Q2

Question 1

Genetic code

Answer 1

64 triplets of nucleotides. These triplets are called codons.

Question 2

Universal Genetic Code

Answer 2

The genetic code is universal because all species use the same four bases A,T,C and G, and each base sequence codes for the same amino acid in all species

Question 3

Degenerate Genetic code

Answer 3

The genetic code is described as degenerate, or redundant, because a single amino acid may be coded for by more than one codon.

Question 4

Transcription

Answer 4

Transcription is the process of making messenger RNA from a DNA template. DNA helicase breaks the hydrogen bonds between the DNA helix, free RNA nucleotides base pair with the exposed DNA template strand

Question 5

Splicing

Answer 5

Splicing is a process where pre mRNA is transformed into mRNA. It involves the removal of Introns ( gene sequences which do not code for proteins ) and the attachment of exons (sequences which code for proteins) together.
