4 diferencias del ADN y RNA cada una similitudes ente los dos

DNA stands for deoxyribonucleic acid, while RNA is ribonucleic acid. Although DNA and RNA both carry genetic information, there are quite a few differences between them. This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences. Comparison of DNA and RNA

While both DNA and RNA are used to store genetic information, there are clear differences between them. This table summarizes the key points:Main Differences Between DNA and RNA

ComparisonDNARNA

NameDeoxyriboNucleic AcidRiboNucleic Acid

FunctionLong-term storage of genetic information; transmission of genetic information to make other cells and new organisms.Used to transfer the genetic code from the nucleus to the ribosomes to make proteins. RNA is used to transmit genetic information in some organisms and may have been the molecule used to store genetic blueprints in primitive organisms.

Structural FeaturesB-form double helix. DNA is a double-stranded molecule consisting of a long chain of nucleotides.A-form helix. RNA usually is a single-strand helix consisting of shorter chains of nucleotides.

Composition of Bases and Sugarsdeoxyribose sugar

phosphate backbone

adenine, guanine, cytosine, uracil bases

PropagationDNA is self-replicating.RNA is synthesized from DNA on an as-needed basis.

Base PairingAT (adenine-thymine)

GC (guanine-cytosine)AU (adenine-uracil)

GC (guanine-cytosine)

ReactivityThe C-H bonds in DNA make it fairly stable, plus the body destroys enzymes that would attack DNA. The small grooves in the helix also serve as protection, providing minimal space for enzymes to attach.The O-H bond in the ribose of RNA makes the molecule more reactive, compared with DNA. RNA is not stable under alkaline conditions, plus the large grooves in the molecule make it susceptible to enzyme attack. RNA is constantly produced, used, degraded, and recycled.

Ultraviolet DamageDNA is susceptible to UV damage.Compared with DNA, RNA is relatively resistant to UV damage.

Explanation: Summary of Differences Between DNA and RNA

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring.

DNA is a double-stranded molecule, while RNA is a single-stranded molecule.

DNA is stable under alkaline conditions, while RNA is not stable.

DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.

DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
