Vocab from the unit on DNA

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

Question/Term
Answer/Definition
The shape of DNA   Double Helix  
🗑
Adenine pairs with....   Thymine pairs with... (DNA only)  
🗑
Cytosine pairs with...   Guanine pairs with...  
🗑
Building blocks of DNA/RNA   Nucleotide  
🗑
Adenine pairs with (only in RNA)...   Uracil pairs with (only in RNA)...  
🗑
Building blocks of proteins   Amino Acids  
🗑
Types of bonds that hold DNA together   Hydrogen bonds  
🗑
Three parts of a nucleotide   Phosphate, sugar, and nitrogen base  
🗑
Chargaff's Base-Pairing Rules   A always pairs with T (always same amount of A and T) G always pairs with C (always same amount of G and C)  
🗑
What makes up the backbone/sides of DNA?   Phosphate and Sugar  
🗑
What makes up the rungs/steps of DNA ladder?   Nitrogen Bases A, T, G, C  
🗑
Differences between DNA and RNA?   DNA is double stranded, RNA single strand DNA has thymine, RNA has uracil DNA has deoxyribose, RNA ribose sugar  
🗑
mRNA   Messenger RNA that copies gene on DNA and brings message from nucleus to ribosome  
🗑
tRNA   transfer RNA that brings amino acids to ribosome for protein synthesis  
🗑
rRNA   ribosomal RNA- substance that makes up ribosomes along with proteins  
🗑
codon   3 letter sequence on mRNA that codes for amino acid  
🗑
anti-codon   3 letter sequence on tRNA that matches up with codon on mRNA  
🗑
ribosome   the location of protein synthesis  
🗑
transcription   copying code on DNA to mRNA in the NUCLEUS  
🗑
translation   using the mRNA to code for specific protein AT the RIBOSOME  
🗑
Mutation   Mistake in the DNA code  
🗑
Selective Breeding   Form of artificial selection where humans choose traits they want to see in an organism  
🗑
DNA fingerprinting   Form of DNA technology where specific DNA points on several organisms of the same species are mapped to look for similarities (used often in criminal investigations to compare crime scene DNA with suspect DNA)  
🗑
Polymerase Chain Reaction   DNA technology that makes millions of copies of a segment of DNA in order to study them in greater detail.  
🗑
Human Genome Project   Collaboration of many scientists worldwide to sequence the entire human DNA code Could help identify and cure diseases  
🗑
DNA Replication   The copying of DNA before cell division (mitosis or meiosis). Occurs in "S" of interphase.  
🗑
CRISPR   A technology used to edit genes in DNA within the cell. Basically, CRISPR finds specific genes, cuts them, and introduces mutations that can change the effect of the gene.  
🗑
Enzyme that unzips DNA before replication   Helicase  
🗑
Enzyme that builds new DNA strand   DNA Polymerase  
🗑


   

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.
