Ans. (4). protein synthesis.
Protein synthesis can be defined as a process that involves formation of polypeptides or proteins by using information present in DNA. It is divided into two steps, transcription and translation.
During transcription, DNA is transcribed into mRNA and information present in DNA is transferred to mRNA as codons. Codons represent triplet of nucleotides and each codon codes for a specific codon.
Translation involves formation of protein, during which amino acids are added to the growing polypeptide chain with the help of codons.
The given diagram represents process of translation. Thus, the correct answer is option (4).
Answer:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
The mRNA codon GAG corresponds to the tRNA molecule that can carry more than one amino acid <span>is one possible reason that Mutation 2 leads to the production of normal blood cells rather than the sickled blood cells.</span>
Comparison of meiosis and mitotic cell division. As in the previous figure, only one pair of homologous chromosomes is shown. In meiosis, after DNA replication, two nuclear (and cell) divisions are required to produce the haploid gametes.
