The correct answer is B. AUG
Explanation:
In biology, translation refers to a process that occurs in cells as proteins are synthesized, translation occurs after transcription and implies the de-codification of messenger RNA that contains genetic information to a polypeptide (chain of amino acids). This process occurs as codons in mRNA attach to anticodons, the first codon in this process is an AUG codon that is attached to Methionine amino acid. This occurs in most cells including prokaryotes and eukaryotes although and just in very rare cases the translation begins with a different codon. Thus, the codon that is most often recognized as the start codon for translation is AUG.
The major reason for bird species decline is loss of habitat, especially grasslands and forests. All have experienced declines in some areas since the 1960s and '70s, and further declines are anticipated, due to habitat loss and deforestation, and climate change
Polypeptide chains consist of long chains of amino acids. They are formed together by peptide bonds.
Answer:
Reticular formation
Explanation:
An ancient structural component of the human brain stem, Reticular formations (RFs) comprise several groups of nuclei distributed throughout the brain. In reference to structure, RFs are a net-like arrangement of multi-polar neurons, in a densely interwoven group of fibers. These don't have clearly defined borders, and extend from the midbrain to make up the brainstem's core.
Brainstem RFs are connected to the cerebral cortex and hypothalamus- it mediates sensory functions such as touch, vision and hearing. As these also continue into the hypothalamus, they play a role in arousing the body into wakefulness or an alert state.
