Semester 2 - List #3

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

Question
Answer
Nucleotide   Monomer of nucleic acids; these bond together to make strands of DNA and RNA  
🗑
Protein   Carbon based molecule that does the work in a cell and is created by ribosomes that bond amino acids together  
🗑
Base Pairing Rules   Also known as Chargaff's Rules; states that in DNA, Adenine bonds to Thymine and Cytosine bonds with Guanine  
🗑
Replication   Process that occurs in the nucleus and creates 2 new strands of DNA  
🗑
DNA Polymerase   Enzyme that bonds nucleotide together during Replication  
🗑
Central Dogma   Theme of protein synthesis that states information can only flow in one direction; DNA to RNA to Protein  
🗑
DNA   Substance which makes up chromosomes as a double helix and carries instructions for which proteins need to be created  
🗑
mRNA   Substance which is single stranded and carries information from the nucleus to a ribosome with instructions to make a protein  
🗑
tRNA   Substance with is single stranded and brings amino acids to the ribosome to create a protein  
🗑
Transcription   Process that occurs in the nucleus and creates strands of RNA  
🗑
Translation   Process that occurs at a ribosome and results in the creation of a protein  
🗑
Codon   A section of mRNA which consists of 3 nucleotide bases which codes for a specific amino acid  
🗑
Amino Acid   Bonded together at a ribosome to make a protein  
🗑
Frameshift Mutation   Insertion or deletion of a nucleotide which results in errors in mRNA and a change to the needed protein  
🗑
Point Mutation   Substitution of a nucleotide base which results in errors in mRNA and a change to the needed protein  
🗑
Mutagens   Substances in the environment which can change DNA in a cell and results in mutations of proteins  
🗑


   

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.
