DNA. We have heard that we are a product of our DNA. But where is it? How do we "get" our DNA? It is passed to us, from our pare

nts, but in what form? Several vocabulary words associated with inheritance are used interchangeably and sometimes, incorrectly. Let's see if you can clear this up for someone just learning about inheritance and cell structure.

Answer:

During cell division, genetic material of parents in the form of genes and alleles is transferred to the offspring. DNA is responsible for encoding genetic information.

Explanation:

DNA consists of genetic information in the form of nucleotide which are nothing but chemical compounds composed of phosphate, sugar and four nitrogenous bases. DNA consists of two chains made up of nucleotide with alternate sugar and phosphate group.  

All living beings exhibit genetic information forms their ancestors and hence they carry genetic material from two parents in case of sexual reproduction and one parent in case of asexual reproduction. Genes carry allele which is responsible for expressing any physical trait.

Describe two examples of how an understanding of genetics is making new fields of health care(treatment or diagnosis)possible?
WARRIOR [948]

Answer:

Genetics is a branch of science that deals with the study of genes, their sequence, function, variation, and heredity.

Increasing understanding of genetics help in making new fields of health care, for example,  

  • Gene therapy helps in treating various genetic diseases such as cystic fibrosis et cetera.
  • Molecular genetics help in the development of more precise methods for diagnosis such as ELISA.
  • Pedigree analysis and karyotypes help in early detection of possible hereditary diseases.
  • DNA fingerprinting helps in detecting criminal suspects, paternity test, identification of dead organism et cetera.

Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur
MakcuM [25]

Answer:

Option (e).

Explanation:

Meiosis may be defined as the process of cell division in which a single parent cell divides into four daughter cells. The chromosome number reduces to half in meiosis.

Crossing over is the process of exchange of genetic material between the homologous chromosomes of the non-sister chromatids. Crossing over will bring variation in the gametes. Hence, the absence of crossing over results in the formation of gametes with less genetic variation.

Thus, the correct answer is option (e).
