bio2 test 1

DNA and RNA formation. Mutations.

QuestionAnswer
what is the shape of DNA? a double helix
what are the sides and backbones of DNA made of? nucleotides (sugars)
what are the 4 nitrogen bases? A-T, G-C
what is the shape of RNA? 1 single strand
what are the nitrogen bases involved in RNA? A-T, G-C
what is the sugar involved in RNA? ribose
where is RNA located? in the ribosomes
how many stands are in DNA? 2 strands
what is the sugar involved in DNA? deoxyribo
DNA base pairing? A-T, C-G
RNA base pairing? A-U, G-C
what are the steps to DNA replication? DNA unwinds, replication fork forms,DNA polymerse attaches to a new base.
what is the role of DNA polymerase? make DNA from nucleotides
what is made in DNA replication? new DNA for new cells
what is the order of protein synthesis? DNA -(transcription)-RNA-(translation)- protein
what are the steps to transcription? DNA unwinds, 1 strand is used as a template, RNA polymerse attaches to new base, mRNA goes to the ribosomes
what is does transcription make? a protein
what are the steps to translation? mRNA from transcription starts codon, RNA attches to mRNA,tRNA brings amino acids to anti codon, moves along
what is made in translation? protiens
who are the founders of the structure of DNA? Crick and Watson
what is the purpose of mRNA? sends messages to make a protein
what is the purpose of tRNA? transfers the amino acids
what is the purpose of rRNA? links amino acids to protiens
what is a codon? a sequence that make amino acids
how many bases are in a codon? 3

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.
