10 Questions
DNA is single-stranded in structure.
False
DNA contains the nitrogenous bases G-C-A-U.
False
The backbone of DNA consists of phosphate and ribose sugar.
False
Gene expression involves only the process of translation.
False
During DNA replication, RNA primers provide the initiation sequence for RNA replication.
False
During DNA replication, the lagging strand is synthesized continuously.
False
DNA ligase is responsible for unwinding the DNA double helix during replication.
False
In transcription, RNA polymerase reads the mRNA strand and builds the DNA sequence.
False
The genetic code includes a total of 20 codons.
False
Translation begins with the mRNA binding to the large ribosomal subunit upstream of the start codon.
False
Learn about the molecular structure of DNA, RNA, and proteins, the genetic material that determines your characteristics and the instructions for making proteins in your cells. Explore the composition of DNA, including nucleotides made up of phosphate, deoxyribose sugar, and nitrogenous bases like G-C-A-T.
