During PCR:

72 C is required for DNA denaturation

94 C is required for DNA denaturation

94 C is required for primer annealing

72 C is required for Taq polymerase

Ins 9q2.12 means:

Invertion of the whole chromosome 9

Invertion of short arm of chromosome 9

Insertion of long arm of chromosome 9

Which of the following is a characteristic of cancer cells?

Both copies of the tumor suppressor gene has to be mutated

Cells are growing slower than healthy tissue

Can be caused by de-activation of oncogene(-s)

It can travel by blood to other tissues

In the DNA fingerprinting shown here find out which male is the biologic father of the child?

Male 2

Male 1

Male 1 and male 2

None of them

It is true, that in case of balanced translocation:

The length of exchanged DNA fragments is the same

Clinical symptoms are usually m… severe than in case of unbalanced translocation

We observe deletion within one … chromosomes involved in translocation..

We can not detect such alteration … use of MLPA

Karyotype:

Enables detection of structural chromosomal alterations

Requires sterile conditions

Can be performed on the basis of paraffin embedded tissues

Can be performed only on the basis of dividing cells

Find the correct karyotype(-s) when the female patient has a down syndrome:

47 XX, +21

46 XX, t(

47 XXY

45 X0

The spread of cancerous tissue from one location to another is called:

Malignant

Metastasis

Migration

Hybridization

Mark the organelle(-s) where the process of aerobic respiration (energy) takes place:

Endoplasmic Reticulum

Nucleus

Mitochondria

Golgi complex

DNA molecules can be cut into sections by using:

Taq Polymerase

Restriction Enzymes

Restriction Enzymes Reverse transcriptase

Helicase

Which of the following may contribute to cancer development?

Nonsense mutation in the MSH2 gene

Deletion of TATA sequence near c-myc

Frameshift mutation within the n-myc gene

None of the above answers are correct

Which of the following mutations in the c-ras gene can lead to a cancer:

TATA insertion near the first exon

Deletion of this whole gene

Insertion of two nucleotides in the first exon

Substitution of four nucleotides in the first exon

Mitochondria are:

Involved in the secretion of proteins

Membrane bound structures specialized for digestion

Energy processing organelles

Storing fats

A promoter on the DNA is recognized by … 1……….to……..2……..

1: DNA polymerase, 2: stop transcription

1: RNA polymerase, 2: start transcription

1: RNA polymerase, 2: stop transcription

1: DNA polymerase, 2: start transcription

What is true?

The transfer of information from DNA to RNA is referred to as translation

A codon is a group of 4 nucleotides that codes for one amino acid

Translation occurs in eukaryotes on ribosomes located in the Golgi body

Silent mutations have no effect on the phenotype

Denaturation involves:

Heating between 90 and 98 degrees Celcius

Heating between 40 and 60 degrees Celcius

Heating between 70 and 72 degrees Celcius

Is not necessary in a Real-Time PCR
