An organism is _______ for a gene if it has two copies of the same allele for the gene.
vesna_86 [32]

Answer:

An organism is <u><em>homozygous</em></u> for a gene if it has two copies of the same allele for the gene.

The genotype of an organism and the interaction of the genotype with the environment determine the organism’s <u><em>phenotype</em></u> , or observable characteristics.

The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are<u><em> not linked.</em></u>

Mendel’s law of<u><em> segregation</em></u> governs which allele is expressed in an individual.

Explanation:

A homozygous trait can be described as a trait in which both the alleles of the gene are the same. Heterozygous means that the alleles of the gene will be different.

Genotype is the genetic makeup of an organism where as phenotype of the physical appearance of traits.

Mendel formulated two laws: Law of dominance and Law of Independent Assortment.

What is the importance of exosome analysis and characterization? Any help would be appreciated. Thanks in advance!
jok3333 [9.3K]

Answer:

Characterization of exosomes has become a topic of interest in medical research and molecular biology because it can provide very valuable information for early detection, disease monitoring and development of effective treatments against cancer and autoimmune diseases. Exosomes are known as one type of secreted membrane vesicles that are responsible for intercellular communication by providing means for intercellular exchange of proteins, lipids, mRNA, miRNA and DNA, contributing to intercellular communication in relevant biological processes, playing an important role in the development of several diseases, and specifically, modulating cancer microenvironment and the immune response. Exosomes and its contents also have emerged as non‐invasive biomarkers for various diseases. Exosomes composition and quantity may be directly related to the pathological state of the patient, so the characterization of exosome could be of great relevance for diagnosis.
