 यस तर से एश्वंटर यह दो जिनेटिक मीटरिल है लगा दीने ही है इसी के पास तमांत तरा के अन्फरमेशन टोर हैं तो वूग यक शे दीने यह यजेनेशिए ब्रिल दीने ही प्रेषिपल जिनेटिक मीटरिल है प्रोटीन, लिप्ट, कार्बो, ही देट्स में से कोई भी जिनेटिक मिल के रोल, नहीं प्लेग करता हैं दा अनीमल्स। अब जिनेटिक मिल के अगर आम बात करते हैं दीनने is a very long thread. दीनेग बोध बडा फाइबर हैं और इसके दीनेग को गर अग्र तो इसके different fragments यह देट्विन पोशन्स जोगें वो different proteins को अच्टिशाँ सेद्चाइस करवात थे यह आशाएंप को सेथट्चाइस करवाते हैं। आग हैं जो दखलुरि� उला, , जब सल निये में लिएड करना है, तो सल दिवीण करने से भर नहीं से फने ष्डविएन ख़ोत नहीं से ख़ोंगे जब कोरमाटन फाभः कर भीर एक अपने अपस को ममेचीद कन ड़ेँस करेगा, दित बल ख़ा ग़ँच करन दिएऔर क्रोमोजों ती लगाँ सोग कर शब � दा दिनटिक मेंटीरिल, तो नोग वॉरे सत्तौछट़ इस भ मननन चाईय नागुग लोग भो दोगान करोमोज्म। तो गॉस केगण नेट्टीक मिटीलियि क्रोमेंटिन्ट् मेटीर्ग है, at the time of cell division, the cell division starts before it is condensated which is in the form of a network of chromatin fibres before cell division, they are assembled properly so that they do not break up they do not break up the chromatin fibres when the chromatin fibres condensate, the shape of the chromosome appears the number of chromatin fibres is the same number of chromosomes that exist in the cell because one chromatin fibre will be condensated and one chromosome will be formed so if there are 46 chromosomes in the human, this means that when our cells divide then before the 46 chromatin fibres, before the division and at the time of the division, they condensate 46 chromatin fibres and make 46 chromosomes in this way, the fruit flies in the drosophila, there are 8 chromatin fibres in a cell these are the 8 chromatin fibres when the cells divide and condensate and make 8 chromosomes so the number of chromatin fibres is equal to the number of chromosomes now the number of chromosomes is very specific in each species every animal species has a specific number of chromosomes like in the human, the number of chromosomes is 46 so if the number of chromosomes is more than 46, then this will be abnormality and if we deviate too much, then this animal species can not exist there are 48 chromosomes in the chimpanzees in the fruit flies, which we call drosophila the number of chromosomes in the drosophila is number 8 this is the P plant, the plant of the P plant which Mandel had experimented the number of chromosomes is 14 so here we have the structure of the chromosome usually when you look at the structure in the books when you look at the diagram, there is a structure of something like this this is a chromosome students, this is not a single chromosome, this is a duplicated chromosome when the cell division is to be done, then before the cell division the shape of the actual chromosome is the shape of a single fiber the diagram that you are looking at is a chromatin, this is a whole chromosome but the time of the cell division, the chromosome duplicates itself if we look at the different parts of the chromosome first of all, in the center of the chromosome there is a constriction thin area, we call it centromere it is also called centromere and apart from centromere, it is also called primary constriction primary constriction similarly, in the center of the chromosome primary constriction similarly, the one arm of the chromosome is thin and the other arm is long so the smaller portion, we call it P arm P arm we call it arm, there are two sides of the chromosome P and the Q similarly, the ends of the chromosome we call the end of the chromosome as telomeres telomeres are actually the ends of the chromosomes now, the shape of the chromosome can be different in the FSC if the centromere and the Q arm are exactly the same so the centromere in the center we call it metacentric if one arm is smaller, the other is larger as you can see in the diagram we call it submetacentric similarly, if one arm is very small then we call it acrocentric acro means something small so small arm as you can see in the diagram if one arm is very small, then we call it acrocentric and if one arm is not there then we call it telocentric
