what are the 2 main differences in DNA and RNA?

Answer 1

The two main differences are:
Deoxyribose sugar in DNA, against ribose sugar in RNA.
Thymine base of DNA is replaced by uracil in RNA.
There are other differences in the secondary structure and functions of these two nucleic acids.

Answer 2

RNA 1-Formed of a single strand
2-Its ribose sugar instead of deoxyribose.
3-No thymine base, and the presence of uracil base instead.
These are the main differences there are other differences such as
-DNA is mostly found in the nucleus where it forms the principle substance of the chromosomal material. Little DNA found in mitochondria and in chloroplasts. Many viruses are made up of DNA double stranded but some are single stranded.Carrier of genetic information and has 2 important functions (replication and transcription).
-While RNA is found in the cytoplasm.Little RNA is also found in the nucleus, in the mitochondria and in chloroplasts.Some viruses are made up of RNA.Function is responsible for synthesis of all types of proteins in the cell.

Answer 3

DNA has the nitrogenous bases adenine,guanine,thymine,cytosine,but RNA has Uracil insteadof thymine.DNA takes part ion both cell division and protein synthesis,but RNA takes part only in protein synthesis.There is only one type of DNA, RNa are -Transport RNA,Ribosomal RNA,Messenger RNA.

Answer 4

a) DNA has the pentose sugar deoxyribose where RNA has the pentose sugar ribose.
b) DNA incorporates thymine where RNA incorporates Uracil.

Answer 5

DNA contains the bases adenine, thymine, guanine and cytosine.
RNA contain the bases adenine, uracil, guanine, and cytosine.

DNA is double stranded.
RNA is single stranded.
