please give me some idea that why only RNA primer used in DNA replication ?

hello sir according to basis of size or by any mean.

hello sir i am apologise for my mistake.actually i want to know that sepration of DNA on water thanks for correction

is it possible that we can isolate DNA on water instead of gel?

hello sir Before Newton every one knows that apple fall on earth But he was the only guy who observe it keenly & gave the concept of GRAVITY. I am very keenly observing this thread & i noticed that people thought that this thread is useless. but i am great beliver of science. i think that science world is the only place where you can findout the answer's of what, why & how? and i came to know the answer of this thread by the help of CharonY & other members of this forum. and i am very thankful to these peoples. think that if the uracil is replaced by thymine in the RNA artificially what will be the impact on RNA. Thanks for your sugession tRNA is transfer RNA not because it is important in protein synthesis. it is transfer RNA because it transfer the amino acid in translation. Like that everything which is going on, has some reasons. I want only healthy disscusion. i am apologise if i hurt you or anyother person.I will always try to make sure that no one will hurted by me.My intention is only to know the reasons by the help of science. and one thing more that i am not good in english.and i think that english is not require to know the science. once again thankyou very much.

hello according to the work of Drs fei & Ganapathy Indy delivers metabolic substrates such as citrate and succinate to cells where they enter the powerhouse called the mitochondria. Inside the powerhouse, oxygen also is critical to the biochemical reaction that occurs to produce ATP, the fuel for cells, says Dr. Fei, molecular biologist. Indy gene is only one of the life-determinant genes. But when the function of this single gene is knocked down, the animal can extend its lifespan."

hellow sir you gave me very important information. thank you bye & take good care of your self

after splicing in hnRNA during post transcriptional modification what is the fate of intron? If they don't have any information in terms of protein then what is the role of intron ? kindly give me some idea.

hello if red flower crosses with white flower it is expected that red flower comes in F1 generation because red is dominant over white according to mendel's law. But in case of 4 o' clock (plant name) pink colour flower comes in place of red because of incomplete dominance of red over white. it comes but not fully.

hello sir can you explain me the experiment of yours or tell me the result of your experiment.so that i can give you some idea(may be). thank you

Hello sir/madam Pedigree analysis demonstrated a mechanism by which a recessive allele in a homozygous state could be responsible for the disorder. The condition in these calves was considered the result of a recurrence of a genetic mutation affecting a putative hemimelia locus.

Structure of tRNA Structure of tRNA. CCA tail in orange, Acceptor stem in purple, D arm in red, Anticodon arm in blue with Anticodon in black, T arm in green.tRNA has primary structure, secondary structure (usually visualized as the cloverleaf structure), and tertiary structure (all tRNAs have a similar L-shaped 3D structure that allows them to fit into the P and A sites of the ribosome). The 5'-terminal phosphate group. The acceptor stem is a 7-bp stem made by the base pairing of the 5'-terminal nucleotide with the 3'-terminal nucleotide (which contains the CCA 3'-terminal group used to attach the amino acid). The acceptor stem may contain non-Watson-Crick base pairs. The CCA tail is a CCA sequence at the 3' end of the tRNA molecule. This sequence is important for the recognition of tRNA by enzymes critical in translation. In prokaryotes, the CCA sequence is transcribed. In eukaryotes, the CCA sequence is added during processing and therefore does not appear in the tRNA gene. The D arm is a 4 bp stem ending in a loop that often contains dihydrouridine. The anticodon arm is a 5-bp stem whose loop contains the anticodon. The T arm is a 5 bp stem containing the sequence TΨC where Ψ is a pseudouridine. Bases that have been modified, especially by methylation, occur in several positions outside the anticodon. The first anticodon base is sometimes modified to inosine (derived from adenine) or pseudouridine (derived from uracil). hello, The cloverleaf model of tRNA shows that tRNA contains three non-base-paired loops: D, anticodon, and TpsiC loop my question is that in TpsiC loop why T is presnt.BEfore giving any answer please know the stucture of tRNA hello, i am sorry to say that you have to check the three dimensional structure of tRNA and then tell me . The cloverleaf model of tRNA shows that tRNA contains three non-base-paired loops: D, anticodon, and TpsiC loop my question is that in TpsiC loop why T is presnt.BEfore giving any answer please know the stucture of tRNA hello YOU have to know that tRNA is the only RNA which contains Thymine. The T arm is a 5 bp stem containing the sequence TΨC where Ψ is a pseudouridine and T is Thymine. ok and my question is on this T. hello you should know sir that tRNA is the only RNA which contains Thymine. The cloverleaf model clearly shows that tRNA contains three non-base-paired loops: D, anticodon, and TpsiC loop. The T arm is a 5 bp stem containing the sequence TΨC where Ψ is a pseudouridine & T is a Thymine.

latteral meanig of affinity is atraction. Afinity chromatography works on this principal. Sepration on the basis of positive ions or negative ions. Supose for the sepration of DNA we have to prepare the medium which contains positive ions because DNA is negatively charged. so that it binds with the medium and rest of the materials passes out.

why only tRNA contain thymine? What is the role of Thymine in tRNA?

Mendel's law of dominance is different from law of purity.And you are talking about law of dominance as well as law of purity simultaneously.Hetrozygous always have two different alleles. In F2 generation on self pollination genotypicaly they segregate acording to the 1:2:1.that is law of segregation.

If someone has deffective gene. It doesn't mean that he can inherit that particular gene into his/her offspring.but the chances of inheritance is high.it is all depend upon the parents whether one parent has deffective gene or both have the defective gene in case of X linked gene. But in case of Y linked inheritence it is certain that male offspring have the deffective gene.
