Nucleotides are made up of 3 parts: ​ (a)   (such as ​ (b)   ) and the backbone made up of ​ (c)  

• bases
• adenine, thymine, guanine, cytosine
• phosphate and sugar

rRNA and proteins make up these structures in the cell

• ribosomes

• amino acids

• nucleoli

• vacuoles

​ (a)   used x-ray crystallography to idenitify the shape of DNA. ​ (b)   used this information to create a model of DNA as a double helix.

• Rosalind Franklin
• Watson & Crick

On DNA, these two bases are pyrimidines (and have a single ring): ​ (a)   . On DNA, these two bases are purines (and have a double ring): ​ (b)   .

• thymine and cytosine
• adenine and guanine

DNA is made up of a ​ (a)   strand and has the sugar ​ (b)   . RNA is made up of a ​ (c)   strand and has the sugar ​ (d)   .

• double

Messenger RNA (mRNA) is formed in the process of ____. DNA serves as the templae for making mRNA, which leaves the nucleus and travels to the ribosomes. It occurs in the nucleus of the cell.

• transcription

• replication

• translation

• mutation

Answer explanation

Replication - making duplicate DNA strands

Transcription - making mRNA from DNA

Translation - protein synthesis, using mRNA, tRNA, and rRNA
