DNA to Proteins

Every organism has cells that contain strands of DNA. A single strand is made of millions of particles called nucleotides and these nucleotides come in four different types which scientist have labelled A, C, T, and G. A gene is special stretch of DNA (a sequence of A's, C's, T's, G's) that code for proteins (made up of amino acids).

These proteins are responisible for determining traits like eye color, skin color, and freckles. If there is a mistake in the sequence of A's, C's, T's, and G's, then this may affect the structure and function of the protein or the wellbeing of the organism.

DNA makes a molecule called RNA which then makes proteins. You can use RNA sequences (codons) to determine which amino acids will be in your protein. Choose the amino acid that pertains to the following codon sequence: UUA?

• Phenylalanine

• Leucine

• Serine

• Tyrosine

Where does TRANSCRIPTION occur?

• Nucleus

• Ribosome

• Cytoplasm

• Mitochondria

​ (a)   : forms part of ribosomes, cell's protein factories

​ ​ (b)   : brings amino acids from cytoplasm to a ribosome to help make growing proteins.

​ (c)   : intermediate message that is translated to form a protein

• rRNA

• tRNA

• mRNA

If there is an error in transcription, what could happen as a result?

• The nucleotides that make up the protein will change.

• The protein that is made will not be affected.

• New amino acids will be created to make a new protein.

• The protein that is made may have a different structure or function.

What is the name of the process in which DNA is transcribed into RNA?

• Photosynthesis

• Protein Synthesis

• Translation

• Transcription

When these bond together, they form a protein
