In order to determine if individuals from separate populations are indeed distinct species, Drosophila biologists often test to
faust18 [17]

Answer:

Biological species contest.

Explanation:

Different species concept are introduced to describe the exact definition and classification of species. Some species concept are biological species contest, morphological species concept and ecological species contest.

According to biological species contest, the group of individual that can breed among themselves and not with the other group. Here, the Drosophila species has been classified by the biologist depending on their mating ability to their group of individual only.

Thus, the answer is biological species contest.

A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
Reil [10]

Answer:

From the diagram X = <u>base pairs</u>

Explanation:

Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.

Nucleotides comprise:

  • a 5-Carbon deoxyribose sugar,
  • one nitrogenous base (adenine, guanine thymine, and cytosine)
  • and a phosphate group.

Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides  Thymine and Cytosine (pyrimidine bases) along with Guanine,  and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.

What is a DNA probe?
strojnjashka [21]

Answer:

In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length which can be radioactively or fluorescently labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide substances that are complementary to the sequence in the probe.DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labelled, for example with radioisotopes, epitopes, biotin or fluorophores to enable their detection.

spanish

En biología molecular, una sonda de hibridación es un fragmento de ADN o ARN de longitud variable que puede marcarse de forma radiactiva o fluorescente. Luego puede usarse en muestras de ADN o ARN para detectar la presencia de sustancias nucleotídicas que son complementarias a la secuencia en la sonda. Las sondas de ADN son tramos de ADN monocatenario utilizados para detectar la presencia de secuencias complementarias de ácido nucleico (secuencias diana) por hibridación Las sondas de ADN generalmente están marcadas, por ejemplo, con radioisótopos, epítopos, biotina o fluoróforos para permitir su detección.
