Question 1

Gene

Answer 1

Section of DNA containing coded info for making polypeptides + functional RNA

Question 2

Genetic code (triplet)

Answer 2

Sequence of 3 bases that code for and amino acid (64 possible codes)

Question 3

Degenerate

Answer 3

Reference to fact that most amino acids are coded by more than one triplet (20 diff a.acids and 64 codes)

Question 4

Exons

Answer 4

Coding sequences within genes

Question 5

Introns

Answer 5

Non-coding sequences within genes that separate exons (in eukaryotes)

Question 6

Codon

Answer 6

Sequence of 3 bases in mRNA that code for single amino acid (complementary to a triplet in DNA)

Question 7

Anticodon

Answer 7

Sequence of 3 adjacent bases on molecule of tRNA that is complementary to particular codon on mRNA molecule

Question 8

RNA polymerase

Answer 8

Enzyme joins together nucleotides to form mRNA during transcription

Question 9

Transcription

Answer 9

Process where complementary section of DNA sequence is made into molecule of pre mRNA

Question 10

Translation

Answer 10

Process in which mRNA used as a template to which complementary tRNA molecules attach + a.acids they carry are linked to form a polypeptide
