Answer: I think number 2 b
Explanation:
Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
<em>Codons: AUG-GUG-CAU-GUC</em>
<em>Amino acids: Met - Val - His - Val</em>
<em>Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.</em>
The incorrect among the choices is "<span>direct signaling involves the activation of g proteins"
This is incorrect because direct signaling does not involve the activation of g proteins rather it involves the activation of ion channels resulting to either an excitation reaction (depolarization of the membrane) or an inhibition reaction (hyperpolarization of the membrane); and this will ultimately affect the action of the organ the nerve is innervating.</span>
Answer:
Oh gosh, thank you! (I feel like this'll get deleted, so here are the answers: Tony Stark became Iron man when he was in like this military place? I don't know the exact details, but when people were trying to fight him he made a suit to fight back. The suit was surprisingly powerful, so he re-made it to be more appealing, light-weight, and stronger.
All he has to do is change into his suit. He doesn't actually have any superpowers, unless you consider being really smart a super power)
