DNA and proteins

DNA is made up of repeating units called?

• nucleus
• nucelotomes
• nucleotides
• RNA

What bases would be connected to the other DNA nucleotide? (read carefully)

• Thymine-Adenine
  Adenine-Thymine
  Guanine-Cytosine
  
• Thymine-Guanine
  Adenine-Thymine
  Guanine-Cytosine
• Thymine-Adenine
  Adenine-Thymine
  Guanine-Adenine

If one DNA strand has a code GATTA then its complementary strand will have the code:

• ATAAT
• CTAGT
• CTAAT
• CTATT

The triplet code in DNA such as "GAT" codes for...

• RNA
• Amino Acids
• Proteins
• Additional DNA

RNA has two main differences when compared to DNA apart from its helix structure is...

• Sugar is ribose and has uracil instead of thymine
• Sugar is ribose and has uracil instead of adenine
• Sugar is deoxyribose and has adinine instead of thymine

Which enzyme pairs nucleotides together during replication and also "proofreads" the new DNA strand and corrects any mistakes?

• DNA polymerase
• Ligase
• Helicase
• Primase

What is the purpose of DNA Replication?

• ensures that every cell has exactly half of the DNA as original
• assures that every cell has a complete set of identical genetic information
• ensures each cell has twice as much DNA as the original
• ensures that your offspring will look just like you

Base pairs in a DNA strand are held together by what type of bonds?

• covalent
• hydrogen
• ionic
• James

Where does transcription take place?

• nucleus
• cytoplasm
• ribosome
