Nucleus and DNA

Which one of the following process DOES NOT occur in the nucleus?

• DNA replication

• Protein translation

• RNA processing

• Transcription

According to the Central Dogma of Molecular Biology, the flow of genetic information in the cell is from

• DNA-> RNA-> Protein

• Protein->DNA-> RNA

• DNA-> Protein-> RNA

• RNA-> DNA-> Protein

The openings on the nuclear envelope that allows movement of molecules is called

• nucleolus.

• passive transport.

• nuclear pore complex.

• anchor proteins

A molecule that needs to move into the nucleus is

• exportins

• histone proteins.

• mRNA.

• tRNA.

Nucleolus is the site for producing

• anchor proteins.

• nuclear lamina.

• mRNA.

• ribosomes.

A nucleoid is

• the site for manufacturing ribosomes.

• a membrane bound organelle inside the nucleus.

• the region containing genetic material in prokaryotes.

• specialized pore opening on the nuclear envelope.

The nuclear pore complex

• is composed of 10 subunits.

• is located in the nucleolus.

• only allows movement by passive diffusion.

• has a central granule (transporter).

Bacteria chromosome is

• a linear molecule.

• circular

• in the nucleus.

DNA with histone proteins are called as

• plasmid.

• ribosomes.

• purine or pyramidine bases.

• chromatin.

Which one of the following is the most compact DNA structure?

• Double helix

• Chromosome

• Nucleosome

• Chromatin
