Introduction to Molecular Biology

Question 1

what does molecular biology focus on

Answer 1

studies gene structure and function at the molecular level

Question 2

advantages of molecular biology

Answer 2

Enables people understand the interactions between DNA, RNA and protein biosynthesis

Question 2

what are the universal priciples of living cells

Answer 2

1. Genetic information stored in the chemical sequence of DNA is duplicated and passed on to daughter cells
2. Linear chemical sequences stored in DNA code for both the linear sequences and three-dimensional structures of RNAs and proteins
3. Macromolecular structures assemble from subunits
4. Membranes grow by expansion of pre-existing membranes
   5.Signal-receptor interactions target cellular constituents to their correct locations
5. Receptors and signalling mechanisms allow cells to adapt to environmental conditions
6. Cellular constituents move by diffusion, pumps, and motors
7. Molecular feedback mechanisms control molecular composition, growth, and differentiation
