Non coding DNA

Question 1

The genome within eukaryotic cells contains many non-coding sections of DNA
Non-coding DNA does not code for any amino acids

Non-coding DNA can be found between

Answer 1

genes, as non-coding multiple repeats
This means they contain the same base sequences repeated multiple times

Question 2

Non-coding DNA can also be found within genes, as

Answer 2

introns
The coding exons can be separated by one or more introns

Question 3

During transcription, eukaryotic cells transcribe the whole gene (all introns and exons) to produce

Answer 3

pre-mRNA molecules

Question 4

Before the pre-mRNA exits the nucleus the ………… are removed and the coding sections (exons) are joined together in a process called splicing

Answer 4

non-coding sections (introns

Question 5

What is splicing

Answer 5

coding sections (exons) are joined together in a process called splicing

Question 6

he RNA molecule produced from the transcription of a gene contains introns that must be removed before ………… occurs

Answer 6

translation
