By using multiple probes labeled with a mixture of different fluorescent dyes, scientists are able to label each chromosome in its own unique color.

Scientists make a person’s genes fluoresces by having to name a variety of chromosomes on what color would variant. What would it do is that it can find it’s whole color scheme in order to locate the chromosomes which is basically a spectral karyotype.

Explanation:

Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. ... Differentiation dramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals.

PLEASE HELP

Colt1911 [192]

Answer:

The correct answer will be option D (they are complementary).

Explanation:

Complementary DNA or cDNA is an edited DNA molecule synthesized from a single-stranded RNA called mRNA. The reaction of cDNA formation from mRNA is catalyzed by an enzyme called "reverse transcriptase".

The cDNA strands formed is also known as a complementary copy of mRNA as it contains no introns or non-coding sequence in its sequence similar to mRNA. cDNA is used in recombinant DNA technology to clone eukaryotic genes in prokaryotes.

Thus, option D (they are complementary) is the correct answer.

A series of enzymes catalyze the reaction X Y Z A. Product A binds to the enzyme that converts X to Y at a position remote from

nirvana33 [79]

Answer:

Option B, an allosteric inhibitor.

Explanation:

As the enzyme activity decreases, it is not possible for A to be a coenzyme (most likely would increase the enzyme activity), a substrate (increases activity of enzyme by Le Chatler's principle) or an intermediate (no effect). A is unlikely to be a competitive inhibitor as this would not decrease the activity of the enzyme, only reduce the rate of conversion of substrate to product. A is most likely an allosteric inhibitor which binds to another site on the enzyme (other than the active site), resulting in a change in conformation of the enzyme which reduces the enzymatic activity.

How can a zygote receive an abnormal chromosome number?

noname [10]

Explanation:

Some chromosomal conditions are caused by changes in the number of chromosomes. These changes are not inherited, but occur as random events during the formation of reproductive cells (eggs and sperm). An error in cell division called nondisjunction results in reproductive cells with an abnormal number of chromosomes

Chromosome abnormalities often happen due to one or more of these: Errors during dividing of sex cells (meiosis) Errors during dividing of other cells (mitosis) Exposure to substances that cause birth defects (teratogens)
