DNA Study Stack

QuestionAnswer
What does DNA stand for? Deoxyribonucleic Acid
What does DNA contain? Contains information to make proteins as well as the characteristics of organisms
True or False: DNA makes up the genes in chromosomes? True
What is a nucleotide? It is a repeating subunit of DNA
What are the 3 components of a nucleotide? 1) 5 carbon sugar (Deoxyribose) 2) Phosphate Group 3) Nitrogen base
Name the 4 nitrogen bases..... Adenine, Guanine, Cytosine, Thymine
Which other nitrogen base pairs with Adenine? Thymine - Remember the word "AT"
Which other nitrogen base pairs with Guanine? Cytosine - Remember C and G are close together in the alphabet
What shape is DNA? Double helix or a twisted ladder
What is each side of the DNA ladder made of? Repeating nucleotides
What holds the nucleotides together? Hydrogen bonds
What makes nucleotides different from each other? The different bases in each nucleotide make them different
Who used X-Rays to show the shape of the double helix? Rosalind Franklin
Who concluded that DNA twisted in a double helix and predicted how DNA is copied? Watson and Crick
What do proteins build? Cells, tissues and work as enzymes
Amino acids make up ___________? Proteins
What happens to a protein if the sequence of bases in DNA is replicated in the wrong order? The wrong protein may be made
When this DNA strand replicates, what will be the DNA sequence for the new strand? CCGTAACAGT GGCATTGTCA
This is half of a DNA strand. What would the mRNA be? GCGATGCAATG CGCUACGUUAC
What is thymine replaced with in RNA? Uracil
How many steps are in the DNA replication process? Four
In the following mRNA strand, what bases would pair with these? UACGGCUGA AUGCCGACU
True or False: Repeating units of DNA are called a double helix. True
True or False: If a sequence of DNA bases is made in the WRONG order, the RIGHT type of RNA will be made. False
Which of the 4 steps in the DNA replication process is this: An enzyme breaks apart the hydrogen bonds between each side of the DNA ladder. There are now two sides of the ladder exposed. Step 1
Which of the 4 steps in the DNA replication process is this: Free Floating nucleotides pair up with complementary bases. Step 2
Which of the 4 steps in the DNA replication process is this: A hydrogen bond forms between the complementary bases in the nucleotides. Step 3
Which of the 4 steps in the DNA replication process is this: Two new complete strands of DNA are formed. Step 4

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
