Proteins Synthesis and Mutations

Genes contain the instructions to build all the ___________ in the body

• lipids

• carbs

• proteins

• bones

Genes are made up of:

• amino acids

• DNA bases (A, T, C and G)

• mRNA bases (A, U, C, G)

Proteins are important because they:

• proteins build the body (bones, muscle, cartilage)

• proteins direct body to do something (muscle flexing, hair growing)

• proteins support bodily functions in indirect role (assist with blood flow, help immune system responsd)

• proteins directly influence traits

• all of the above

Which statement is true regarding proteins?

• Each protein has its own own unique 3-D shape

• multiple proteins can have the same 3-D shape

• the 3-D shape of the protein does not matter

To build a protein the first step is DNA is transcribed into __________

• DNA

• mRNA

• amino acids

• proteins

If the DNA has an "A" base, the mRNA has a ________ base

• A

• T

• U

• G

• C

If the DNA has a T base, then the mRNA has a ________ base

• A

• T

• U

• G

• C

The second step to building a protein is translation. the mRNA is translated into _______

• DNA

• mRNA

• amino acids

A chain of amino acids is called ____________

• DNA

• mRNA

• protein

• lipid

• carbohydrate

Human DNA contains about 25,000 genes which means the body must build 25,000 __________ to stay alive

• proteins

• lipids

• carbs
