PROTEIN SYNTHESIS

QuestionAnswer
Protein synthesis takes 2 steps: transcription & translation
DNA to RNA transcription
RNA to DNA translation
TRANSCRIPTION purpose Carry the code/instructions out of the nucleus
Transcription location nucleus
Transcription starts with DNA
Transcription ends with mRNA
Three Essential Types of RNA mRNA (messenger), tRNA (transfer), and rRNA (ribosomal)
DNA sequence (template): TACGCTAGTACGATT mRNA sequence: AUGCGAUCAUGCUAA
Genetic Code code of instructions for how to make proteins
Codon a set of 3 nucleotides on the mRNA
Anticodon complementary” 3 nucleotides on tRNA
TRANSLATION Purpose Read/follow the instructions carried on the mRNA to make a protein
Translation location Cytoplasm / Ribosome
Translation starts with mRNA (translation)
Translation ends with protein (translation)
The ribosome releases the completed protein. When the “stop codon” is reached
Amino acids are bonded together with peptide bonds
Purines are Adenine and Guanine
Pyrimidine are cytosine, Thymine and Uracil
Helicase Unzips the DNA during replication
DNA polymerase Joins the nucleotides together in a DNA strand
Base pairing In DNA the ft between Thymine and Adenine and th fit between Cytosine and Guanine is called?

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.
