Reorder the following steps of DNA Replication from start to finish.

• The original strand of DNA is in a double helix.

• Two strands of identical DNA are made.

• An enzyme breaks the hydrogen bonds between the two nucleic acid strands.

• The two nucleic acid strands separate from each other.

• New nucleotides are put in place by DNA Polymerase according to the base-pairing rules.

What is the purpose of protein synthesis?

• to make a copy of DNA

• to transcribe DNA into messenger RNA

• to produce a protein from the info stored in DNA

• to translate mRNA into a protein

NGSS.HS-LS1-1

Match the following

• tRNA

• Made in the nucleus from DNA; makes a transcript of the gene being used

• mRNA

• carries amino acids to the ribosome

• rRNA

• Found inside and is part of the ribosome; helps to build the protein

What is the purpose of transcription in protein synthesis?

• To replicate DNA

• To carry amino acids to the ribosome

• To copy a segment of DNA into RNA

• To obtain the information on how to produce a ribosome

Reorder the following steps of Transcription in Protein Synthesis.

• The segment of DNA that needs to be expressed unwinds in the nucleus

• An enzyme will attach RNA nucleotides to the exposed bases

• Messenger RNA leaves the nucleus and heads to the ribosome

• Messenger RNA will be released and the DNA seals back up

• The whole gene is transcribed or copied

The purpose of translation in protein synthesis is

• To make amino acids that your body is unable to make.

• To use the information in mRNA to assemble a protein

• to use tRNA to make a copy of the DNA molecule

• to use DNA to help make tRNA
