Genomics

40.9K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genomic Imprinting and Inheritance

37.3K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Genome Size and the Evolution of New Genes

9.2K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Overview of Advanced Functional Groups02:22

Overview of Advanced Functional Groups

30.4K

Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.

Extraction: Advanced Methods

1.2K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes02:16

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

17.1K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Area of Science:

  • Behavioral genomics
  • Genetics
  • Evolutionary biology

Background:

  • Animal behavior is linked to gene expression, suggesting genetic limitations on environmental responses.
  • The precise timing and regulation of environmentally responsive gene expression remain poorly understood.
  • Behavioral genomics investigates the relationship between gene expression dynamics and the stability of behavioral traits.

Purpose of the Study:

  • To explore how genomic regulatory mechanisms predict the timescale of environmental impacts on behavior.
  • To bridge the gap in understanding the temporal dynamics of environmentally induced gene expression.
  • To inform organismal and evolutionary questions regarding trait plasticity and early life stress.

Main Methods:

  • Investigating correlations between gene expression dynamics and behavioral lability.
  • Analyzing genomic regulatory mechanisms.
  • Employing a temporally focused approach to behavioral genomics.

Main Results:

  • Gene expression dynamics are correlated with behavioral trait stability and lability.
  • Specific genomic regulatory mechanisms may dictate the speed of behavioral responses to environmental cues.
  • This temporal perspective offers insights into the evolution of phenotypic plasticity.

Conclusions:

  • Genomic regulation plays a critical role in the timing of behavioral responses to environmental factors.
  • Understanding these dynamics is key to addressing issues like early life trauma and the evolution of adaptability.
  • A time-aware approach in behavioral genomics can yield significant insights into fundamental biological questions.
