Advantages and Disadvantages and Applications of SSR Marker

Principle and Steps of SSR Marker

Simple Sequence Repeat or SSR Marker

SSR marker consider co-dominant inheritance marker with locus specific and multiple alleles and highly polymorphism with stability and reproducibility, SSR marker have scarcity polymorphic loci and low efficiency for massive samples because it require prior knowledge of DNA sequence at both ends of repeated motif therefore SSR marker consider expensive and time consuming marker, SSR marker use in genetic diversity studies and germplasm characterization and DNA fingerprinting profiling and genetic maps (Watch Related Video in #geneticteacher) #geneticteacher
Simple Sequence Repeat or SSR marker is microsatellite DNA marker cover almost entire genome with 18 to 25 of repetitive sequences of Primer, SSR marker initiate by extracting DNA for PCR amplification using fluorescent or regular primers and detect amplified DNA fragments with agarose gel electrophoresis to compare bands patterns (Watch Related Video in #geneticteacher) #geneticteacher

Types of STR Marker

Advantages and Disadvantages and Applications of STR Marker

Principle and Steps of STR Marker

Short Tandem Repeats or STR Marker

STR marker have two types (Autosomal STR provide information about inheritance from parents) (Sex chromosomal STR provide information about inheritance from males or females hence Y-STR marker found in Y chromosome and inherit in block without recombination as haplotype which use for exclusion and paternal lineage analysis (Watch Related Video in #geneticteacher) #geneticteacher
STR marker useful on degraded DNA and consider co-dominant and multiple alleles marker with highly polymorphic nature and stability inheritance on the other hand STR marker have poor bio statistical efficiency leading to possibility observe one or more genetic inconsistencies explained as mutational events, STR marker use in genetic diversity by demonstrating high mutation rates which leading to new alleles within population and DNA fingerprinting and paternity verification and genetic maps and linkage analysis and gene expression studies (Watch Related Video in #geneticteacher) #geneticteacher
STR marker initiate by DNA extraction and PCR amplification using fluorescent label primers and separate amplified DNA fragment by polyacrylamide gel electrophoresis or capillary electrophoresis to compare bands pattern with known STR profiles (Watch Related Video in #geneticteacher) #geneticteacher
STR sequence name by length of repeat unit (Mononucleotide repeats has one nucleotide repeated next to each other in repeat unit) (Dinucleotide repeats have two nucleotides repeated next to each other in repeat unit) (Tri-nucleotide repeats have three nucleotides repeated in repeat unit) (Tetra-nucleotides repeats have four nucleotides repeated in repeat unit) (Penta-nucleotides repeats have five nucleotides repeated in repeat unit) refer to different alleles with different number of repeats (Watch Related Video in #geneticteacher) #geneticteacher
Short Tandem Repeat or STR marker is microsatellite DNA marker occur when short sequence of DNA (1-7)bp repeated adjacent each other in row in genome resulting DNA segments 400 bp in length, (Short= Rang from (1-7)bp in length) (Tandem= Locate adjacent each other at specific locus) (Repeat= Repeat many times in chromosome) (Watch Related Video in #geneticteacher) #geneticteacher

Important and Applications of VNTR Marker

Principle and Steps of VNTR Marker

Variable Number Tandem Repeats or VNTR Marker

VNTR marker classify as highly polymorphic and co-dominant marker with multiple loci by creating banding pattern that is unique for each individual, VNTR markers use in genetic linkage studies by finding difference allele frequencies and genetic diversity within group of organisms and DNA fingerprinting by studying specific genes position for genetic map which may be useful in gene expression studies (Watch Related Video in #geneticteacher) #geneticteacher
VNTR marker initiate by extracting DNA and digest DNA with restriction enzymes to obtain multiple repeats sequence in form of bands on gel electrophoresis and hybridize by DNA probe to detect repeated sequence (Watch Related Video in #geneticteacher) #geneticteacher
Variable Number Tandem Repeats or VNTR marker is a minisatellite DNA marker with various tandem repetitions of specific sequence present on a variety of chromosomes between individuals cluster and oriented together in same direction (Watch Related Video in #geneticteacher) #geneticteacher
