A DNA sequence that is 15 nucleotides long would normally give rise to a polypeptide sequence that would be 5 amino acids long. This is assuming that all the nucleotides in the DNA sequences are strictly coded to form only sense codons and not a single nonsense codon, also called termination codon
A sense codon is a set of three nucleotides also called a triplet, that codes for a particular amino acid. A DNA sequence of 15 nucleotides has 5 codons.
A nonsense or termination codon is one that does not code for any amino acid. There are three nonsense codons found on mRNA, and these are UAA, UAG and UGA. So if the DNA sequence has one of these, then the amino acids in the polypeptide chain will be 4 in number
Answer:
The correct answer is ''carbon dioxide, water vapor and nitrogen.''
Explanation:
About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.
Answer:
The options
A. a random series of disconnected happenings.
B. Life is a circle.
C. a purpose and a final destination. D. that we are heading down the wrong path.
E. The golden age will come at last.
The CORRECT ANSWER IS C.
C. a purpose and a final destination
Explanation:
The western version of the myth of life as a journey implies A PURPOSE AND A FINAL DESTINATION.
The western myth of life as a journey implies that there is a start of an event or action and an end of that event or action too with intention or meaning. We are just along for the ride, we can not predict where our final destination will be or lead us to but our destiny will control the event and outcome.
