The human genome project identified the sequence of base pairs in human DNA and identified several genes. Which question would l

east likely lead to a scientific investigation based on these findings? Are certain humans more likely to develop genetic diseases? How can DNA be used to identify criminals? Can drugs be developed to target certain genes? Should there be laws to protect DNA information?

Answer;
D. should there be laws to protect DNA information;

The question that would at least lead to a scientific investigation based on these findings is; should there be laws to protect DNA information. 

Explanation;
Human genome project is a scientific research project with the goal of determining the sequence of nucleotide base pairs that make up human DNA, and of identifying and mapping all of the genes. Its main aim was to provide a complete and accurate sequence of the 3 billion DNA base pairs that make up the human genome and find all the estimated genes

erastovalidia [21]

Answer: Cytosol; Mitochondria

Explanation:

Anaerobic reactions occurs in the ABSENCE OF OXYGEN ONLY, and involves the breakdown of sugar molecules into lactate and occurs in the CYTOSOL of activel skeletal muscles during movement

In contrast, aerobic reactions of respiration are reactions that occurs in the presence of oxygen ONLY, and involves the breakdown of sugar molecules into carbon dioxide, water and energy (in form of ATP). It occurs within the inner membrane of the mitochondria.

Consider a study of two genes, "A" and "B". Each gene has two alleles, represented by upper- and lower-case letters. Assume that
Nata [24]

Answer:

AaBb × aabb

Explanation:

A test cross is a cross between an unknown genotype (dominant phenotype) with a homozygous recessive genotype in order to discover the actual genotype of the species exhibiting dominant phenotype.

This is because one allele of a gene is capable of masking the expression of another, the allele masking is called DOMINANT allele while the allele being masked is called RECESSIVE allele. The combination of these two alleles is termed heterozygosity.

An organism that is phenotypically dominant for a specific trait may either be heterozygous or homozygous for that gene. For example, a plant gene for tallness with an dominant allele T, and recessive allele t. This plant will need tall if the genotype is TT (homozygous dominant) or Tt (heterozygous dominant). In order to know which of these genotypes the plant actually has, a test cross is conducted.

In this example, two genes A and B are involved. For the first gene, A represents dominant allele while a represents recessive allele. For the second gene, B represents dominant allele while b represents recessive allele.

In a cross involving parents AABB (homozygous dominant for both genes) and aabb (homozygous recessive for both genes), the F1 progeny will all exhibit phenotypic dominance (AaBb).

However, we cannot know the genotype by merely looking at the phenotype. We cannot ascertain yet whether the dominance is heterozygous or homozygous, hence the need for a test cross.

The test cross is between the dominant F1 progeny and a homozygous recessive i.e. AaBb × aabb. Some of the F2 generation will show recessive traits if the unknown genotype is heterozygous.
