Atlantic cod is a special type of marine fish from the family Gadidae. It is a commercially important fish because it is consumed by humans. The Atlantic cod lives in the cold waters and in the deep seas throughout North Atlantic. The Pacific cod on the other side lives in the northern Pacific.
Answer:
Genetic modification decreases the genetic variation of the modified organism
Explanation:
Barbiturates are drugs that act as depressants on the central nervous system. They have a wide effect range, which means, the drugs can cause mild to total anesthesia effects. If the effectiveness of a barbiturate as a sedative depends on its ability to penetrate the non polar membrane of the cell, then based on this fact, hexethal will be more effective. This is because, it is more non polar than barbital; hexetal has a helxyl gruoup instead of the ethyl group present in the barbital.
Answer:
The amino acid sequence resulting from the DNA code TACGGGGCGATTGG is Methionine (starting codon), proline, arginine and STOP codon.
Explanation:
DNA is the molecule that contains four nitrogenous bases in its structure, whose sequence determines the order and amount of amino acids that a protein will have.
For protein synthesis to occur, DNA must be transcribed into mRNA, which leaves the cell nucleus for translation to occur in the ribosomes. The sequence of nitrogenous bases of the mRNA is organized into triplets or codons, which determine:
- <em>Initiation of protein synthesis.
</em>
- <em>Sequence and number of amino acids that a protein contains.
</em>
- <em>End or stop of protein synthesis.
</em>
For the given DNA sequence, the corresponding amino acids are:
- DNA TACGGGGCGATTGG
- mRNA AUGCCCCGCUAACC
- Codons AUG-CCC-CGC-UAA-CC
- Amino acids Met - Pro - Arg - STOP
The last two cytosine molecules are not translated because they do not form a codon and because the previous codon completed protein synthesis.
