Question
Styles - Eveny cell in an organism has the same - Individuals differ from each other in - The most common genetio variant genetic material and cach human has an almost identical genome. regions that are variants of each other SNP between individuals are single mneleotide polymorphisms (SNPs), which is a genetic difference of the BNA sequence tn just a single base. There ave millions of SNPs distinguishing Lndbviduals from each other. Figure3. SNP -suearyotie cells are alfferent from each other by only expressing (produing, synthesizing, making proteins from certain genes ofthe genome. The expression of enearyotio genes cance regulated at step along the pathway fron PNA to acatcis NA-SuiRaExplanation / Answer
Answer:- Expression of a particular protein means in what way those proteins are synthesized, modified and regulated in living organisms. Proteins are synthesised as per cell need and blueprints for particular proteins are stored in DNA which is then transport this information to messenger RNA ( m- RNA) by process of transcription followed by translation process where the synthesis of protein occurs based on a sequence specified by mRNA.
This process of expression of a particular protein regulated at multiple steps such as:-
Chromatin availability:- Here more open or available chromatin (DNA)makes a gene blueprint more available for transcription lead to higher or lower expression of a particular protein in the further process.
Transcription:- During transcription, sets of transcription factors proteins those bind to particular DNA sequence promote or repress its transcription into RNA.
Transport from nucleus:- All RNA molecules are regulated so they can transport from nucleus to cytoplasm for the process of translation. Here slicing of m-RNA contribute to higher or lower expression of a particular protein.Again lifetime and stability of m-RNA affect how many proteins can be made from it.
Translation:- The process of translation is regulated by regulatory factors affecting expressions of particular proteins.
