1.2E Nucleic acids

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Term
Definition
adenosine triphosphate   ATP high-energy molecules used by the cell to synthesize macromolecules, such as carbohydrates and proteins  
🗑
complementary base pairing   the formation of weak hydrogen bonds between nitrogen-containing bases; T always pairs with A, C with G  
🗑
cytosine   nitrogenous base in RNA and DNA. bonds with guanine  
🗑
deoxyribonucleic acid DNA   twister ladder codes for the order in which amino acids join to form a protein; sugars and phosphates form a linear sugar-phosphate-sugar backbone, and the bases project from the sides of the backbone. adenine A + T thymine guanine G + C cytosine  
🗑
double helix   twisted ladder structure of DNA  
🗑
guanine   nitrogenous base in RNA and DNA. bonds with cytosine  
🗑
ribonucleic acid RNA   conveys DNA's instructions for the amino acid sequence in a protein  
🗑
nitrogenous base   an alkaline containing nitrogen A adenine, G guanine, C cytosine, T thymine  
🗑
nucleic acids   DNA and RNA, both polymers of nucleotides  
🗑
nucleotide   ATP 3 parts: phosphate group, pentose sugar (ribose), nitrogen-containing base  
🗑
phosphate    
🗑
thymine (T)   nitrogenous base in DNA. bonds with adenine  
🗑
uracil (U)   nitrogenous base in RNA. bonds with adenine  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
