Lecture 1 - Building blocks And Linear Biopolymer Flashcards
What do common element of biopolymer form?
Backbone
What do characteristic element form?
Side chains
What re the 3 characteristics if an informational biopolymer
Linear, unidirectional and asymmetric
What is the characteristic element and the common element of nucleotides?
Heterocyclic base and pentose sugar phosphate
What is the difference between ribose and deoxyribose (and what is the DNA benefit from that difference)?
Ribose contains a OH group at 2’ and deoxyribose does not = more resistant to cleavage by hydrolysis which gives better stability.
What does the presence of T instead of U do in DNA?
It makes some chemical damages easier to repair
What is the common element of proteins?
COOH (carboxyl) group and NH2 (amino) group
How many amino acids are there and what are the types?
There is 20 AA and they are separated in 3 categories: Hydrophobic, Hydrophilic and special
What are the energized monomers for nucleotides and AA?
Nucleoside triphosphates (NTPs) and amino-acyl tRNA esters
The Tm of DNA depends on what?
On proportion of G-C base pairs (higher proportion = higher Tm)
