How does the structure of RNA differ than DNA?

Answer 1

In protein formation, mRNA carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). Ribosomes are composed of rRNA and protein; they can "read" the code carried by the mRNA. A sequence of three nitrogenous bases in mRNA specifies incorporation of an amino acid; tRNA brings the amino acids to the ribosomes, where they are linked into proteins.

Answer 2

1. RNA has a ribose sugar group. DNA's sugar group has one fewer oxygen, hence deoxyribose.

2. Within your cells, RNA is typically single-stranded. DNA is double-stranded.

3. Within your cells, RNA typically has Uracil where DNA would have Thymine.

4. Um, I don't know. I can't think of any more! Um... how about... DNA strands are longer? or DNA strands are supercoiled and RNA isn't?

Answer 3

DNA double-strands into the famous double helix shape. RNA, however, is only 1 strand. As well, the bonding sugars in DNA and RNA are different, the 'deoxyribose' vs 'ribose' of the full names of these molecules. DNA also simply serves as a set of directions which the RNA reads and then helps carry out.

Answer 4

RNA is typically single-stranded, while DNA is double-stranded. RNA contains ribose sugar and uracil as one of its bases instead of deoxyribose sugar and thymine found in DNA. RNA molecules are usually shorter than DNA molecules.

Answer 5

The sugar is only ribose in RNA, deoxyribose on DNA, RNA has uracil instead if thymine as a base, and RNA is single stranded while DNA is double, also, look up the different types
