Central dogma (1)

Traits of life

6

#1

⬆degree of chemical and structural complexity

#2 (capacities)

• To self replicate

• To evolve

• To extract, transform and use E

• To sense and respond to the environment

#3

Function for each component and they interact in a regulated fashion

Requirements for life

Large organic molecules + continual input of E (or they decay)

Why are cells open systems?

Bc they require the import of E and nutrients and the export of waste

What does the selective membrane do?

Allows a greater C of nutrients and synthesized products INSIDE

True or False: proteins accomplish most molecular functions

True

Definition of central dogma

Flow of information : DNA makes RNA, RNA makes proteins

Number of combinations of RNA

4³ = 64

Types of RNA needed during translation (3)

tRNA, mRNA, rRNA
