Answer:
may cause negative side effects
Explanation:
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
Gamete cells contribute to offspring because through meiosis, haploid cells with half of the chromosomes are created. They increase genetic variation by combining with the cell from the other organism. This contributes to offspring because they get good traits from both parents rather than being genetically identical to just one.
Hope that helped :-)
