Cell Cycle- And DNA replication

Multiple Choice

This diagram shows the cell cycle.

Which of the following activities occur in the S phase?

Replication of the DNA

Growth of the cell

Formation of the mitotic spindle

Breakdown of the nuclear membrane

Multiple Choice

Why does DNA replicate?

To create a duplicate copy in case the original gets damaged

New cells will have a copy of the DNA

To create a new copy to replace the damaged original

Multiple Choice

During the ___ phase, DNA is replicated.

Multiple Choice

G1, S, and G2 phases are combined into one long phase called _____________.

interphase

mitosis

cytokinesis

cell cycle

Multiple Choice

Where in a Eukaryotic cell does DNA Replication take place?

Cytoplasm

Ribosomes

Nucleus

Cell Membrane

Multiple Choice

What is the end result of DNA replication?

Two identical DNA molecules each composed of one new and one original strand

Two non-identical DNA molecules each composed of one new and one original strand

Two identical DNA molecules. One is made up of the two old strands and one is made up of the two new strands.

Two non-identical DNA molecules. One is made up of the two old strands and one is made up of the two new strands.

Multiple Choice

What is happening to the DNA molecule in the figure? (Explain the first step in DNA replication)

The DNA molecule is being transcribed into RNA.

The DNA molecule is being translated into proteins.

The DNA molecule is being unzipped and separated into two strands.

The DNA molecule is being repaired.

Match

Match the following DNA base pairs.

Adenine pairs with

Thymine pairs with

Cytosine pairs with

Guanine pairs with

Thymine

Adenine

Guanine

Cytosine

Labelling

Complete the DNA molecule based on the rules for complementary base pairing

Drag labels to their correct position on the image

Multiple Choice

Which shows the correct complementary DNA strand of ATG?

ATG

TAC

TAG

CGC

Multiple Choice

What role does DNA Polymerase play in the process of DNA replication as shown in the image?

It adds free nucleotides to both strands

It unwinds the DNA helix

It initiates transcription

Multiple Choice

What happens to the DNA molecule during the second step of DNA replication?

The DNA strands are separated by helicase.

New nucleotides are added to the existing DNA strands.

The DNA strands are joined by ligase.

The DNA is packaged into chromosomes.

Multiple Choice

What is the function of proofreading during DNA replication?

To synthesize new DNA strands

To unwind the DNA double helix

To correct errors in the newly synthesized DNA

Multiple Choice

What happens during the third step of DNA replication?

The DNA strands are separated by helicase.

Primase synthesizes RNA primers.

Two identical DNA strands result.

Ligase joins Okazaki fragments.

Multiple Choice

What does the term semi-conservative mean?

DNA consists of half an old strand and half a new strand and the code stays conserved.

DNA consists of two old strands and the code stays conserved.

DNA consists of two new strands and the code stays conserved.

DNA consists of half an old strand and half a new strand and the code changes each time.

Multiple Choice

The picture below shows the steps of DNA replication beginning with step one and ending with step three.

Because you are reusing the old, or parent, DNA strand DNA replication is said to be

Semi- Conservative

Semi-discontinuous

Continuous

Fully-Conserveative
