1) Where in the heck did Class I transposons originate? a DNA mutations. b Bacteria. c Prophages. d Retroviruses. 2) What do you think about humans only having about 22,500 genes but we contain about 100,000 proteins?! a The production of quaternary shape in proteins can contribute to protein variation. b That's the work of the spliceosome! c Post-translation modifications in the Golgi Apparatus are responsible for some of that. d All the answers are correct.
Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
