2.1: BIS2A Success Tips
2.2: The Mitotic Cell Cycle
2.3: Meiosis
The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. In mitosis, both the parent and the daughter nuclei are at the same ploidy level—diploid for most plants and animals. Meiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is typically diploid and the nuclei that result at the end of a meiotic cell division are haploid.
2.4: Mendel's Inheritance
Gregor Mendel is (now) famous for having discovered the concept of genes (though he simply called them “factors”).
2.5: DNA Replication
2.6: Transcription
2.7: Translation
The process of translation in biology is the decoding an mRNA message into a polypeptide product. Put another way, a message written in the chemical language of nucleotides is "translated" into the chemical language of amino acids. Amino acids are linearly strung together via covalent bonds (called peptide bonds) between amino and carboxyl termini of adjacent amino acids.
2.8: Protein Localization
In this section we will discuss two major modes of protein localization. We will begin with the components of the endomembrane system. This system involves co-translational translocation across membranes, and later delivery and processing through various organelles via vesicles and motor protein-mediated transport. It is employed for proteins that function within the compartments of the endomembrane system, for proteins embedded in the plasma membrane, and for secreted proteins.
2.9: Mutations
Here we describe the origin of mutations, their effects on gene expression, and their ultimate role in evolution.
2.10: Regulation of Gene Expression
Regulation is all about decision making. Gene regulation is, therefore, all about understanding how cells make decisions about which genes to turn on, turn off or to tune up or tune down. In the following section we discuss some of the fundamental mechanisms and principles used by cells to regulate gene expression in response to changes in cellular or external factors. This biology is important for understanding how cells adjust changing environments.
