DNA it is a string of dna which can be prooved anytime or you can call it DNA replication
Answer:
Salmon populations in the United States is declining due to the following factors:
1. Over-fishing and human activities have put a major influence on the population of salmon.
2. Due to industrialization, urban growth, unplanned farming, deforestation, and pollution would have imparted strains on the stocks of salmon. Apart from this chemical contamination from the industrial run-off and agricultural activities are also declining populations of salmon.
3. Genetically modified fish from hatcheries usually escape and interbreed with wild fish, thus, changing the genetic features of the populations.
4. Construction of hydropower dams is also a major cause of the salmon population declining.

Answer:
The correct answer is - Methionine, serine, histidine, aspartate, glycine
Explanation:
The new segment of DNA is: 3'-TACAGGGTGCTACCCACT-5', which performs two processes to form a peptide chain, transcription, and translation. In transcription, the DNA segment is encoded to an mRNA molecule which has its complementary sequence to DNA sequence.
New DNA strand: 3'-TACAGGGTGCTACCCACT-5'
mRNA sequence: 3'-AUGUCCCACGAUGGGUGA-5'
The translation of this mRNA would be on the basis of chart
AUG - Methionine (start codon)
UCC - serine
CAC - histidine
GAU - aspartate
GGG - glycine
UGA - stop codon
The peptide chain would be - Methionine, serine, histidine, aspartate, glycine
