DNA t ranscription :-   Transcription is the first step in  gene expression , in which information from a  gene  is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or  transcript , carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.  We can’t teach DNA transcription and translations without knowing the three main RNA’s : 1-     Messenger RNA  ( mRNA ) Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression . genotype : Your  genotype  is your complete heritable genetic identity; it is your unique geno...

مدونتي راح تتخصص بالmolecular biology  و biotechnology science  :- و هو علم يتخصص بال DNA و دراسة علم الوراثه و يندرج ضمنه علم البايوتكنولوجي و هو  علم يهتم بدراسة الصفات الوراثيه و كيف يمكن معالجة المنتجات لتصبح افضل من حيث الهيئه و الطعم و القيمة الغذائيه سواء بالنباتات او الحيوانات و هو علم مهم من الجانب الطبي ايضا بصناعة الادويه و اللقاحات لمحاربة الامراض و تحديد الامراض الجينيه  . و سوف تكون مدونتي باللغه الانقليزيه  lets start with molecular biology :) first we will begin with the basics :) The cell With in the cell nucleus is the observable genetic material known as the chromosomes. In body cells chromosomes are found in pairs (Half from the female parent and half from the male parent.) In reproductive cells/gametes, they occur in a single set called haploid and represented by n but in body cells they occur in a double set called diploid and represented by 2n. : we have two different kind of c...
