Answer:

Base

Explanation:

A base is a substance which releases hydroxyl ion (OH-). Bases are also known as alkalis and physically they are soapy and bitter in taste. In litmus paper test, they give blue color. An acid on the other hand is a substance which releases a proton or Hydrogen ion (H+). Acid and base both react to form a salt and the process is known as neutralization reaction. We have a pH scale which has a range from 0 to 14. If a substance has a pH more than 7 then that means it is a base but if a substance has pH less than 7 then the substance is acid.

One of the examples of base is sodium hydroxide (NaOH) which dissociates into Na+ & OH- to release OH-.

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.
