exista multe tipuri de matase de paianjen.
there are many kinds of spider silk.

toti paianjenii produc matase de-a lungul vietii lor.
all spiders make silk at some point in their life.

primul motiv este acela că niciodată nu mor flori de matase.
the first reason is that silk flowers never die.

in fiecare paianjen, exista sute de glande de matase, uneori mii.
inside each spider, there are hundreds of silk glands, sometimes thousands.

dar cel mai studiat fir de matase dintre toate este ampula majora de matase
and the most studied silk line of them all: major ampullate silk.

cum poate un singur paianjen sa produca atat de multe tipuri de matase?
how does an individual spider make so many kinds of silk?

imi place cand in laborator fiind, o noua secventa de matase de paianjen soseste.
i love when i'm in the laboratory, a new spider silk sequence comes in.

de exemplu, acest paianjen de gradina poate sa produca sapte tipuri de matase diferite.
for example, this garden spider can make seven different kinds of silks.

cand va uitati la aceasta panza de paianjen circulara, de fapt vedeti mai multe tipuri de fibre de matase.
when you look at this orb web, you're actually seeing many types of silk fibers.

ceea noi biologii matasii facem este ca incercam sa asociem aceste secvente de aminoacizi cu proprietatile mecanice ale fibrelor de matase.
what silk biologists do is we try to relate these sequences, these amino acid sequences, to the mechanical properties of the silk fibers.

cei mai multi dintre paianjeni utilizeaza o mare cantitate de matase, iar matasea este esentiala pentru supravietuirea acestora si pentru reproducere.
most spiders use copious amounts of silk, and silk is essential to their survival and reproduction.

matasea glandulei pyriformes sintetizeaza fire pentru fixarea panzei- aceasta e matasea care e utilizata pentru aderarea firelor de matase la o reactie chimica.
pyriform silk glands make the attachment cement -- that's the silk that's used to adhere silk lines to a substrate.

ce-ar fi sa vorbim despre variatia dintre speciile de paianjen, adica analizand un anumit timp de matase, de la diferite specii de paianjeni?
but how about variation among spider species, so looking at one type of silk and looking at different species of spiders?

acum voi puncta asupra valorilor rezistentei fibrei de nailon, matasea bombyx - sau viermii domestici de matase - fibra sintetica kevlar, si fibrele de carbon.
now i'm going to mark on the toughness values for nylon fiber, bombyx -- or domesticated silkworm silk -- wool, kevlar, and carbon fibers.

de exemplu, aceasta ar putea fi considerata o propozitie si atunci vom avea acest tip de zona verde iar polianinele rosii, care se repeta iar si iar si iar din nou. apoi putem avea acest lucru de sute si sute si sute de ori in interiorul unei singure molecule de matase.
so for example this would be one sentence, and you would get this sort of green region and the red polyalanine, that repeats over and over and over again, and you can have that hundreds and hundreds and hundreds of times within an individual silk molecule.
