How to Analyse DNA in Genetic Genealogy

DNA has many uses in genealogy, and there are two main ways that DNA is tested in order to create a profile of your genetic make-up. In genealogy, 3 main DNA types are tested and analysed, those DNA types are:

    Autosomal – Distant past, used in ancestrymtDNA – Tests the direct maternal lineY-DNA – Tests male direct paternal line

Two types of test can then be completed on the DNA; STR’s (Short Tandem Repeats), also known as Microsatellites and SNPs (Single-Nucleotide Polymorphism).

STRs are repeating sequences of 2-6 base pairs of DNA.

Excretion in Plants

Introduction to excretion in plants

Excretion is the process of elimination of waste materials from the body. Excretion in plants is much simpler than that of animals and as such it does not pose any serious problem in plants. There are several reasons for this:-

1. The rate of catabolism is comparatively much slower in plants than in animals having the same body weight and consequently the rate of accumulation of body waste is much slower.

The Various Properties of Titanium

While titanium is not a new metal it continues to be one that industries look to for strength and durability. With a high specific strength (comprised of the ratio of tensile strength to density), titanium is 45% lighter than steel and 60% heavier than aluminum. With uses ranging from being used to make white paint to helping produce artificial gems, titanium is widespread across a number of industries and used in a number of different ways.

Chemical Properties:

Titanium does not oxidize quickly nor does it corrode quickly in water.

Have you ever read the newspaper and there was a story about a police officer shooting someone they’d been chasing because it looked like they were going to pull out a gun, and instead it was their wallet to show ID, or worse a kid with a toy gun? Yes, it happens, and we all cringe when it does.

How to Save Money by Purchasing Used Centrifuges

Small labs, startup clinics, and hospices usually look up for ways to save money on the purchase of lab equipment. Buying used centrifuges which has been refurbished and recertified to meet the highest quality standards can help save a lot of money. Established laboratory equipment stores offer an excellent cost saving alternative by providing used centrifuges at a fraction of the cost of new devices.

Used Medical Centrifuges a Reliable Option

Used lab centrifuges are ones that have been returned to the supplier due to a small defect or devices that have been sold off by labs that are replacing them with more advanced models.

The History of MtDNA and the Story of Mitochondrial Eve

Mitochondrial DNA (or mtDNA) is the DNA we inherit from our Mothers, and is held in a unique circular strand in small tubular packets known as mitochondria that function in a similar way to batteries in the cytoplasm of cells. If you were to trace the matrilineal line all the way back to the most recent common ancestor you’d reach the DNA of Mitochondrial Eve.
