1)Griffith = transforming principle Meischer = identified nucleus a acidic substance 2) biochemist 3) G1 S G2 M The cells go to G0 instead of S when they don't replicate G1 G2 M ARE CHECKPOINTS 3) Thomas kornberg
F.misher tells genetic material has acidic nature since ,coined the term "nuclein "so further named nucleic acid and then ribonucleic acid. F.griffith gave transformation principle in streptococcus pneumonia A.chargoff was biochemist . =Order of phases are Go,G1,s-phase,G2,m-phase . Also ,check points are first at the end of G1 phase and second at G2 phase
Mam apke qstns ne fr se puri ncrt pdhwa di🙏guru g tusi gr8 ho 1.F. Griffith-transforming principle F. Misher-1st one to isolate nucleic acid 2.Biochemist 3.G1/s and G2/M
Frederick Griffth transforming principle, Frederick meischer nuclein discovered, Erwin Chargaff biochemist and cell cycle check point are G1, S, G2, M phases 😊😊😊❤️❤️
Fredrich Meisher In the year 1869 considered DNA as an acidic substance present in the nucleus and names it 'nuclein'. Frederick Griffith did an experiement suggesting that bacteria are capable of transferring and gave us 'Transforming Principle'. E. Chargaff was a Biochemist
Frederic Griffith:- Explains transforming principle Frederic mischer:- 1st to isolate nucleic acid Erwin chargaff:- biochemist and also give rule of BASE PAIRING\CHARGAFF'S RULE\LAW OF EQUILITY OF BASE PAIRS Checkpoint in cell cycle:- G1/S and G2/M
Mam apke wajah se mujhe abhi iss ch me koi ek bhi doubt Nahi he Mene ye exam time me Dekha ur the best because u have covered all the topic in a simple way😍😍😘😘😍😍😍love you mam and may God bless you mam😘😘😍😍
Dna polymerase1 by Arthur kornberg DNA polymerase 3 by Thomas kornberg Erwin chargaff was a biochemist G1-G0,S,G2,M phases of cell cycle Check points are at G1-S phase and G2-M phase Friedrich Griffith gives transformation principle and Friedrich meischer identifies DNA as an acidic substance called as nuclein
1 _Mischer-- isolated nuclein in WBC. Griffith--1st to recognize DNA as a genetic material. Chargaff--Biochemist/logist. 3_G1-Sphase-G2phase-Mphase and GO is the checkpoint. 4 A.korenberg's enzyme---- DNA polymerase- I R.korenberg--studied transcription.
Actually the teaching was really good, but it would be nice if u teach only in English and not in Hindi 😒 bcoz I can't understand Hindi and I am from South India
Griffith explain that only DNA is genetic material by performing Transforming principle in (1928) And F.M Discover DNA in 1869 term was given by zacharis Not by F.M
really a nice lecture madam , so far i was not clear with this topic but after listening your teaching i completely understood everything madam thank you
1)Fredrick grifth... transforming principle ... Friedrich meischer 'nuclein' 1869 2)E.chargaff= biochemist 3)G1,G0,S,G2,M CHECK POINT G2 for DNA REPLICATION 4)DNA P 1=Arthur kornberg 1956 DNA P 3= Thomas kornberg, 1970
Erwin Chargaff was biochemist. Griffith did transformational experiment on mice. Meicher first found DNA as an acidic substance in nucleus named nuclein
Checkpoint in cell cycle : G1&M and G2 Erwin chargaff : biochemist by profession Frederick grifth : gives transforming principle and Frederick miescher : first scientist to isolate nucleic acid
1.😃Friedrich Griffith woh hai jinhone streptococcus pneumonia pe Experiment kiya tha.. Aur bataya ki koi transforming principle hai jo heat killed S se R type me jaa rha hai. 2.Friedrich Meischer wo hai jinhone Nuclein (acidic substance present in Nucleus) kaha.
1 . Fredrick M discovered nuclin in 1869. Fredrick G discovered dna as a transformant in 1928. 2.erwin chrgaff was a physicist.(hope so) 3. Parts of cell division g1,s,g2,m,g0 .m is again divided into prophase anaphase metaphase telophase. 4.dna polymerase 3 - Arthur kornberg Dna polymerase 1 - thomas kornberg
Mam u r awesome I am b.sc microbiology student but still I am following ur video to clear my n.ce.rt concept which was awesome awesome ♥️,mam u clear my concept clear crystal ,love u mam 🙏
Friedrich Griffith give transforming principal worked on mice about streptococcus pneumoniae infection Friedrich meischer first identified DNA c/d nuclein in 1869 Erwin chargaff - biologist Cell cycle phases - G1- S-G2-M DNA polymerase 1 Kornberg enzyme
Mam aapka padhane ka tarika to jabardast h but mam jo bacha shuru se hi hindi medium me padha h and then usne 11 me science li to uske liye to bahut mushkil ho jayegi itni english me padhna and mam same situation mere saath bhi hui thi mam jab me vedios dekhta tha to mujhe problem english me padhne me nhi thi ,jo teacher bacho ko samjhane me hindi ki bajaye english me bata rhe the unse thi to mam meri apse yhi request h ki bacho ko concept english me nhi balki hindi me samjh aate h
Hyee rabba 10 mint ta avdi trif ch h lnghaa dindi asi ethe km krn nu aye aa tuhadi trif sunnn nu nhi ik vr vr andi a subscribe krdo oh bhle loko subscribe ik vr h hunda a vr vr nhi
Maam i think u have said a wrong question. The question should be who discovered dna polymerase 1 and dna polymerase 3 . Is it roger kornberg or arthur kornberg The options should be thomas kornberg or Arthur kornberg Roger and thomas are sons of Arthur
