07-05b Protein Synthesis

Where can you find DNA in eukaryotes?

• in the nucleus

• in the cytoplasm

• on the ribosome

• in the nucleus and in the cytoplasm

What is the first part of protein synthesis?

• translation

• transcription

• replication

• cytokinesis

What is one difference between DNA and RNA?

• DNA is single-stranded and RNA is double-stranded

• DNA is in the cytoplasm and RNA is on the ribosomes

• RNA has uracil and DNA has thymine

• DNA has dexoyribose sugar and RNA has reoxyribose sugar

What matches up with adenine in RNA?

• thymine

• guanine

• uracil

• cytosine

What is the mRNA sequence for this DNA sequence?

ACT TTA GCA TAT AAG

(all caps + space between codons)

(a)  

What is the outcome of transcription?

• one single-stranded RNA

• two single-stranded RNA

• two double-stranded DNA

• one single-stranded DNA

What is the purpose of mRNA?

• it carries code of DNA bases used for protein synthesis

• it produces the enzymes needed to form peptide bonds

• it picks up amino acids in cytoplasm and brings to ribosome

• it carries the DNA into the cytoplasm

What is the purpose of tRNA?

• it carries the DNA into the cytoplasm

• it carries code of DNA bases used for protein synthesis

• it produces the enzymes needed to form peptide bonds

• it picks up amino acids in cytoplasm and brings to ribosome

What does the "r" in rRNA stand for?

•  rhinosomal

• radisomal

• ribosomal

• redosomal

What bond is broken during DNA replication and the transcription part of protein synthesis?

• peptide bond

• covalent bond

• hydrogen bond

• ionic bond
