Title: Isolation of plant DNA from onion Introduction DNA is the hereditary material of all living organisms and therefore the isolation of DNA is essential to geneticists and molecular biologists and scientists interested in studying hereditary diseases. Almost all cells contain DNA, but not all have equal amounts and therefore …

What is the Amount of DNA Extracted from Different Fruits?

Hypothesis: The DNA extracted from the strawberry will be the greatest amount due to their softness and pulverization. They have large genomes being an octoploid. This means that they have eight of each type of chromosome in each cell. Thus, the strawberry should provide the most DNA. Procedure: I used …

Should you Have to Provide a DNA Sample to Enroll in FCPS?

Research in Cloning Summary

What is cloning? Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. It describes the processes used to create an exact genetic replica of another cell, tissue or organism. The copied material, which has the same genetic makeup as …

DNA Base Pairing

In every base pairing, a Purine always pairs with a Pyrimidine. In DNA replication, the DNA strands pair with its complementary base. A purine pairs with a Pyrimidine. The Purines are: Adenine (A) and Guanine (G).  they have a larger molecular structure than pyrimidines. The pyrimidines are Cytosine (C) and …
