دلائل تثبت وجود ال ARNm

07 يوليو 2014

دلائل تثبت وجود ال ARNm :

· تقوم الكريات الدموية الحمراء ( بدون نواة أي غياب ال ADN ) بتركيب البروتينات.

· عندما تكون صناعة البروتينات عالية نجد كمية كبيرة من الـ ARN فيها.

· يسبق إرتفاع نسبة تصنيع البروتينات بإرتفاع في نسبة الـ ARN.

· ثقوب الغشاء النووي الرسول (ARNm ) هو الناقل للخبر الوراثي من النواة نحو السيتوبلازم حيث يتم تركيب البروتينات بوجوده.

إستنساخ سلسلة الـ ARN :

يتم إستنساخ سلسلة الـ ARN إبتداء من إحدى سلاسل الـ ARN بتحفيز من أنزيم نوعي هو الـ ARN – بولميراز.
