Topics of Interest for Submission include, but are Not Limited to:
This area focuses on the structure, function, and regulation of macromolecules essential to life, centering on the "Central Dogma" of molecular biology.
Nucleic Acid Structure and Biochemistry
DNA double helix structure, alternative conformations (A, B, Z DNA)
RNA types (mRNA, tRNA, rRNA, snRNA, miRNA, lncRNA) and secondary structures
Nucleosome structure, chromatin packing, and histone modifications
DNA Replication and Repair
Mechanism of semi-conservative replication (initiation, elongation, termination)
Replication fork dynamics, DNA polymerases, and okazaki fragments
Telomere maintenance and telomerase function
DNA damage and repair pathways (Mismatch repair, Base Excision, Nucleotide Excision, Double-Strand Break repair)
Transcription and RNA Processing
Prokaryotic vs. eukaryotic transcription mechanisms
Promoters, enhancers, transcription factors, and RNA polymerases
Post-transcriptional modifications: 5' capping, 3' polyadenylation, and constitutive/alternative splicing
Translation and Protein Synthesis
The genetic code, codon bias, and wobble hypothesis
Ribosome structure and the phases of translation (initiation, elongation, termination)
Post-translational modifications (phosphorylation, glycosylation, ubiquitination) and protein folding chaperones
Genetics bridges the gap between molecular mechanisms and organismal traits, exploring how genetic information is passed down and modified.
Transmission (Classical) Genetics
Mendelian laws of inheritance (segregation, independent assortment)
Non-Mendelian inheritance: Incomplete dominance, codominance, lethal alleles, and epistasis
Sex-linked inheritance, pedigree analysis, and genetic mapping
Cytogenetics and Chromosomal Biology
Karyotyping and chromosome morphology
Chromosomal aberrations: Aneuploidy, polyploidy, deletions, duplications, inversions, and translocations
Meiotic recombination, non-disjunction, and crossing over
Gene Regulation and Epigenetics
Prokaryotic gene regulation (operon models like lac and trp)
Eukaryotic transcriptional regulation, chromatin remodeling, and pioneer factors
Epigenetic mechanisms: DNA methylation, genomic imprinting, and X-chromosome inactivation
Population and Evolutionary Genetics
Hardy-Weinberg equilibrium and forces causing deviation (mutation, migration, genetic drift, natural selection)
Quantitative genetics: Polygenic traits, heritability, and QTL mapping
Molecular evolution, phylogenetic analysis, and speciation
Cell biology studies the structural components of cells, how they maintain homeostasis, and how they interact with their environment.
Cellular Membranes and Transport
Fluid mosaic model, lipid raft composition, and membrane fluidity
Passive transport (simple and facilitated diffusion, osmosis)
Active transport (primary/secondary active transport, endocytosis, exocytosis)
Organelle Structure and Function
Nucleus: Nuclear envelope, pore complexes, and nucleolus
Endomembrane system: Rough/smooth endoplasmic reticulum, Golgi apparatus, and lysosomes
Energy transducers: Mitochondria (oxidative phosphorylation) and Chloroplasts (photosynthesis)
Peroxisomes, vacuoles, and proteasomes
Cytoskeleton and Cellular Motility
Microtubules, microfilaments (actin), and intermediate filaments
Motor proteins (kinesin, dynein, myosin) and intracellular transport
Cilia, flagella, and cell migration mechanisms
Cell Signaling and Communication
Types of signaling (autocrine, paracrine, endocrine, juxtacrine)
Receptor classes: G-protein coupled receptors (GPCRs), Receptor Tyrosine Kinases (RTKs), ion channel receptors, and intracellular receptors
Second messengers (cAMP, Ca2+, IP3/DAG) and kinase cascades (MAPK, PI3K/Akt)
These topics represent the massive overlap where molecular mechanisms directly dictate cellular behavior and genetic outcomes.
The Cell Cycle, Mitosis, and Meiosis
Phases of the cell cycle (G1, S, G2, M)
Cell cycle checkpoints (G1/S, G2/M, spindle assembly) and cyclins/CDKs
Mechanisms of mitosis (somatic division) vs. meiosis (germline division and genetic diversity)
Cell Death, Aging, and Cancer Biology
Apoptosis (intrinsic and extrinsic pathways), necrosis, and autophagy
Cellular senescence, telomere shortening, and aging
Oncogenes, tumor suppressor genes (e.g., p53, Rb), and the hallmarks of cancer (metastasis, angiogenesis)
Developmental Biology and Stem Cells
Cell potency: Totipotency, pluripotency, multipotency
Embryonic stem cells vs. induced pluripotent stem cells (iPSCs)
Morphogens, homeobox (Hox) genes, and pattern formation during development
Immunology and Host-Pathogen Interactions
Innate vs. adaptive immunity at the cellular level (T-cells, B-cells, macrophages)
V(D)J recombination (genetic rearrangement for antibody diversity)
Viral replication cycles and bacterial defense systems (e.g., CRISPR-Cas systems in nature)
