Steps Of Protein Synthesis (Translation)
STEPS OF PROTEIN SYNTHESIS (Translation) TRANSLATION Translation is the process in which the genetic information stored in DNA is passed on to mRNA where it is translated into proteins. Translation occurs in ribosomes. mRNA is translated from its 5’ end to its 3’- end (51 à 31 ) 4 letter language information from nucleic acids

Acute myeloid leukemia (AML)
Acute myeloid leukemia (AML) ACUTE MYELOID LEUKEMIA (AML) AML is a heterogenous disease characterised by infiltration of malignant myeloid cells into blood, bone marrow. AML is due to inhibition of maturation of myeloid stem cells due to mutations. Seen in mainly in adults (50 years). Chromosomal mutations in AML are translocation t (8: 21) &
