REPLICATION OF DNA

20 QUESTIONS

QuestionAnswer
3 PROCESSES THAT MUST OCCUR FOR THE PROTEINS TO BE MADE CORRECTLY- DNA REPLICATION, TRANSCRIPTION, AND TRANSLATION
THE SHAPE OF A DNA MOLECULE IS USUALLY DESCRIBED AS A- DOUBLE HELIX
(TRUE OR FALSE) THE SEQUENCE OF THE NUCLEOTIDES IS CHANGED. FALSE
WHAT WOULD BE THE DNA COMPLEMENT TO THE SECTION OF DNA =GCCTTA= CGGAAT
DNA CONTAINS GENETIC INFORMATION IN ITS- NUCLEOTIDE SEQUENCE
(TRUE OR FALSE) CHROMOSOMES ARE MADE UP OF RNA AND PROTEIN. GENES ARE not SECTIONS OF DNA ON A CHROMOSOME. FALSE
WHY ARE PROTEINS IMPORTANT? THE CELL'S PROTEINS CONTROL ALL OF THE PROCESSES IN THAT CELL
WHAT ARE THE 3 PARTS OF NUCLEOTIDES? A SUGAR, A PHOSPHATE GROUP, AND A NITROGEN BASE
WHAT ARE THE FOUR BASES OF DNA? ADENINE, GUANINE, THYMINE, CYTOSINE
WHAT IS THE SUGAR IN DNA CALLED? DEOXYRIBOSE
WHO ARE THE 2 SCIENTISTS THAT DISCOVERED THE TWO CHAINS OF NUCLEOTIDES? CRICK AND WATSON
THE TWO CHAINS ARE JOINED TOGETHER AT THE NITROGEN BASES BY- HYDROGEN BONDS
WATSON AND CRICK ALSO DISCOVERED THAT THE DNA IS TWISTED IN A SHAPE CALLED A- DOUBLE HELIX
WHAT MAKES UP THE "RUNGS" OF THE DOUBLE HELIX "LADDER" STRUCTURE? THE COMPLEMENTARY BASE PAIRS
WHY IS THE SEQUENCE OF THE NUCLEOTIDES VERY IMPORTANT? NUCLEOTIDE SEQUENCES FORM THE GENETIC INFORMATION OF EVERY ORGANISM
(TRUE OR FALSE) IF A NUCLEOTIDE SEQUENCE CHANGES, THEN THE INFORMATION THAT IT CARRIES WILL STAY THE SAME. FALSE
(TRUE OR FALSE) CHROMOSOMES ARE MADE OF DNA AND PROTEIN. TRUE
WHAT ARE THE SECTIONS OF DNA THAT PROVIDE INFORMATION ABOUT SPECIFIC TRAITS? GENES
WHAT IS THE FIRST STEP OF DNA REPLICATION? THE TWO STRANDS OF DNA UNZIP. THE HYDROGEN BONDS ARE BROKEN AND THE NITROGEN BASES ARE EXPOSED.
DURING DNA REPLICATION, A SECTION OF THE DNA HAS A NUCLEOTIDE SEQUENCE OF A-T-T-G-C-C. WHAT WOULD BE THE SEQUENCE OF NUCLEOTIDES THAT FORMS THE COMPLEMENT TO THIS SECTION OF DNA? T-A-A-C-G-G

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.
