Answer:
Every amino acid in the chain changes, making the protein not functional
Explanation:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
RNA plays central role in the pathway from DNA to proteins.
I believe it's "pollen".
When the pollen grains are washed down into lakes/rivers, scientists can take a sample of the sediment layers and see what plants were growing at that time. They can then make inferences about the climate and how that affected the plants growing there.
Hope this helps!
Answer:
Their similarity
Explanation:
Pharyngeal pouches are structures in vertebrates that develop in different parts of the body mainly in the face or neck. The similarity in their position and structural indicates a similarity . These structures provide evidence of evolution that the organisms evolved from the same ancestry.
