1

Which strand is copied?

template strand

2

What are called the mRNA base triplets?

codons

3

A cell translates an mRNA message into protein with the help of..

transfer RNA (tRNA)

4

Each tRNA have...

- specific amino acid on one end and the anticodon on the other end

5

What are the two steps of translation?

1. correct match between tRNA and amino acid
2. correct match between tRNA anticodon and mRNA codon

6

What are the 3 stages of translation?

initiation (a) elongation (p) and termination (E)

7

synthesizes protein that function in the cytosol

free ribosomes

8

synthesize proteins of endomembrane system and proteins that are secreted from cell

bound ribosomes

9

Changes in genetic material of a cell

mutations

10

changes in just one base pair of a gene

point mutations
