Answer:
Met-Ser-Ser-Leu-Ser-Leu
Explanation:
mRNA have triplet codons and each triplet codon codes for an amino acid. An amino acid can be coded by many triplet codons but one amino acid can only code for a single amino acid.
AUG is a start codon that codes for initiator amino acid called methionine. Serine can be coded by UCU, UCC, UCA, UGC, AGU, AGC triplet codon. leucine can be coded by UUA, UUG, CUU, CUC, CUA, CUG.
So the codon sequence 5' AUG-UCU-UCG-UUA-UCC-UUG 3' will generate Met-Ser-Ser-Leu-Ser-Leu amino acid sequence.
Answer:
A.
Explanation:
Lac Operon is defined as an operon that is used by E.coli for transporting and metabolizing lactose.
Allolactose is a disaccharide like lactose, that binds to lac repressor and restrict its binding with DNA. It triggers expression of a operon or gene.
So, adding allolactose to the bacterial growth media, block the activity of lac repressor and trigger the activity of bacteria to metabolize the sugar lactose.
Hence, the correct answer is "A."
