Translation

​Translation

​What are the building blocks of proteins?

Time to make the protein!!

Translation – process by which mRNA is used to synthesize proteins

​

using the copied recipe mRNA to add ingredients together ​to make protein

​

​Translation

​

Multiple Choice

What is translation?

• the process in which DNA is copied to make another molecule of DNA

• the process in which DNA is coded into mRNA

• the process in which mRNA is decoded into a protein

• the process in which enzymes break down mRNA

​Protein synthesis – cellular process used to make proteins, translation

​

​

​After transcription, mRNA leaves the nucleus through a nuclear pore

​

​Ribosomes is the chef adding the ingredients together

​

​

​Ribosome

​

Multiple Choice

Where is RNA made into protein?

• Cytoplasm

• Nucleus

• Ribosome

• Cell Membrane

rRNA (ribosomal RNA) – non-coding strands of RNA that serves as the subunits of ribosomes

​

Ribosome – serves as the site of protein synthesis (translation) where amino

acids are linked together to build proteins

​

​rRNA

​

​The ​Ribosome reads the mRNA three ingredients at a time

​

Codon: a sequence of three nitrogen bases in DNA or mRNA that codes for an amino acid

​

​

​Ribosomes

​

The mRNA is read in a set of three nitrogen basses​

the codon determines the amino acid ​

​

Amino acids – a group of 20 chemicals that are the building blocks of proteins

​

​Codon

​

Multiple Choice

How many nucleotides make up a codon?

• 1

• 3

• 5

• 15

tRNA: non-coding strands of RNA that carry amino acids to protein-building ribosomes

​

​

the assistant chef;

it delivers amino acids that match the codon ​"ingredients"

​tRNA

​

this process repeats

amino acid snap together, forming a peptide bond creating a polypeptide chain

​

Fold to make THE PROTEIN!!​

​

Multiple Choice

Which of the following describes the primary structure of a protein?

• Polypeptide chain

• Pleated sheets or Helices

• 3D folding

• Two or more chains bonded together
