    Liberty University BIOL 101 Q uiz 7 C omplete S olution C orrect A nswer K ey Which of the following is not a role of the ribosome or its subunits? Which of the following sequences best represents the overall flow of information in a cell? Which of the following decisions is essential to a recombinant DNA project? The two major problems that transcription solves for the cell are The structure of DNA was unraveled using Once the protein release factor enters the ribosome, other releasing factors enter as well. The ribosome responds by coming apart and releasing the new protein. This process is called A three - dimensional, folded molecule shaped like an “L” with an anticodon at one end and an amino acid attachment site at the other end: Biological information must exist because In the translation process, tRNA molecules are also called “adapter” molecules. Why? What is their function? Which of the following is part of tRNA's role in translation? DNA was discovered by Friederick Miescher; he isolated it from DNA contains two chains of nucleotides in which ______ and ______ alternate in supporting each chain structurally. Which of the following phrases best describes the role of mRNA in gene expression? The main difference between a germ cell and a somatic cell is that the somatic cell There are more than four kinds of amino acids in proteins. Each kind of amino acid must be coded for in mRNA. Thus, a short sequence of mRNA bases called a(n) _________ is used to code for each amino acid in the translation process. A useful, isolated gene can be inserted into a human cell of choice by In human history mutations have

    Peptide bonds are formed during the __________ stage of translation. When the organism expresses a set of genes, the result is the characteristics of that organism. These characteristics are called its In the process of transcription, the base sequence in the molecule _______ is read by the molecule _________ , an enzyme that makes an RNA molecule. A ribosome is best described as A retrovirus can be altered so that it can take foreign DNA into a host cell. It is altered by In order to elongate mRNA, RNA polymerase must The same “gene” can be used to code for two different proteins in two different tissues of the body of the same organism. How is this possible? PCR isolates one DNA sequence away from many others by Which of the following is not true of the ligase molecule Consider a picture of a DNA molecule. What would be different about the DNA double helix’s width if occasionally adenine paired with guanine and cytosine paired with thymine? Why is the word “translation” used for protein production? Protein production is the process of What is one value of degeneracy in the genetic code? In bacterial (prokaryotic) cells, the front end of a strand of mRNA can begin translation on a ribosome while the tail end is still being transcribed by RNA polymerase. How is this possible Which of the following is not involved at all in making a glycoprotein If part of a DNA strand’s base sequence reads – GGTACCTA -- what mRNA base sequence would be transcribed from that DNA sequence What are two structural differences between a ribonucleotide and a deoxyribonucleotide In what way is information expression in a cell superior to that in building construction?
