Answer:
Your answer is C) Carbon Dioxide.
The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.
Answer:
The question is incomplete, it lacks the mRNA sequence. The sequence is as follows:
5′−AUGGCAAGAAAA−3′
The answer is Met-Ala-Arg-Lys
Explanation:
Gene expression in living organisms involves the process of transcription and translation. Transcription is the synthesis of a complementary strand of mRNA from a DNA template while translation involves using the transcibed mRNA as a template to synthesize amino acid sequence (proteins).
In the RIBOSOME, where the synthesis of protein occurs, the mRNA nuceleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. The collection of all codons is the genetic code. Hence, for a specific mRNA sequence that reads 5′−AUGGCAAGAAAA−3′. The nucleotides will be read three at a time starting with AUG which is a codon that encodes METHIONINE.
Next, GCA is a codon that encodes ALANINE
Next, AGA is a codon that encodes ARGININE
Finally, AAA is a codon that encodes LYSINE.
Hence, the amino acid sequence using the above mRNA sequence, will read: Met-Ala-Arg-Lys
B is correct. Krypton is a noble gas which has a full outer shell of 8 electrons and is generally unreactive because of it.
