Natural selection means that the organisms better adapted to their environment, that is, they have developed the right characteristics/skills/response to the external ambient, have higher chance to survive, making the next generations genetically inherit such acquired surviving characteristics.
These generations will thus have a higher chance of survival, making these species being "naturally selected" as survivors, while those who haven't or are slower in this process, have a higher risk of elimination.
Answer: d). UAG
Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.
From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.
MRNA is responsible for carrying coded information from the nucleus.... i hope you it will help you.... :)
