THEORETICAL QUESTIONS NECESSARY FOR ACHIEVING of the PRACTICAL CLASSES

ORGANIZATIONAL STRUCTURE of the PRACTICAL STUDY

1. Nucleic acids as the polymers of nucleotides. Types of nucleic acids.

2. Structure and functions of DNA.

3. Characteristic and significance of DNA replication.

4. Types, structure, and functions of RNA.

5. Characteristic and significance of RNA synthesis.

6. Definition and property of gene.

7. Classification of genes.

8. Definition and property of genetical code.

9. Genes' expression. Biosynthesis of protein.

10. Significance of genes' expression regulation. Model of operon.

11. Particularities of eukaryotes' genes expression regulation.

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

1. Define what is heavier: or protein or coding gene?

2. Define length and mass of the gene, which code the protein with molecular mass 3.200 Dalton.

3. How many aminoacids will have polypeptide, if molecula of mRNA has mass 20.000 Dalton?

4. Gene has 25% of introns, it's molecular mass – 40.000 Dalton. Define the quantity of aminoacids in polypeptide, which it codes?

5. Define length and mass of gene, if know, that it have 20% introns and it's polypeptide have mass 3.600 Dalton.

6. The consecution of nucleotides in chain of DNA is AAAGGATTCCAACCTATCGTC. Build the consecutive of aminoacids in polypeptide, if know, that 7-11 and 15-17 nucleotides are introns.

7. Weight of polypeptide is 3.000 Dalton. Weight of one region of chain DNA, in which the consecutive of aminoacids of its polypeptide code, is 93.000. What part of introns is in this region of DNA?

8. Build the fragment of replicating DNA, if know, that chain contain the following nucleotides: AAAGTACCTTTCC.

9. Chain of DNA has the following nucleotides: CGTATCAAGTTTCGCCCAT. Build the consecutive of nucleotides in mRNA.

10. Molecule of DNA has 15% adenine nucleotides. What is percent of other nucleotides in it?
