Select the correct option/options regarding eukaryotic and prokaryotic ribosomes / Kies die korrekte opsie/opsies rondom eukariotiese en prokariotiese ribosome:

Prokaryotic ribosomes are larger than eukaryotic ribosomes / Prokariotiese ribosome is groter as eukariotiese ribosome

❌

Eukaryotic ribosomes are composed of a 60S large subunit and a 40S small subunit / Eukariotiese ribosome bestaan uit 'n 60S groot subeenheid en 'n 40S klein subeenheid

✅

Prokaryotic ribosomes can be free-floating or membrane-bound / Prokariotiese ribosome kan vryswewend of membraangebonde wees

❌

Prokaryotic ribosomes are thought to have evolved from eukaryotic ribosomes, with additional complexity arising from the need to regulate protein synthesis in larger, more complex cells / Daar word vermoed dat prokariotiese ribosome uit eukariotiese ribosome ontwikkel het, met bykomende kompleksiteit wat voortspruit uit die behoefte om proteïensintese in groter, meer komplekse selle te reguleer

❌

Eukaryotic ribosomes are always membrane-bound / Eukariotiese ribosome is altyd membraangebonde

❌

Select what is correct when discussing ribosomes. / Kies wat korrek is wanneer ribosome bespreek word.

Ribosomes are made up of RNA and proteins / Ribosome bestaan uit RNS en proteïene

✅

Ribosomes are molecular machines that carry out protein synthesis / Ribosome is molekulêre masjiene wat proteïensintese uitvoer

✅

Ribosomes are made up of a single subunit / Ribosome bestaan uit 'n enkele subeenheid

❌

Ribosomes are made in the cytoplasm / Ribosome word in die sitoplasma gemaak

❌

Ribosomes are always found free in the cytosol / Ribosome word altyd vry in die sitosol gevind

❌

Proteins made by the ribosomes share the same destiny / Proteïene wat deur die ribosome gemaak word deel dieselfde bestemming

❌

✅

A network of lamins that line and strengthen the nuclear envelope in animal cells. / 'N Netwerk van lamiene wat die kernmembraan voer onderlyn (uitvoer) en versterk in dierselle.

✅

Nucleoporins form the nuclear pore complexes within the nuclear envelope. / Nukleoporins vorm die kernporiekomplekse binne die kernmembraan.

✅

The nuclear envelope has a single membrane. / Die kernmembraan het 'n enkele membraan.

❌

All molecules can pass unassisted through the nuclear pores. / Alle molekules kan sonder hulp deur die kernporieë beweeg.
