#1
Front (Question)

What does gene expression involve?

Back (Answer)

Gene expression involves the transcription and translation of DNA sequences. Only a fraction of the genes in a cell are expressed

#2
Front (Question)

Describe the structure of RNA

Back (Answer)

RNA is single stranded. It is composed of nucleotides containing a ribose sugar, phosphate and base. The bases are adenine, uracil, guanine and cytosine.

#3
Front (Question)

mRNA

Back (Answer)

mRNA is transcribed from DNA in the nucleus and translated into proteins by ribosomes in the cytoplasm A group of 3 bases on the mRNA molecule form a codon and codes fot a specific amino acid

#4
Front (Question)

tRNA

Back (Answer)

tRNA (transfer RNA) folds due to complementary base pairing A group of 3 bases in tRNA forms an anticodon. A tRNA molecule has an anticodon at one end and an attachment site for a specific amino acid at the other end Each tRNA carries its specific amino acid to he ribosome

#5
Front (Question)

rRNA

Back (Answer)

Makes up the ribosome along with proteins
