Cytogenetic method, Chromosomal and Karyotype analysis

Cytogenetic Method: Cytogenesis is the study of chromosomes and the related diseases states caused by abnormal chromosome number or structure. The basic mathod of obtaining chromosome preparation is-simple log in and initial setup-tissue culture(feeding and maintaining cell culture)-addition of a mitotic inhibitor to arrest cells at metaphase. Chromosomal and karyotype analysis: Karyotyping is the analysis […]

Protein synthesis

It simply means making protein. There are two process involved in making protein. Transcription and translation. Whenever cells want to make any type of protein they uses a process that includes building blocks like Amino acids to build new protein inside of the ribosome. anytime a cell want to make protein the instruction are transfered […]
