25 Questions6 MinutesCreated by ExploringCells101

What are the indications to perform karyotyping?

Infertility

Familiar clustering of colorectal cancers

Recurrent natural abortions

Occurence of malformations in the offspring of the patient

Diagnosing of viral infections

Mark the correct sequence of phases during mitotis

Meta – pro – ana – telo

Pro – ana – telo – meta

Pro – meta – ana – telo

Pro – meta – telo – ana

What is true about mosaicism? (!!!)

Occurs in somatic cells only

It occurs quite often in healthy cells

Every cell has the same genotype

Different genotypes in one individual

Is it true that (!!!)

Mitosis leads to creation of diploid cells

Meiosis leads to creation of diploid cells

Mitosis take place in germ cells

Mitosis takes place in somatic cells

A male patient has an invertion in one of his chromosomes, mark the correct

46 XY, ins(7p2)

46 XY, inv(2q1)

46 XX, ins(4q21)

46 XX, inv(9p13)

What process does belong to the telophase?

Cytokinesis of the cell

Formation of a new nuclear envelope

Unwinding of the chromosomes

Disappearance of the spindle

Mark true sentences

Edward syndrome is 45 X0

Down syndrome is referred as trisomy 21

Turner syndrome is referred as trisomy 18

Klinefelter syndrome is referred as 47, XXY

What can you tell about this karyotype: 46 XY, del(15)(q24;qter)

This can be detected with karyotyping

This patient has an inversion on chromosome 13

This patient is a male

This patient has an insertion on the short arm of chromosome 15

Metacentric chromosome is characterized by

The same length of arms p=q

P arm is longer than q arm (p>q)

Q arm is longer than p arm (q>p)

Is not present in human cells

Unbalanced reciprocal translocation between non-homologous chromosomes

Usually does not lead to disease

Has usually more severe clinical impact on a carrier than a balanced reciprocal translocation

Can be detected by karyotyping performed during S phase

Can be detected by karyotyping performed during interphase

What kind of mutation does lead to Down syndrome?

Robertsonian translocation between chromosomes 14 and 21

Trisomy of 22 chromosome

Polyploidy

Aneuploidy

Chromatin is made up of (!!!)

DNA only

DNA and proteins only

DNA, proteins and small amounts RNA

RNA and small amount of DNA

Tetrads are formed during: (!!!!)

Prophase 1 of meiose

Anaphase of mitosis

Anaphase 1 of meiose

Anaphase 2 of meiose

What process belongs to telophase?

Cytokinesis of the cell

Formation of new nuclear envelope

Unwinding of the chromosomes

Disappearance of the spindle

Mark the chromosomes that are present in human cells:

Telocentric

Metacentric

Submetacentric

Acrocentric

Crossing over is:

The movement of genetic material from one chromosome to another chromosome

Appears during metaphase of mitosis

The exchange of homologous portions of chromosomes

Making an RNA copy of a DNA strand
