What is pre-mRNA?

Back

messenger RNA that is produced from transcription and has yet to have had its introns spliced.

Front

What are van der Waals interactions?

Back

the weakest of all intermolecular attractions between molecules that are distant-dependent.

Front

What is RNA splicing?

Back

a removal of large portions of the RNA molecule that is initially synthesized.

Front

What is a cell?

Back

Front

What is translation in biology?

Back

process that occurs in the cytoplasm where the mRNA code is read and translated into protein.

Front

What is the role of RNA polymerase?

Back

enzyme that synthesizes RNA from a DNA template during transcription.

Front

What is the function of ribosomes?

Back

cellular structures that synthesize proteins by translating mRNA.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is a codon?

Back

a sequence of three nucleotides which together form a unit of genetic code in a DNA or mRNA molecule.

Front

What is the significance of introns?

Back
