Multiple Choice

What binds together to create proteins?

• Sugars

• Nucleotides

• Lipids

• Amino Acids

RNA

Single strand

Uracil instead of thymine

3 types

Multiple Choice

In RNA, what base replaces Thymine?

• Cytosine

• Guanine

Multiple Choice

Determine the RNA sequence that compliments the DNA stranded:

TACGGT

• TACGGT

• AUGCCA

• ATGCCA

• UACGGU

mRNA

• Messenger RNA

• made from DNA

• made in nucleus, flows to cytoplasm

rRNA

• Ribosomal RNA

• In cytoplasm

• Reads mRNA (codons)

Multiple Choice

How does rRNA read the mRNA strand?

Protein Synthesis

2 Stages; Transcription & Translation

Transcription

• Occurs in Nucleus

• mRNA produced from DNA

• mRNA leaves to cytoplasm

Multiple Choice

What is produced by transcription?

• mRNA

• rRNA

• tRNA

• DNA

Translation

• Occurs in cytoplasm at a ribosome

• rRNA attaches to mRNA

• rRNA reads mRNA (codons)

• tRNA brings amino acids

• Amino acids bind making proteins

Multiple Choice

Where does translation occur?

• In the cytoplasm

• At a ribosome

• In the cytoplasm at a ribosome

• In the nucleus

Multiple Choice

What is produced by translation?

• rRNA

• mRNA

• Proteins

• Lipids

Multiple Select

Which types of RNA are used in translation? Select all correct options

• DNA

• mRNA

• rRNA

• tRNA

Codons

• 3 nucleotides on mRNA

• rRNA reads codons

• 1 codon = 1 amino acid

• Combination of codons makes unique protein

• tRNA brings Amino acid based on codon

Multiple Choice

What is a codon?

• A set of 3 nucleotides on mRNA

• A set of 3 nucleotides on DNA

• A whole strand of mRNA

• An amino acid

Multiple Choice

What type of RNA is responsible for bringing amino acids?

• mRNA

• tRNA
