Section 3

QuestionAnswer
Name the three main differences between DNA and RNA the sugar in RNA is ribose rather that deoxyribose, RNA is generally single stranded, RNA contains uracil in place of thymine
the assembly of amino acids into proteins is controlled by _______ RNA
name the three main types of RNA messenger, ribosomal, transfer
RNA molecules that carry copies of instructions for assembling amino acids into proteins are ________ messenger RNA (mRNA)
located in ribosomes and serves to assist transcription of mRNA ribosomal RNA (rRNA)
type of RNA molecule that transfers each amino acid to the ribosome as it is specified by coded messages in mRNA transfer RNA (tRNA)
process where RNA molecules are produced by copying part of the nucleotide sequence of DNA into a complementary sequence in RNA Transcription
During _________, RNA polymerase binds to DNA and separates the DNA strands. RNA polymerase then uses one strand of DNA as a template from which ________ are assembled into a strand of RNA transcription, nucleotides
regions of DNA which have specific base sequence, signals in DNA that indicate to the enzyme where to bind to make RNA promoters
large pieces removed from the RNA molecules transcribed from many eukaryotic genes before they become functional introns
remaining portions of RNA when they are spliced back together exons
consists of three consecutive nucleotides that specify a single amino acid that is to be added to the polypeptide codon
the decoding of an mRNA message into a polypeptide chain(protein) is known as what? translation
translation takes place on what organelle? ribosomes
during _______ the cell uses information form messenger RNA to produce proteins translation

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.
