Resumen
Los estudios de ADN antiguo ahora pueden secuenciar genomas de osos de cuevas extinguidos usando metagenómica. Este avance permite un análisis evolutivo detallado de especies antiguas a partir de ADN no amplificado.
Área de la Ciencia:
- La paleogenómica es la paleogenómica.
- Investigación de ADN antiguo Investigación de ADN antiguo.
- Biología evolutiva Biología evolutiva.
Sus antecedentes:
- El ADN mitocondrial (mtDNA) ha sido el foco principal de los estudios de ADN antiguo debido a su alto número de copias.
- El ADN genómico ofrece significativamente más información, pero presenta mayores desafíos para la recuperación y el análisis de muestras antiguas.
- Los métodos anteriores estaban limitados en su capacidad para recuperar y analizar material genómico antiguo no amplificado.

01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

01:05Single Nucleotide Polymorphisms-SNPs
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
01:05Maxam-Gilbert Sequencing
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
