Ribosomal RNA is produced by nucleolus<span>. Ribosomal RNA associates with a set of proteins to form ribosomes. They physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. Additionally, they bind tRNAs and various accessory molecules necessary for protein synthesis. Nucleolus is the structure within the nucleus that is responsible for the formation of these complex structures. The DNA is transcribed into ribosomal RNA precursor molecule which is later processed into mature rRNA. </span>

Zina [86]

Answer:

A) A transgene integrated into a heterochromatic region of the genome.

Explanation:

This is most likely the reason why the transgene is not expressed in the fifth cell line. It is likely that the transgene was integrated into a heterochromatic region of the genome. Heterochromatin consists of genetically inactive satellite sequences, and many of these are repressed to various extents. Moreover, because this is a tightly packed form of DNA or condensed DNA, it is inaccesible to polymerases and thus not transcribed.
