CC Transcription - DNA to mRNA CC Cooper

What do the strands of DNA code for?

• computer programs

• many different proteins

What is the first step of protein synthesis?

• transcription

• translation

In Transcription a strand of _____ is made from the DNA template.

• mRNA

• rRNA

• tRNA

A "C" nucleotide will match up with a _____

• "T" nucleotide

• "G" nucleotide

•  "U" nucleotide

When the DNA contains an "A" nucleotide then the mRNA will have ______ because mRNA uses URACIL (U) instead of THYMINE (T).

• a "U" nucleotide.

• a "G" nucleotide.

In mRNA, what matches with "A"?

• "C"

• "G"

• "U"

• "T"

What is the correct mRNA strand for this DNA template?

Where is the mRNA transcribed from DNA?

• in the cytoplasm

• in the nucleus

• at a ribosome

What is the purpose of mRNA?

• To make DNA.

• To carry the DNA code out of the nucleus without DNA leaving the nucleus.

mRNA will go to a _____ in the cytoplasm where protein is made.

• nuclear membrane

• ribosome
