NGSS.HS-LS1-1

Match each to its function

• "unzips" DNA

• Helicase

• matches mRNA codon with its amino acid

• RNA primase

• Joins Okazaki fragments

• tRNA

• Synthesizes short RNA primers

• DNA ligase

In eukaryotes, where does transcription occur?

• Cytoplasm

• Nucleus

• Ribosome

• Mitochondria

Select all that are true

• DNA has Thymine (T) while RNA has Uracil (U)

• Both DNA and RNA travel outside of the nucleus

• DNA has a 5' and 3' end while RNA is directionless

• DNA is double stranded while RNA is single stranded

You are given the direction that RNA Polymerase is moving (left to right). Given this, fill each blank with either 5' or 3' to label the directionality of the mRNA strand being made and the two DNA strands.

Transcription of the sequence TTAAG produces which sequence?

• TTAAG

• UUAAG

• AAUUC

• AATTC

Replicate TCG GCA ATC

• AGC CGT TAG

• AGC CGU UAG

• AGC CGA ATC

• CTC CGA GAA

NGSS.HS-LS1-1

Explain how a mutation in the promoter region of a gene could impact transcription and ultimately protein synthesis.

Tags

NGSS.HS-LS3-2

The codon CGG experiences a single-point mutation that changes it to CGA. Identify whether the function of the protein would be affected and justify your answer.
