Protein Synthesis- GCSE Biology

A section of DNA that codes for a particular protein is called a .............

• gene

• chromosome

• cytoplasm

• nucleus

Proteins consist of long chains of ..................

• amino acids

• fatty acids

• glycerol

• carbohydrates

How many bases are needed to code for one amino acid?

• 1

• 2

• 3

• 4

All DNA regions code for amino acids

• true

• false

Non-coding DNA regions can switch genes on and off controlling whether or not a gene is used to make a protein

• true

• false

A random change in the DNA sequence

• mutation

• reduction

• oxidation

• deletion

A genetic variant is a different version of a..........

• gene

• nucleus

• chromosome

• DNA

Use the table to determine the amino acids that are coded for by a base sequence above the table

• Serine-threonine-asparagine-glutamic acid

• Proline-threonine-phenylalanine-glutamic acid

• Serine-threonine-tryptophan-glutamic acid

• Serine-tryptophan-asparagine-glutamic acid

This stage of protein synthesis takes place in the cell's nucleus

• transcription

• translation

This stage of protein synthesis takes place in the cell's cytoplasm and involves subcellular structures called ribosomes

• transcription

• translation
