will RNA and(or) DNA have an H at the 2 prime position
Does RNA and(or) DNA have 1prime as a base, 3 as Hydroxyl for polymerization, 5 as a phosphate
What has a high stabilizing capacity (can absorb energy in reactions),is the most abundant molecule in cells (>70% of total cell mass), and is an excellent solvent.
what allows water to move easily throughout the cell
What type of bonding creates spheres of hydration
In what bonding do charges attract opposites (+ end (H) attracts O, - end (O) attracts H)
What type of interactions occur due to H-bonding, drives molecules together
making RNA from DNA. Occurs in nucleus in eukaryotes (except some in Mitochondria)
This occurs in the cytoplasm (and ER), through ribosomes. Involves making proteins (polypeptides) from mRNA template
Is translation or transcription UNIDIRECTIONAL (5'→3')
all amino acids
What macromolecules have an amino group (NH2), carboxy group (CO2H), a H atom, and an R group.
How many different kinds of monomers (3-codon) of amino acids are there in the cell
simplest amino acid
amino acid important for disulfide bonds
amino acid that bends back on itself
What are linear polymers of amino acids linked together by peptide bonds.
N terminus to C terminus
In what direction is a protein is translated or read?
when are many proteins modified?(glycosylation, etc.)
sequence and interactions
What do the structures of Amino Acid depends on?
what amino acids are found in proteins in the body
What are all the fat soluble vitamins?
What protein structure has an Amino Acid sequence and Peptide bonds?
What protein structure uses H-bonds and organizes into local folding (alpha-helices and Beta-sheets or random coils)
What protein structure has disulfide, ionic, Van Der Waals and H-bonds, hydrophobic interactions, and folds into one 3-dimensional domain?
What protein structure has disulfide, ionic, Van Der Waals and H-bonds, hydrophobic interactions and folds into multiple domains?
What carries info to ribosomes for production of proteins?
Creates ribosomal components used for protein translation
Carries AA to ribosome for attachment to nascent protein
Small nuclear RNA (snRNA)
What are the components of spliceosomes involved with mRNA splicing?
Micro RNA (miRNA)
What are regulatory RNAs involved with gene expression control?

what sugar is composed of glucose and fructose
Adenine and Guanine
What are the Purine names
Cytosine Thymine Uracil
The Pyramidine names are (CUT the Py)
β 1->4 bonds, unbranched sugar found in plants
α(1−>4) bonds, α(1−>6) branches every 8-10 glucose units. Side chains of sugar are 8-12 glucoses long(found in mucle, liver cells predominantly)
α(1−>4) bonds, unbranched
α (1->4) bonds, α (1->6) branches @ 12-25 glucose units. Side chains of sugar 20-25 glucoses long.
What are the Major Lipids of the Human Body and Are Building Blocks of Several Classes of Lipids
