Cap
(Science: abbreviation) catabolite (gene) activator protein.
1. Any anatomical structure that resembles a cap or cover.
A methylated guanine residue added in reverse polarity (ie 3'pMeG5'ppp5'NpNp3') to the 5' end of eukaryotic mRNA during transcription initiation. The cap binds a cap binding protein and acts as an initial binding site for ribosomes during translation.

Capsduction
A DNA transfer system in Rhodobacter capsulatus where the donor DNA is carried in a phage-like structure known as a gene transfer agent (GTA).
cap (also pileus)
The fleshy or leathery structure upon which the spore-bearing structures occurs in a fungal fruit body.
Cap: A methylated guanine residue (GTP), which is added to the 5' end of eukaryotic mRNAs in a post-transcriptional reaction. It protects the mRNA against 5'-exonuclease, stabilises the mRNA and enhances its translation.
5' cap A structure at the 5' end of eukaryotic mrna that stabilizes the mrna and enhances its translation.
A 5' cap, a guanine triphosphate nucleotide, thus named because it binds to the 5' end of the mRNA;
The methylated cap prevents the 5' end from being degraded by exonucleases ...

(Knee Cap)
The patella (Figs. 255, 256) is a flat, triangular bone, situated on the front of the knee-joint.
[edit] Cap phase
The Golgi apparatus surrounds the now condensed nucleus, becoming the acrosomal cap.
Note how the tails of the sperm point inward. This orientation occurs during the acrosomal phase.

CaP CURE (Cure of Cancer of the Prostate) was founded in 1992 by Michael Milken after the former financier was diagnosed with the disease.
Cap site: Two usages: In eukaryotes, the cap site is the position in the gene at which transcription starts, and really should be called the "transcription initiation site".
CAP - A 7-methyl guanosine residue linked 5' to 5' through a triphosphate bridge to the 5' end of eukaryotic mRNAs; facilitates initiation of translation.
CHAIN TERMINATOR - See DIDEOXYNUCLEOTIDE.
CAP consists of two identical polypeptides (hence it is a homodimer). Toward the C-terminal, each has two regions of alpha helix with a sharp bend between them.

A cap is added to the 5' end and a poly-A tail (150 to 200 Adenines) is added to the 3'end of the molecule.
root cap A thimble-shaped group of cells found at the tip of roots; it functions to protect the meristem.
root hair A root epidermal cell that functions in water absorption.
A cap of 7-methylguanine (a series of an unusual base) is added to the 5' end of the mRNA; this cap is essential for binding the mRNA to the ribosome.
These cells possess a pre-formed reggie cap scaffold consisting of densely packed reggie microdomains. PrPc is targeted to the lymphocyte reggie cap when activated by antibody cross-linking, and induces a distinct Ca2+ signal.
What can humans do to keep a cap on Lyme disease?
Essentially, if you're in a Lyme disease endemic area--an area where Lyme disease is a big risk and a chronic risk--it's there, and there's very little you can do to actually eradicate it.
When it's time to reproduce, they develop a stalk and cap. The mushroom that you see popping out of the ground. It's only one part of the fungus. On the bottom of that cap are a set of gills that have little clubs with fungus spores.
Acetabularia - genus of unicellular marine algae. These organisms comprise an enormous single cell consisting of a cap, stalk and rhizoid and can be up to 10 cm in size.
Accordingly, many plants, which are unable to physically avoid predators that might want to eat them or harm them in some other way, produce toxins that affect cellular actin and microfilaments as a defensive mechanism. The death cap mushroom, ...
