Question

In eukaryotic ________________, DNA is complexed with proteins to form ________________. The paternal and maternal copies of human Chromosome 1 are ________________, whereas the paternal copy of Chromosome 1 and the maternal copy of Chromosome 3 are ________________. Cytogeneticists can determine large-scale chromosomal abnormalities by looking at a patient's ________________. Fluorescent molecules can be used to paint a chromosome, by a technique that employs DNA ________________, and thereby to identify each chromosome by microscopy.

1) bands, extended, homologous, nonhomologous, karyotype, hybridization
2) chromatin, kinetochore, chromosomes, condensation
3) bands, chromatin, homologous, nonhomologous, karyotype, hybridization
4) extended, kinetochore, chromosomes, condensation

Answer 1

In eukaryotic chromatin, DNA is complexed with proteins to form chromatin, homologous chromosomes are the same type, such as two copies of Chromosome 1, but nonhomologous chromosomes are different types, like Chromosome 1 and Chromosome 3. A karyotype is used to determine chromosomal abnormalities, and chromosome painting via DNA hybridization allows for their identification under a microscope.

Step-by-step explanation:

In eukaryotic cells, DNA is complexed with proteins to form chromatin. The paternal and maternal copies of human Chromosome 1 are homologous, whereas the paternal copy of Chromosome 1 and the maternal copy of Chromosome 3 are nonhomologous. Cytogeneticists can determine large-scale chromosomal abnormalities by looking at a patient's karyotype. Fluorescent molecules can be used to paint a chromosome, by a technique that employs DNA hybridization, and thereby to identify each chromosome by microscopy.

Therefore, the correct statements to fill in the blanks are: chromatin, chromatin, homologous, nonhomologous, karyotype, hybridization.Cytogeneticists can determine large-scale chromosomal abnormalities by looking at a patient's karyotype. Fluorescent molecules can be used to paint a chromosome by a technique that employs DNA hybridization, and thereby identify each chromosome by microscopy.
