In this article we will discuss about:- 1. Concept of DNA 2. Structure of DNA 3. Unusual Bases 4. Replication. Concept of DNA: DNA is present in the cells of all plants, animals, prokaryotes and in a number of viruses. In eukaryotes (e.g., Escherichia coli, a bacterium) the genetic material consists of a single giant molecule of DNA about 1,000 [...]
The following points highlight the top ten types of DNA markers. The types are: 1. Restriction Fragment Length Polymorphism 2. Amplified Fragment Length Polymorphism 3. Random Amplified Polymorphic 4. Cleaved Amplified Polymorphic Sequences 5. Simple Sequence Repeat (SSR) Length Polymorphism 6. Heteroduplex Analysis 7. Single Nucleotide Polymorphism 8. Single Nucleotide Polymorphism and Others. Types of DNA Markers: Restriction Fragment Length [...]
In this article we will discuss about:- 1. Definition of DNA Markers 2. Properties of DNA Marker 3. Applications of DNA Marker in Crop Improvement. Definition of DNA Markers: Those characters which can be easily identified are called marker characters. Any genetic element (locus, allele, DNA sequence or chromosome feature) which can be readily detected by phenotype, cytological or molecular [...]
