1、 The template strand has a sequence complementary to that of the RNA transcript.（ ）

A:对
B:错
答案:
对

2、 The coding strand has the same sequence as that of the RNA transcript.（ ）

A:对
B:错
答案:
错

3、 Chromosome contains a linear array of genes and each gene resides at a particular location on the chromosome.（ ）

A:对
B:错
答案:
对

4、 Transposable elements (TEs), also known as “jumping genes,” are DNA sequences that move from one location on the genome to another location.（ ）

A:对
B:错
答案:
对

5、 DNA polymerase are essential for DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.（ ）

A:对
B:错
答案:
对

第二章 单元测试

1、 DNA sequences that are highly enriched in G–C base pairs typically have high melting temperatures. Therefore, PCR amplification is greatly hindered by the presence of G–C-rich regions within the template.（ ）

A:对
B:错
答案:
对

2、 The lacZ gene can be used to screen bacteria containing recombinant plasmids. A special plasmid carries a copy of the lacZ gene and an ampicillin-resistance gene.（ ）

A:对
B:错
答案:
对

3、 We use Lipid mediated gene delivery as example. It uses lipids to cause a cell to absorb exogenous DNA since they are both made of a phospholipid bilayer.（ ）

A:对
B:错
答案:
对

4、 When you doing transgenic plant, you could do overexpression, gene knock-down or gene knock out. Overexpression usually refers to an experiment when DNA is added to the cell to force expression of the gene to a much higher than normal level.（ ）

A:对
B:错
答案:
对

5、 The technique we use for gene knock down is small interfering RNA (siRNA). Sometimes we call short interfering RNA or silencing RNA, it is a class of single-stranded RNA non-coding RNA molecules, 20-25 base pairs in length, and operating within the RNA interference (RNAi) pathway.（ ）

A:对
B:错
答案:
错

第三章 单元测试

1、 In the process of electrophoresis, the protein with the smallest molecular weight moves the slowest.（ ）

A:对
B:错
答案:
错

2、 The antibody consists of two heavy chains, two light chains and hinge region.（ ）

A:对
B:错
答案:
对

3、 Most antigens have several epitopes.（ ）

A:对
B:错
答案:
对

4、 In the mass spectrometry, the smaller ion requires less time to traverse the chamber.（ ）

A:对
B:错
答案:
对

5、 X-ray crystallography is only suitable for the determination of crystal structure.（ ）

A:对
B:错
答案:
对
