RNA and protein synthesis

Question 1

What is protein synthesis?

RNA and protein synthesis

Answer 1

Productio of proteins from the information contained within a cell’s DNA
Involves 2 main stages: Transcription and Translation

Question 2

What is messenger RNA (mRNA)?

Answer 2

Made during transcription
Carries genetic code from the DNA to ribosomes where it is used to make a protein during translataiob
mRNA is a single polynucleotide strand
Groups of 3 adjacent bases are called codons

Question 3

What is transfer RNA (tRNA)?

Answer 3

Involved in translation
Carries amino acids that are used to make proteins to the ribosomes
tRNA is a singly polynucleotide strand that’s folded into a clover shape
Hydrogen bonds between specific base pairs hold molecule in this shape
Every tRNA molecule has a specific sequence of 3 bases at one end called an anticodon
Also has an amino acid binding site at other end
