DNA and Protein Synthesis Review

Transcribe the following sequence of DNA into RNA:
AAG   CTT   TGC

• TTC  GAA  ACG

• UUC  GAA ACG

• TTC  GUU  UCG

• UUC  GUU  UCG

What type of bond holds together the two strands of the DNA double helix?

• Hydrogen Bond

• Peptide Bond

• Ionic Bond

• Disulfide Bond

Which of the following terms means that in each molecule of DNA made during replication there is one original strand and one new strand?

• Antiparallel

• Semi-conservative

• Complementary base-pairing

Proteins are chains of amino acids bonded together. Which is the correct sequence for making proteins?

• Information is DNA is transferred into RNA and then made into protein

• Information in DNA is formed into protein directly.

• Information in RNA mutates into DNA and then is made into protein

• Information in RNA uses thermal energy to make protein

DNA is used as a guide to rewrite the genetic code into RNA. RNA can then leave the nucleus.

• This is Transcription.

• This is Translation.

Match the following processes with their products

• mRNA

• translation

• protein

• transcription

• DNA

• replication

​ (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

What is Thymine replaced with in RNA?

• Uracil

• Guanine

• Adenine

• Cytosine

RNA goes to the ribosome where it is used as a guide to attach amino acids together. Amino acids in a chain is a protein

• This is Transcription.

• This is Translation.

What process is shown in the picture?

• commensalism

• deletion

• passive transport

• DNA replication
