what is functional difference between DNA and RNA?

Answer 1

D.N.A. is double stranded. R.N.A is single strandedD.N.A. uses the nucleic acid component Thymidine, and R.n.a. uses uracil in its stead. D.N.A. resides in the cell nucleus, R.N.A. spnds most of its time in the cell cytoplasm. There is messenger, tansfer, ribosomal, and satellite R.N.A.
D.N.A. does not have counterparts to those R.N.A.'s

Answer 2

The functional difference between DNA and RNA is that DNA is the permanant record of all of the genetic information for an individual. RNA is a temporary copy of a portion of that record as it is needed to code for synthesis of a particular protein which the cell needs at that time. DNA resides in the cell nucleus and maintains its integrity for the life of the cell. RNA exhists in three forms: Messenger RNA. Transfer RNA, and ribosomal RNA. Ribosomal RNA is attached to the ribosomes and is involved in protein synthesis. Transfer RNA is attached to single amino acids and transfers them to a forming polypeptide (porotein) as dictated by the messenger RNA which brings the code for a given polypeptide from the DNA to the ribosome complex for protein synthesis. RNA contains an extra OH group on the sugar moiety which DNA does not have. This extra oxygen exerts a pull the electrons in the phosphate bonds thus destabiling RNA to some extent which facilitates disassembling the RNA after it has surved its purpose and there is no need for synthesis of that particular protein at that time. This serves to keep the cytoplasm from getting clogged with a lot of excess RNA and the nucleotides may be reused when again needed.

Answer 3

DNA stores information and RNA executes information. You could think about it in computer terms like the difference between the hard drive (DNA) and RAM (RNA). An mRNA transcript copies the information contained in DNA so that a protein can be made, but differences in its chemical structure cause it to be degraded much more quickly than DNA, leaving you with just the original information (DNA) and the executed output (a protein).

Answer 4

What the previous answers have said are all correct, but additionally other more recent findinds have also shown that RNA can have direct functions on cellular activity like being part of the ribosomal subunits, transfering amino acids to the ribosome and even being involved with gene regulation. DNA appears to only have one function in humans, as a molecular blueprint.

Answer 5

1st living organism had rna led to dna formation by changin uracil by thymidine. Then multicellular beings developed . They evolved with mutations. The viral strandscan be found in human dna. Dna s like master copy in nucleus . The information s transferred by transcription into proteins via 7rna n they act as buildin materials . Rna s like wire connection.bw dna and protein

Answer 6

DNA is what stores our genetic information. It is the ultimate copy of our genes.

When you transcribe the information from DNA, its takes the form of RNA. RNA has different types: rrna (ribosomal), trna (transfer), mrna (messenger rna). RNA seems more versatile, and it is less bad if there is an error in RNA bc it isnt the ultimate copy of our genetic information.

The central dogma of molecular biology:
DNA---> RNA----> protein

DNA--> RNA takes place in the process of transcription

RNA--> protein takes place in the process of translation

Answer 7

DNA is like the hard copy of your genetic makeup. RNA is a temporary copy of a gene encoded by the DNA which is used as a template to synthesize a number of protein molecules after which it is destroyed.

Answer 8

DNA is the Genetic Blue print
DNA does not leave the nucleus of the cell
RNA is the messenger that does leave the nucleus and carries the information with it

Answer 9

dna has thyamine
and rna has uracil

remember the AGCT for DNA and AGCU for RNA ?

Answer 10

In simple terms easy to understand.

DNA is the blueprint, it functions in two ways. One being mitosis the other is protein synthesis.

RNA is the messenger.
