DNA

Question 1

Transcription

Answer 1

The process of making a copy of genetic information in the form of mRNA

Question 2

mRNA

Answer 2

An enzyme that makes mRNA by joining bases together. It moves along the template strand of the DNA and forms mRNA molecule

Question 3

RNA polymerase

Answer 3

An enzyme that makes mRNA by joining bases together. It moves along the template strand of the DNA and forms an mRNA molecule

Question 4

Transcription (method)

Answer 4

1. RNA polymerase, an enzyme that can join RNA bases together, binds to a region of DNA just before the gene
2. The DNA strands unzip so that one strand can be used as a template
3. RNA polymerase moves along the DNA and uses the template strand to make mRNA by bringing in the complementary base and joining theses together in a single strand
4. Once the mRNA has been made, it will move out of the nucleus towards the ribosome
