If the sequence of bases on the mrna codon is auu what would be the sequence of bases on the trna anticodon
Klio2033 [76]

Answer:

uaa

Explanation:

An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.

Many species of gulls feed their chicks by regurgitating food. When parents return from foraging, the gull chicks peck at a red
makvit [3.9K]

Answer:

fixed action pattern, key stimulus; key stimulus, fixed action pattern

Explanation:

  • An innate behavior which specific to a species and is highly stereotyped is termed as a fixed action pattern.
  • This behavior occurs due to a neuronal network that is hard-wired in the species and the response is said to be generated following a key stimulus.
  • A key stimulus is the one that generates a fixed action pattern and this is also called a releaser.
  • A key stimulus can be in the form of shape, sound, color, or a combination of these.
  • In this case, the red spot is a stimulus for the chicks which causes them to peck at their parent's bill, and hence, the red spot is a key stimulus, and pecking of the chicks is a fixed action pattern.
  • The parents regurgitate the food only when the chicks peck at their bills, so pecking is a key stimulus for the parents which causes them to regurgitate the food which is a fixed action pattern.

Suppose we discovered a form of life like our own which utilized 20 amino acids, but had 6 nitrogeneous bases instead of the 4 o
mezya [45]
The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.
