4. An individual cell is able to make copies of its genetic information but is unable to produce encoded proteins. This indicates a possible problem in the_________________________. a. Centrosome b. Golgi apparatus c. Acrosome d. Ribosome
Homework Answers
Answer is Ribosome
Ribosomes are important in protein translation, as they attach on the mRNA. Ribosome is a very essential part of the translation machinery onto which there are the three sites for binding of tRNA onto which further peptides are added. This elongates the peptide chain and finally helps in production of the protein encoded by the gene.

1. The virus hijacks the cell, and RNA polymerases produce the complement to the positive stranded RNA genome. We can call these strands negative strands, and they then serve as templates for RNA polymerases to produce their complement. How does the sequence of these strands, the complement to the negative strands, compare with the original viral genome? 2-1. RNA polymerases lack proofreading ability. Define proofreading ability and describe its importance in replication of DNA genomes. a. Why is this a...
