DNA, RNA, and Protein Synthesis

DNA stands for ​_​ (a)   ​ (b)  

• deoxyribonucleic
• acid
• deoxyribose
• phosphate
• sugar

Match the following

• Adenine

• Adenine

• Uracil

• Guanine

• Cytosine

• Thymine

Nitrogen bases attach to the ​ (a)   , and the bases attach with ​ (b)  

• deoxyribose
• hydrogen bonds
• phosphate
• sugar ribose
• carbon bonds

True or False: Watson and Crick's first DNA model was inaccurate

• true

• false

Watson used ​ (a)   of DNA, containing ​​ (b)   and ​ (c)   when he discovered the structure of DNA (hint: for the "containing" part, put the answers in reverse alphabetical order)

• cardboard models
• pyrimidines
• purines
• metal model
• sushi

DNA Replication is ​ (a)   ; there will be one parent strand and one ​ (b)   strand

• semi-conservative
• daughter
• democratic
• conservaite
• conservative
• political

This type of genetic material is single-stranded

What are the three differences between DNA and RNA?

• RNA is triple-stranded

• RNA uses sugar ribose over deoxyribose

• RNA uses uracil over thymine

• DNA uses cytosine over uracil

• RNA is single stranded

First, which enzyme combines nucleotides to a promoter/start location in the DNA, breaking hydrogen bonds, allowing RNA nucleotides to pair up?

• x-ray polymerase

• RNA polymerase

• helicase

• DNA polymerase

Do the hydrogen bonds reconnect after transcription?

• yes

• no
