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...

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...

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.

Genomic Imprinting and Inheritance02:30

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...

Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

18.8K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Comparative Excretory Systems

26.7K
Animals have evolved different strategies for excretion, the removal of waste from the body. Most waste must be dissolved in water to be excreted, so an animal’s excretory strategy directly affects its water balance.

Area of Science:

  • Genomics
  • Population Genetics
  • Bioinformatics

Background:

  • Genomic comparisons are crucial for understanding divergence within and between species.
  • Investigating genomic differences in human subpopulations is vital for complex disease research, as genetic variants can be population-specific.
  • The 1000 Genomes Project provides extensive genome-scale variation data for diverse human populations.

Purpose of the Study:

  • To present a protocol for identifying population-specific variants using 1000 Genomes data.
  • To identify variants that potentially impact the proteome or RNA splice sites.
  • To explore biologically relevant genomic differences between human subpopulations.

Main Methods:

  • Utilizing the 1000 Genomes Project dataset.
  • Developing a step-by-step protocol for variant identification.
  • Analyzing identified variants for their potential effects on protein and RNA splicing.

Main Results:

  • A protocol for identifying population-specific variants was established.
  • The analysis focused on variants affecting the proteome and RNA splice sites.
  • Potential biologically relevant genomic differences between populations were highlighted.

Conclusions:

  • The protocol enables systematic identification of population-specific variants.
  • Understanding these variants aids in studying population-specific disease associations.
  • This approach facilitates the investigation of functional genomic differences across human populations.
