Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

19.3K
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%...

Energy Balance01:19

Energy Balance

1.4K
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...

Genome Copying Errors02:46

Genome Copying Errors

5.5K
DNA replication is a well-evolved process that copies millions of base pairs with high fidelity during each cell division. Occasionally a wrong base or a long stretch of wrong bases may get added to the daughter strands. If the errors are left unchecked, cells might accumulate several mutations that might endanger their  survival. Therefore, the copying errors are checked and repaired at three levels.

Real Time RT-PCR02:57

Real Time RT-PCR

66.8K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

Metabolic Rate01:25

Metabolic Rate

1.4K
The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...

Area of Science:

  • Genetics
  • Human Physiology
  • Genomic Variation

Background:

  • Copy number variation (CNV) at genomic loci is linked to human traits and diseases.
  • Replication of findings for CNVs has been a significant challenge in genetic studies.

Purpose of the Study:

  • To investigate the extent of variation at the amylase locus.
  • To re-evaluate the association between amylase gene copy number and body mass index (BMI).

Main Methods:

  • Analysis of copy number variation at the amylase gene locus.
  • Statistical assessment of the relationship between amylase gene copy number and BMI.

Main Results:

  • The study provides new data on the degree of variation present at the amylase locus.
  • Evidence suggests that the previously reported association between amylase copy number and BMI may not be robust.

Conclusions:

  • The variability of the amylase locus is characterized.
  • The association between amylase copy number and body mass index requires further investigation and validation.
