Clean Air Act (CAA), US Federal law, passed in 1970 and later amended, to prevent air pollution and thereby protect the ozone layer and and promote public health. The clean air act gave the federal environmental protection agency the power it needed to take effective action to fight environmental pollution. Hope this helps シ
Answer:
A - DNA
B - mRNA
C - nuclear pore
D - tRNA
E - ribosome
F - rRNA
Explanation:
<em>The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.</em>
The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
