DNA structure

QuestionAnswer
What are the three parts of a nucleotide? sugar, phosphate, and a nitrogen base
What are the initials of the four nitrogen bases in DNA? A, C, G, T
What is the full name of DNA? deoxyribonucleic acid
DNA wraps around proteins to package into now being called a _______. become a chromosome
What base bonds with C? G
What base bonds with T? A
What type of bond holds the bases together in the DNA strand to form a double strand? hydrogen bond (easy to unzip)
What two parts of the nucleotide form covalent bonds with the next nucleotides to make up the backbone of the DNA molecule? Sugar, phosphate
What is made from DNA? RNA
What is made using RNA? proteins
What part of the nucleotide is variable? nitrogen base (therefore it is the information)
What is the shape of the DNA molecule? double helix
What is a change in the DNA sequence called? mutation
When one says DNA sequence, it is referring to the sequence or order of _________. nitrogen bases/ nucleotides
What does the double in "double helix" mean? 2 strands of DNA nuclotides weakly held together with hydrogen bonds.
What part of the backbone does the nitrogen base bond to? sugar
How many nucleotides are in your nuclei? 3,000,000,000 or 3 x 10^9
What part of a nucleotide is different from nuclotide to nucleotide in DNA nitrogen base Four different ones: A, T, C, G,
When a mutation happens, what is not properly made? protein; different DNA makes a nonfunctional protein.
Would a mutation in an egg cell or a heart cell be more damaging? Typically an egg as all resulting cells of the organism when it is fertilized would have the mutation, where it would just be one cell in the heart that has millions.

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.
