A portion of DNA reads GAG. The corresponding mRNA would be

• GUG

• GTG

• CTC

• CUC

A portion of mRNA is coded CUG. The corresponding DNA is coded

• GAC
• GTC
• CTG
• CAG

The process of creating mRNA using DNA as the template is

• translation

• transcription

• translocation

In RNA, uracil takes the place of the DNA nitrogen base called

• guanine
• cytosine
• thymine
• adenine

The process shown in this image

• results in a new copy of the DNA
• does not happen during mitosis
• All of these apply
