THEORETICAL QUESTIONS NECESSARY FOR ACHIEVING of the PRACTICAL CLASSES

ORGANIZATIONAL STRUCTURE of the PRACTICAL STUDY

1. Variation as a biological phenomenon. Classification of variation. Sources of phenotype variation.

2. New combination of genes.

3. Mutations. Classification of mutations. Modifications and aberrations of chromosomes.

4. Modifications of genes (genes mutations).

5. Causes of mutation.

6. Mechanisms of defense against mutations.

To acquisition of practical skills of using the genetic laws solve tasks.

1. The sequence of nucleotides in the part of DNA molecule is ACAATAGTAAAAGAA. What changes are within protein, if

a) Change the third nucleotide to G,

b) Change the fourth nucleotide to C,

c) Delete the fifth nucleotide,

d) Add the T between the 11-th and 12-th nucleotides.

2. The fourth nucleotide in normal hemoglobin (peptide) has the sequence of amino acids val-gys-ley-tre-pro-glu-lis. Define the character of mutation, if the abnormal peptide is val-gys-ley-tre-pro-lis-glu-lis.

3. Is it transition or transversion?

a) normal triplet GAA, abnormal triplet GTA

b) normal triplet GAA, abnormal triplet AAA

c) normal triplet GAA, abnormal triplet CAA

4. Build the variational series and variational graph of pulse frequency of students. Define the simple average of this characteristic.
