Answer:
The acronym mRNA means messenger ribonucleic acid, the nucleic acid responsible for transporting genetic information to the ribosome so that protein synthesis can occur.
Explanation:
Messenger ribonucleic acid or mRNA, is a nucleic acid responsible for containing the genetic code, organizing it into codons —depending on the specific sequence of nitrogenous bases— and taking it to the ribosome for translation and initiation of protein synthesis.
A codon is a sequence of three mRNA nucleotides, each of which encodes a specific amino acid, in addition to:
- <em>Marking the start of protein synthesis, by means of the UAC start codon, which also encodes for amino acid methionine (MET).
</em>
- <em>Indicate the stop of protein synthesis, by means of the STOP codons </em>—<em>UAA, UAG and UGA</em>— <em>which do not code for amino acids.
</em>
This can be seen in the table:
- The first line is the sequence of nitrogenous bases of one of the DNA strands.
- The second line should indicate the sequence of complementary bases of the other DNA strand, which will be transcribed. However, the presence of uracil indicates that it is the mRNA transcribed
- The third line is the sequence of nitrogenous bases in the mRNA strand, organized in triplets or codons.
- The fourth line expresses each of the amino acids and instructions found in the mRNA fragment that was transcribed methionine (start), lysine, tryptophan, proline and STOP (although GUU encodes the amino acid valine and is not a STOP codon).
True. If they are potentially infectious then they need to be disposed of so others will not be contaminated!
The most abundant type of pollution in national parks at that time was air pollution and it had begun to reduce biodiversity as organisms were leaving polluted areas for cleaner ones, or they simply were not able to survive.
Answer: Living organisms need to maintain homeostasis constantly in order to properly grow, work, and survive. In general, homeostasis is essential for normal cell function, and overall balance. For this process to function properly, homeostasis helps our body to keep both water and salt at a balance level.
