Answer:
The two basic function of meiosis is listed below.
1. Genetic recombination:
In meiosis crossing over occurs that results into genetic recombination.
2. Ensure constant chromosome number:
The number of chromosomes reduce to half in germ cells that reunite in sexual reproduction and ensure the survival of species by keeping constant chromosome numbers. Have a good day.
Answer:
The correct answer is <em>A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.</em>
Explanation:
PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.
Answer:
For hh, the gametes can only carry h (the recessive allele). For both heterozygous individuals (Hh), the gametes can carry the H (dominant allele) or the h (recessive allele). For Hh, the gametes can carry the H (dominant allele) or the h (recessive allele). For HH, the gametes can only carry H (the dominant allele).

The temperature in an autoclave must reach 121° C in order for sterilization to occur.
<h3>Sterilization using autoclaves</h3>
Autoclaves are used to wet-sterilize materials in the laboratory.
In order for the sterilization to be effective, the temperature of the autoclave must reach 121° C.
Also, substances to be sterilized must spend, at least, 30 minutes in the autoclave.
