3 differences between RNA and DNA?

Answer 1

DNA has a deoxyribose sugar; RNA has ribose sugar.

DNA is double stranded; RNA is single.

DNA has adenine that pairs with thymine, guanine that pairs with cytosine; RNA has adenine that pairs with uracil, guanine that pairs with cytosine.

DNA resides in the nucleus; RNA resides in both the nucleus and the cytoplasm (near ribosomes)

Answer 2

1. DNA is double stranded, RNA is single stranded (only true in cells - viruses can also use single stranded DNA and double stranded RNA)

2. DNA contains deoxyribose sugar, RNA contains ribose sugar

3. DNA contains thyamine base, RNA contains uracil base

Answer 3

All cellular (living) organisms contain both DNA and RNA. Viruses, which are generally not considered to be living, contain one or the other.

Here are some major differences between RNA and DNA:

• With the exception of a few viruses, RNA is a single-stranded molecule while DNA is double-stranded. The two DNA chains are connected by hydrogen bonds between nitrogenous bases.
• DNA is replicated during cell division; RNA is not.
• The function of DNA is the storage of hereditary material ― the "blueprints" of an organism and the proteins it synthesizes. The types of proteins determine the traits of the individual. RNA functions in transferring DNA's code to the ribosomes where proteins are made.
• Both contain a sugar, phosphate groups, and four different nitrogenous base pairs. Three of the nitrogenous bases are the same for both RNA and DNA: guanine, adenine, and cytosine. Thymine, the fourth base pair found in DNA, is replaced by uracil in RNA.
• DNA has deoxyribose sugar while RNA has ribosesugar. The deoxyribose sugar has one less oxygen atom than the ribose sugar.
• DNA is longer than RNA because DNA contains all the genes of the organism and more besides. RNA is only long enough to code for a specific gene within DNA.
• In eukaryotic cells, DNA is only found in the nucleuswhile RNA can be found both in the nucleus and in the cytoplasm.
• Within one cell, there is only one type of DNA. However, there are three different types of RNA including:
  • mRNA (messenger RNA) carries messages coded in DNA from the nucleus or nucleoid to the site of protein synthesis (ribosomes) in cytoplasm.
  • rRNA (ribosomal RNA) is found in the structure of ribosomes, together with ribosomal proteins.
  • tRNA (transfer RNA) transfers the amino acids from cytoplasm to the ribosomes according to the order of three nitrogenous bases (a codon) in mRNA.

• DNA can be damaged due to overexposure to UV rays while RNA is comparatively resistant

DNA and RNA are both nucleic acids, meaning that they are both macromolecules (large molecules) that are responsible for storing and transmitting the genetic material of living organisms. ...

Answer 4

RNA is single stranded

DNA is a double helix

RNA contains cytosine, guanine, adenine, and uracil

DNA contains cytosine, guanine, adenine, and thymine

RNA processes the information that the DNA has stored to direct protein synthesis

DNA is the storage center of information

i hope this helped !
Well, DNA makes proteins and RNA delivers the proteins, DNA is double stranded and RNA is only single stranded, and The code things for DNA and RNA are different like AUGCT but i frogot exactly those

Answer 5

DNA is a doubled stranded structure, while RNA is a single stranded structure. RNA contains the sugar ribose, while DNA contains the sugar deoxyribose. RNA can have 4 nucleotides: cytosine, guanine, uracil, and adenine. DNA can have all these nucleotides except for uracil, which is replaced by thymine.

Answer 6

# Number of strands # The sugar # One of the bases In nature, RNA usually has one strand, DNA two. There are exceptions in viruses. Also, single-stranded DNA can be synthesized in laboratories for use e.g. as primers and probes.

Both nucleic acids have a pentose. In RNA it is ribose, in DNA deoxyribose.

RNA has uracil where DNA has thymine.

Another difference is speculative: many scientists believe RNA preceded DNA in the history of living organisms. Among other pieces of evidence is the fact that the distinctive components of DNA (thymine and deoxyribose) are synthesized in cells via the RNA equivalent: thymine by methylation of uracil, and deoxyribose by reduction of ribose.
i do not know....................

Answer 7

1. RNA has the uracil base instead of the thymine base.

2. RNA can move in and out of the nucleus, DNA can't.

3. There are many types of RNA in humans, DNA is always a double helix in humans.

4. RNA has an oxygen in its structure that DNA is lacking. Hence DNA's name Deoxyribonucleic acid.

Answer 8

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogen bases adenine, guanine, cytosine, and thymine, while RNA contains the nitrogen bases adenine, guanine, cytosine, and uracil. DNA is double-stranded, while RNA is single-stranded.

Answer 9

1. RNA is single stranded, DNA is double.

2. In RNA a bonds with u instead of t like in DNA

that's all i know =)

Answer 10

DNA is double helix, rna is one helix. DNA has a thymine rna has uracil. Rna has onxygen, DNA does not.
