A- site of ribosomes

the point of entry for the amino-acyl tRNA

2

mRNA

carries the information during translation, and transcription.

3

P- site of ribosomes

where the peptidyl tRNA is formed in the ribosomes

4

promoter

a region of DNA that initiates transcription of particular gene

5

rRNA

the cell structure that is the site of protein synthesis in all living cells

6

tRNA

recognizes the codons of mRNA and it bonds to the correct amino acid

7

transcription

the process that converts DNA to RNA copy

8

Translation

the decoding of RNA or mRNA into a sequence of amino acids

9

codon

a series of three adjacent bases in one polynucleotide chain of a DNA or RNA molecule, which codes for a specific amino acid.

10

okazaki fragments

short segment of DNA synthesized away from the replication fork on a template strand during DNA replication
