Chapter 4, Problem 8SQ
Summary Introduction
To determine: The order of the flow of the genetic information in the cell.
Introduction:
The genetic information of a cell is stored in the form of the DNA (deoxyribonucleic acid) in the nucleus of the eukaryotic cells. The external signals from the cells signal the genes to pass the genetic information and translate it into the proteins. The genetic information is then passed on to different organelles.

Which is NOT a true difference between messenger RNA and DNA? (i.e., which of the following statements is false?)
DNA remains in the nucleus (except when the nuclear envelope breaks down during mitosis), whereas mRNA is never in the nucleus; it is always in the cytoplasm.
A DNA molecule has a longer life span than a typical molecule of RNA.
DNA has thousands of genes; mRNA is usually a copy of just one gene.
DNA has thousands of genes; mRNA is usually a copy of just one gene.
Choose the CORRECT processes that take place inside a nucleus.
Select one:
RNA splicing and translation.
Translation and DNA replication.
Transcription and translation.
RNA splicing and transcription.
Briefly describe the structure and function of each of the following: plasma membrane, chromatin, nucleus, nucleolus, rough endoplasmic reticulum (rough ER), Golgi complex, lysosomes, mitochondria, microfilaments, microtubules, intermediate filaments, centrioles, basal body (kinetosome), tight junction, gap junction, desmosome, glycoprotein, microvilli.
