1. a+ --> a- mutation (forward mutation)
a > a+ reverse mutation (reversion)

2. Presence of pink pigment + / -
Four-o’clock plants
Incomplete dominance the term used to describe the general case in which the phenotype of a heterozygote is intermediate between those of the two homozygotes, on some quantitative scale of measurement

3. Point mutations at the molecular level

11. Now, insertions and deletions of base pairs:

14. Intragenic suppressor
Equivalent reversion
UCC (Ser) forward UGC (Cys) reverse AGC (Ser)
Wild type Mutant Wild type
CGC (Arg, basic) forward CCC (Proline) reverse CAC (His, basic)
Wild type Mutant Pseudo-wild type

15. Intragenic suppressor

16. Intergenic suppressor

17. Intergenic suppressor
Nonsense
suppressor

20. Regulatory
Coding

24. A situation in which the third nucleotide
WOBBLE
A situation in which the third nucleotide
of an anticodon (at the 5’ end) can form two alignments.
This third nucleotide can form hydrogen bonds not only with its
normal complementary nucleotide in the third position but
also with different nucleotide in the position.

25. I stands for inosine, one of the rare bases found in tRNA, often in anticodon

27. The genetic code is said to be degenerate because in many cases
MESSAGE
The genetic code is said to be degenerate because in many cases
more then one codon is assigned to a single amino acid, and, in addition,
several codons can pair with more then one anticodon (wobble)
