Protein Synthesis

Insertion, deletion, and substitution are all examples of a change in a genetic sequence which is also referred to as (a)

• Gene

• Amino Acid

• Ribose

• Mutation

During transcription, this type of ribonucleic acid is responsible for copying the DNA and brining it out of the nucleus.

• tRNA

• mRNA

• rRNA

• dRNA

When these bond together, they form a protein

• Amino Acids

• Peptide Bonds

• Ribose

• Nucleotides

These building blocks consist of a sugar, phosphate, and nitrogen base.

• Ribose

• Nucleotide

• Gene

• Protein

During translation, this type of ribonucleic acid is responsible for delivering amino acids to help make a protein.

• mRNA

• rRNA

• tRNA

• dRNA

Which of the following is the complementary mRNA sequence to this DNA strand: AACTGAA

• UUGACUU

• TTGACTT

• AACTGAA

• AACUGAA

which process is shown?

• diffusion
• repiration
• recombination
• translation

When an extra base is inserted into the DNA sequence of a gene, the protein doesn't work. Which explains why?

• the base increases rate of translation
• the base causes DNA to be transcribed in opposite direction
• the inserted base causes the codons in the sequence to be incorrect for the desired protein
• the base signals enzymes to translate DNA rather than RNA

The genetic material of an organism is composed of

• lipids
• proteins
• deoxyribonucleic acids
• complex carbohydrates

A scientist puts nucleotide chains of UUUUUU in a test tube under conditions allowing protein synthesis. Soon they are only amino acids chains of phenylalinine. What does the experiment indicate?

• phenylalanine is composed of uracil
• UUU codes for phenylalanine
• protein synthesis malfunctions in test tubes
• proteins contain one kind of amino acids
