Which of the following mRNA sequences could code for the polypeptide met-arg-ser-leu-glu?
5' ATGGAGGTTCGATGCGTA 3'
5' AUGAGUAGCUUCGAGUGG 3'
5' AUGCGUAGCUUGGAGUGA 3'
5' AUGCUAAAUGUGCGAUGA 3'

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.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
