The structure of RNA differs from DNA in that?
the backbone of RNA contains ribose.
Differences of DNA and RNa on there jobs and structure?
Differences include that RNA uses ribose as a sugar and DNA uses deoxyribose, and DNA uses the base thymine while RNA uses uracil.
What is the major difference between normal DNA double helix and RNA double helix?
The term double helix refers to the structure formed by double-stranded molecules of nucleic acids. Only DNA forms a double helix because RNA is only single-stranded.
How do DNA and RNA work together?
DNA and RNA are two different nucleic acids found in the cells of every living organism. Both have significant roles to play in cell biology. DNA and RNA structure are similar because they both consist of long chains of nucleotide units. However, there are a few structural details that distinguish them from each other, and if you are to compare DNA and RNA, these would be the results: RNA is single-stranded while DNA is a double-stranded helix. RNA also has uracil as its base while the DNA base is thymine. However, even with the differences in their structures, DNA and RNA have cooperating roles in the field of Cell Biology. DNA contains the genetic information of an organism, and this information dictates how the body's cells would construct new proteins according to the genetic code of the organism. Within the cell structure, DNA is organized into structures called chromosomes, which are duplicated during cell division. These chromosomes would then release the genetic codes that will be transcribed and carried by the RNA (specifically the messenger RNA) to the ribosome. The ribosome will then synthesize new proteins that will help the body grow. This is the how the DNA and RNA work together in the body.
What are two ways in which RNA structure differs from DNA structure?
Chemically RNA and DNA only differ by a single oxygen atom in each nucleotide. Specifically the sugar group in an RNA nucleotide is the sugar ribose, wherease the sugar group in DNA is deoxyribose. Wikipedia has a nice image showing this here: http://en.wikipedia.org/wiki/File:Nucleotides_1.svg Structurally RNA and DNA are also different. DNA exists almost exclusively in a double stranded helix. RNA is typically thought of a single chain that has a far more chaotic structure with the RNA folding back onto itself creating small helical regions where possible. DNA nucleotides contain a different sugar than RNA nucleotides.
What is a similar structure of DNA?
RNA
Structure of tRNA different from DNA?
RNA makes up DNA. RNA makes up DNA. tRNA is a structure of DNA.
What sugar does in DNA and RNA?
Ribose in RNA and deoxyribose in DNA. They are quite similar.
What is a description of the structure of DNA and RNA?
DNA is double stranded whereas RNA is single stranded . They are different in their functioning as well .
What base is not found in the structure of DNA?
The base "uracil" is not found in the structure of DNA, but rather in RNA, as uracil replaces thymine in RNA.
How does the double helix structure of RNA resemble the structure of DNA?
First of all, RNA is a single helix. It isn't really similar to the DNA in the obvious shape. In DNA there two long polynucleotides chins which are right handed double helix. the chains are antiparallel to each other. while in RNA there is only a single chain.
The structure of RNA differs from DNA in that?
the backbone of RNA contains ribose.
Is a phosphate DNA or RNA?
Both DNA and RNA contain a sugar phosphate group as the backbone to their structure. In DNA the sugar is deoxyribose, where as in RNA it is just ribose.
A major difference in RNA as compared to DNA is the presence of the sugar?
DNA and RNA are similar compounds with a few differences. In DNA, the sugar is deoxyribose; in RNA, it is ribose.
Is virus a structure?
Yes. It is either DNA or RNA.
What biomolecule codes for the structure of a cell?
Rna dna
Name the 3-part structure that makes up both DNA and RNA?
pentose(ribose for RNA; deoxyribose for DNA), nitrogen base(AUGC for RNA; ATGC for DNA) and phosphate.
