How is information for a specific protein carried on DNA?

• As a sequence of nucleotides

• In the double helix shape

• in the ratio of A to T

• As a pattern of phosphates and sugars

What molecule is produced at the end of transcription?

• New DNA

• Polypeptide

• mRNA

• tRNA

Where in the cell does transcription take place?

• Ribosome

• Nucleus

• Mitochondira

• Chloroplast

What is the purpose of the image?

• Preserving genetic information for future generations

• Deleting the information in the sequence produced from the DNA template

• Transcribing information in the DNA sequence for use by the cell

• Producing more nucleotides for the DNA sequence

Where does protein synthesis occur?

• At a ribosome (on the Rough ER)

• Nucleus

• Golgi Body

• Mitochondria

Which statement best describes the interaction between DNA and RNA during protein synthesis?

• mRNA carries the code to the nucleus where DNA translates the code into a protein

• DNA travels to the ribosome where RNA translates the code into a protein

• mRNA carries the code from the DNA in the nucleus to the ribosome for protein synthesis

• DNA travels to the cytoplasm while RNA remains in the nucleus

Translation can be described as-

• Replicating a DNA sequence

• The transfer of genetic instructions in DNA to mRNA.

• The process in which the genetic code in mRNA is read to make a protein.

• The process of making a protein in the nucleus.

All of the following are directly involved in translation except-

• mRNA

• amino acids

• DNA

• Ribosomes

What is the purpose of translation?

• To replicate the DNA of an organism before cell division

• To assemble nucleotides in an mRNA chain along a DNA template

• To synthesize amino acids used to unzip strands of DNA and copy the genetic code

• To translate the genetic code into a specific sequence of amino acids

A strand of mRNA containing the repeating sequence AUG AGC GAG UAG would code for which of the following amino acid sequences?

• ser-ser-ser-ser

• met-lys-lys-stop

• met-ser-glu-stop

• met-arg-lys-stop
