Study Set Content:
For DNA, the pentose is
deoxyribose
whereas for RNA, the pentose is
Ribose
The nucleobases are for rna
thymine, guanine, cytosine, and uracil
The nucleobases are further divided into
purines and pyrimidines
Nucleobase alone
Nucleobase
: Nucleobase + Pentose
• Nucleoside
Nucleobase + Pentose + Phosphate(s)
Nucleotide:
: Polymerisation of nucleotides. Nucleotides are linked through 3'-5' C phosphodiester linkages
Nucleic Acid
Carbon 5 and 3 have
ester
(blank) attaches to one end of an mRNA molecule and then travels along the length of the
rRNA
As it travels along the strand, the nucleic acid bases on the mRNA are read as
triplets
The tRNA that recognizes that triplet is bound and brings the (blank) coded by that triplet
amino acid
The protein is constructed on tRNA and transferred from one tRNA to the next until the full (blank) has been completed.
protein
is the target for some important antibacterial agents such as streptomycin, tetracycline, chloramphenicol and erythromycin – prevent protein biosynthesis
Ribosomal RNA
Most are protein that are crucial to the body’s communication process Acts as the cell’s ‘letter boxes’ and receive message from chemical messenger (neurotransmitters or hormones)
Receptor
is the study of how drugs interact with receptors
Pharmacodynamics
bind to the receptor and causes it to change shape, resulting in a message being received by the cell.
Chemical Messenger
small molecules (acetylcholine, norepinephrine (noradrenalin), dopamine, and serotonin) released from nerve endings and are crucial to the mechanism by which nerves transmit messages to cells.
Neurotransmitter
Nerves do not make direct contact with their target cells and the separation between them is called the
synaptic gap.
When a nerve is active, it releases a neurotransmitter, which diffuses across the synaptic gap and binds with a receptor in the (blank)of the target cell
cell membrane
