Question

In a mRNA sequence of Nitrogen base is 5' AUG GUG CUC AAA 3’. What is the correct sequence of anticodons which recognizes codons of mRNA?

a) UUU
b) GAG
c) UAC
d)CAC

Answer 1

Hint: mRNA is converted to protein during translation. A sequence of three nucleotides in mRNA encodes a specific amino acid and is referred to as a codon. Each mRNA correlates to a specific amino acid sequence that shapes the resulting protein. The beginning and end of translation are signaled by two codons, called start and stop codons.

Complete answer:
A nucleic acid is a linear nucleotide polymer that forms an integral part of the information transfer system in cells. Nucleotides consist of a nitrogenous base, a sugar molecule, and a phosphate group. In nucleotides, the sugar molecule can be either ribose or deoxyribose, and all sugars are in their pentagon or furanose form. An example of a nucleic acid produced by the polymerization of ribonucleotides is ribonucleic acid. It is a single-stranded chain of ribonucleotides generated by 7 to 12000. There is a ribose sugar, a phosphate group, and a nitrogen base in this nucleic acid structure. Adenine (A), Guanine (G), Cytosine (C), and Uracil ( U) are the nitrogenous bases in RNA. By the 'transcription' process, RNA is produced from DNA and is usually involved in protein synthesis. Types of RNA are – Ribosomal RNA (rRNA), Transfer RNA (tRNA), and Messenger RNA ( mRNA). A is U complementary and G is C complimentary.

So the correct answer is option C.

Note: A codon is a DNA or RNA’s trinucleotide sequence that refers to a particular amino acid. The genetic code defines the relationship between a gene's sequence of DNA bases (A, C, G, and T) and the corresponding protein sequence it encodes. In groups of three bases, the cell reads the sequence of the gene. There are 64 different types of codons: 61 specify amino acids, while the remaining three are used as stop signs.
