of the cell:
WHERE does it occur in prokaryotes or eukaryotes:
WHY does replication happen:
Explanation:
These are the 5 W's for any situation in life but directly applied to biology and DNA these are the exact and specific W's
Answer:
transcription of mRNA from DNA
small ribosomal subunit binds to mRNA
initiation complex formed with addition of large ribosomal subunit
translocation
codon recognition (non-initiating site)
peptide bond formation
ribosome reads a stop codon
polypeptide chain is released from the P site
ribosomal subunits dissociate
Explanation:
The above describes the process of translation in the ribosome. After transcription of DNA to mRNA, the mRNA is taken to the ribosome to undergo translation, here the mRNA binds to the small ribosomal subuits and to other initiation factors; binding at the mRNA binding site on the small ribosomal subunit then the Large ribosomal subunits joins in.
Translation begins (codon recognition; initiating site) at the initiation codon AUG on the mRNA with the tRNA bringing its amino acid (methionine in eukaryotes and formyl methionine in prokaryotes) forming complementary base pair between its anticodon and mRNA's AUG start codon. Then translocation occurs with the ribosome moving one codon over on the mRNA thus moving the start codon tRNA from the A site to the P site, then codon recognition occurs (non-initiating site again) which includes incoming tRNA with an anticodon that is complementary to the codon exposed in the A site binds to the mRNA.
Then peptide bond formation occurs between the amino acid carried by the tRNA in the p site and the A site. When the ribosome reads a stop codon, the process stops and the polypeptide chain produced is released and the ribosomal subunits dissociates.
I believe the answer is cell theory
