DNA and RNA
19 Oct 09
What are the differences between DNA and RNA?
-deoxyribonucleic acid
-double helix
-lacks oxygen in its ribose sugar
-its nitrogenous bases are adenine, thymine, cytosine, and guanine
-ribonucleic acid
-single stranded
-contains oxygen in its ribose sugar
-its nitrogenous bases are adenine, uracil, cytosine, and guanine
-uracil replaces thymine in RNA

Transcription/Translation
21 Sep 09
In genetics, what is the difference between transcription and translation?
Transcription refers to all the steps involved in the replication of DNA. Transcription uses one strand of the double stranded DNA as template for replication.
Translation is the process of producing a protein (polypeptide) from mRNA.
Therefore, transcription is the replication of DNA and translation is the synthesis of protein.
