If an organism had a mutation in a gene that codes for ribosomal protein, which of the following would be affected ?
a) dna replication
b) transcription
c) translation
d) gene expression

The answer is C. translation.
Translation is a process of a protein synthesis based on the ribonucleotide sequence of messenger RNA (mRNA). During translation, mRNA attaches to a complex molecular machinery ribosomes. Ribosomes consist of two subunits - a small and a large one. The small subunit reads mRNA sequence, while the large one joins amino acids brought by transport tRNA. The sequence of a newly synthesised protein depends on the sequence of mRNA and complementarity between mRNA and tRNA. Therefore, if a mutation in a gene that codes for ribosomal protein occurs, the new protein will not be synthesised, i.e. the translation will be affected.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
