What does the sympathetic and parasympathetic do ?
svetlana [45]

The sympathetic and parasympathetic are responsible for the body's spontaneous actions, such as breathing, heartbeat, digestion, body temperature control.

<h3>What is the function of the sympathetic and parasympathetic nervous systems?</h3>

The sympathetic nervous system acts in an opposite way to the parasympathetic one, preparing the organism to react in situations of fear, stress and excitement, adapting the functioning of several internal systems to a high state of readiness.

In this case, the Sympathetic nervous system also controls body functions that are rarely conscious and parasympathetic nervous system the part of the autonomic nervous system responsible for stimulating actions that allow the body to respond to calm.

Which of the following mRNA sequences could code for the polypeptide met-arg-ser-leu-glu?
vampirchik [111]

Answer:

5'-AUGCGUAGCUUGGAGUGA-3'  

Explanation:

(a) Break the string into triplets.

5'-AUG-CGU-AGC-UUG-GAG-UGA-3'

The string contains six codons.

The initiation codon is AUG (Met)

That eliminates Options 1 and 4.

(b) Identify the stop codon

There are six codons, so the sixth is the stop codon, which must be UAA, UGA, or UAG .

That eliminates Option 2, which ends with UGG.

The correct answer must be Option 3.

(c) Check

Translate the codon string.

5'-AUG-CGU-AGC-UUG-GAG-UGA-3

    met   arg    ser    leu    glu    stop

That's the correct sequence.
