Scientists recently studied the reproductive behavior of a yeast species. They noticed a new species emerged from two populations. This new species formed after the yeast were exposed to signaling molecules called pheromones. Both male and females release pheromones, which bind to cell surface receptors. Pheromones from the male bind to female cells. The opposite is true for pheromones secreted from female cells. This signaling action causes the yeast to change their sex type.

Explain how this phenotypic plasticity is beneficial.

Answers

Answer:

Phenotypic plasticity in yeast cells is beneficial because this allows the yeast to change its phenotype of being a male or female. This plasticity depends on the type of pheromone exposure. The ability to change phenotype increases the reproductive success of yeast cells. This condition is useful for yeast, especially if they must adapt to changes affecting their reproduction and survival. By having phenotypic plasticity, the yeast can continue to grow its population size.

Answer:

When the yeast is exposed to a pheromone, its phenotypic plasticity allows it to change its sex type, meaning if there is a yeast molecule that is releasing pheromones close to another molecule of yeast, the latter molecule will change its sex type to the opposite sex, if necessary, to reproduce. The yeast's phenotypic plasticity regarding sex type allows it to grow the population more effectively, helping the species survive.

Write a short paragraph that explains the relationship between the terms "chromosome," "gene," "DNA," and "allele."

Answers

Answer:   Genes appear throughout the length of each chromosome, and each chromosome pair has a unique set of genes. ... In a diploid organism, the two corresponding genes in a chromosome pair, or alleles, might be identical or might have different base sequences. Each parent contributes one allele in each pair.Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA !

Scientists have discovered that there are reproductive isolating mechanisms that can stop a population from interbreeding and possibly lead to the formation of a new species. What is this process called

Answers

Answer:

Polyploidy

Explanation:

The isolating mechanism that is capable of stopping a population from interbreeding, possibly leading to speciation is polyploidy.

Polyploidy is a condition in which a species of an organism will have multiple, instead of a diploid, chromosomal set as a result of an error during meiosis.

Non-disjunction during meiosis can make a gamete have a diploid number of chromosomes in the place of a haploid chromosome. A 2n gamete fusing with an n gamete will result in a triploid organism, 2n plus 2n gametes will result in a tetraploid organism, etc.

If the extra chromosomal set is from the same species, such polyploidy is termed autopolyploidy, otherwise, it is termed allopolyploidy. Having extra sets of chromosomes has the capacity to make an organism to be reproductively incompatible with normal diploid organisms of the same species. However, polyploid organisms can either self-pollinate or cross with another polyploid organism, a process that can lead to sympatric speciation.

23. A PCR reaction is performed, and the negative control demonstrates the presence of a detectable number of PCR product (amplicons) by capillary electrophoresis. What is the most likely cause?

Answers

Answer:

Contamination of the control sample (negative control) with DNA

Explanation:

The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories to amplify a target DNA fragment using primer pairs and DNA polymerase. In PCR experiments, it is imperative to include both positive and negative controls. The positive control refers to the amplification of a PCR product (amplicon) of known molecular size during PCR reaction in order to ensure the correct molecular weight of the target DNA fragment. The negative control refers to the inclusion of a sample without DNA in order to ensure that no contamination with DNA has occurred in the other samples.
