Unit 6 AP Biology Part 1

Front

What is the amino acid sequence produced from the mRNA codon sequence 5'-AUG-UCU-UCG-UUA-UCC-UUG-3'?

Back

met-ser-ser-leu-ser-leu

Front

Which molecule binds to the promoter region during transcription?

Back

RNA polymerase

Front

What is the term for the sequence of nucleotides on mRNA read in triplets?

Back

codon

Front

If a nucleic acid consists of 29% cytosine, 35% uracil, 10% adenine, and 26% guanine, what type of nucleic acid is it?

Back

single-stranded RNA

Front

What are the three main steps of translation?

Back

Codon recognition, peptide bond formation, translocation

Front

What is the role of RNA polymerase in transcription?

Back

RNA polymerase synthesizes RNA from a DNA template.

Front

Define a codon.

Back

A codon is a sequence of three nucleotides on mRNA that codes for a specific amino acid.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is the function of ligase in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand.

Front

What is the significance of the promoter region in gene expression?

Back

The promoter region is where RNA polymerase binds to initiate transcription.
