Unit 3.1 Review

 Base your answer to the following question on the structures represented in the diagram below. What is the relationship between these three structures?

• DNA is made up of proteins that are synthesized in the cell.

• Protein is composed of DNA that is stored in the cell.

• DNA controls protein production in the cell

• The cell is composed only of DNA and protein.

Which of the following best describes the relationship between genetic mutations and our physical characteristics?

• Genetic mutations always cause a phenotypic change.

• Genetic mutations do occur, but don't cause phenotypic changes,

• Genetic mutations only cause a phenotypic change if it causes a change in the protein.

How will the mutation below affect the organism?

Original DNA: CCC

Mutated DNA: CCA

• The mutation will cause a genotypic change ONLY

• The mutation will not cause a genotypic change, but will cause

  a phenotypic change.

• The mutation will cause a genotypic and phenotypic change.

Using the chart attached determine the hair color of this individual if their DNA code is

Height: GTA-ACG

Hair Color: TAG-CAA

• Tall and Black hair

• Short and Black Hair

• Tall and Light Brown Hair

• Short and Light Brown Hair

What process is taking place in the image?

• DNA Replication

• Transcription

• Translation

• Glycolysis

What best describes why its possible to take a gene from a pig and insert it into a human?

• The genetic code is universal, all life has the same DNA structure

• Humans and pigs are closely related and share many genes

• Humans and Pigs have the same cell structures

Which choice describes DNA after replication has taken place?

• one molecule with two original strands and one molecule with two new strands

• two molecules, each with one original and one new strand

•  two molecules, each with two new strands

•  two molecules, each with two old strands

Genes for medically important Human proteins can be cloned and inserted into bacteria, as shown in the diagram below.

Why can bacteria recognize a human gene and then produce a human protein?

• DNA replication in bacteria and humans is the same process.

• Bacterial cells contain the same organelles as human cells.

•  Basic components of DNA are the same in humans and bacteria.

• Bacterial and human cells contain the same kind of chromosomes.

The diagram below shows a portion of a DNA molecule. The letters in the diagram represent the four bases: adenine (A), thymine (T), guanine (G), and cytosine (C). Which sequence of bases do the question marks represent?

• C-A-C

• G-C-A

• G-A-C

• T-C-A

Using the DNA strand AGC TTG, which of the following statements best describes DNA replication?

• The strand TCG AAC is produced by complementary base pairing with DNA.

• The strand TCG AAC is produced by complementary base pairing with RNA.

• The strand UCG AAC is produced by complementary base pairing with DNA.

• The strand UCG AAC is produced by complementary base pairing with mRNA.
