Science 7 Unit 9

DNA-Genetic Coding and Protein Synthesis

QuestionAnswer
**DNA makes... chromosomes
Chromosomes have... genes
Genes code for... proteins
Proteins give us... our traits
The genetic material that carries information about an organism and is passed from parent to offspring DNA (Deoxyribonucleic Acid)
What is also known as an organism's genetic "blueprint?" DNA
DNA is usually found in the what of cells? nucleus
The shape of a DNA molecules in called... double helix
DNA is made up of smaller pieces called... nucleotides
Nucleotides are made up of... 1. Deoxyribose Sugar 2. Phosphate Group 3. Nitrogen Base Pairs
(BLANK) (A) pairs with (BLANK) (T) adenine (A) pairs with thymine (T)
(BLANK) (G) pairs with (BLANK) (C) guanine (G) pairs with cytosine (C)
Nitrogen base form (BLANK) of the DNA (BLANK) rungs ladder
The order of the (BLANK) along a gene forms a (BLANK) the specifies what type of a (BLANK) will be produced, nitrogen bases code amino acid
Amino acids are the building blocks that our made from what? proteins
Strand 1: T Strand 2: A
Strand 1: A Strand 2: T
Strand 1: G Strand 2: C
Strand 1: C Strand 2: G
Strand 1: Strand 2: T A
Strand 1: Strand 2: A T
Strand 1: Strand 2: C G
Strand 1: Strand 2: G C
TRUE OR FALSE? Adenine (A) pairs with thymine (T) True
TRUE OR FALSE? Thymine (T) pairs with adenine (A) True
TRUE OR FALSE? Guanine (G) pairs with cytosine (C) True
TRUE OR FALSE? Cytosine (C) pairs with guanine (G) True
TRUE OR FALSE? Adenine (A) pairs with cytosine (C) False
TRUE OR FALSE? Adenine (A) pairs with guanine (G) False
TRUE OR FALSE? Thymine (T) pairs with cytosine (C) False
TRUE OR FALSE? Thymine (T) pairs with cytosine (C) False
TRUE OR FALSE? Thymine (T) pairs with guanine (G) False
TRUE OR FALSE? Cytosine (C) pairs with adenine ((A) False
TRUE OR FALSE? Cytosine (C) pairs with thymine (T) False
TRUE OR FALSE? Guanine (G) pairs with adenine (A) False
TRUE OR FALSE? Guanine (G) pairs with thymine (T) False
Think about cell division, why do you think cells need to be replicated? Repair the body and growth of cells. To reproduce.
perform many different tasks in our bodies including giving us our physical traits Proteins
During protein synthesis a cell uses information from a (BLANK) to produce a (BLANK) that will express a (BLANK) During protein synthesis a cell uses information from a gene to produce a protein that will express a genetic trait.
DNA replication begins when... the double helix untwists
The DNA strand breaks apart between the nitrogen bases which is known as... "unzipping' the DNA
Next nitrogen bases pair with (BLANK) to form messenger RNA. Next nitrogen bases pair with their complementary base pair to form messenger RNA.
Copies a section of code from the DNA in the nucleus and carries these instruction the the ribosome Messenger RNA (mRNA)
When nitrogen bases pair with their complentary bases to form messenger RNA. *Thymine becomes a... Uraeil*
When mRNA enters the (BLANK) it still needs the blueprint (code) to create the correct protein. When mRNA enters the ribosome it still needs the blueprint (code) to create the correct protein.
What transfers that code into the correct protein? Transfer RNA
translates a codon (3 nitrogen bases) then gets the correct amino acid and codes it into a protein Transfer RNA (tRNA)
Proteins leave the ribosome to travel where? where they are needed in the body

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.
