In: Biology
Viruses are living organisms, because they contain DNA and RNA. A) TRUE B) FALSE
The field of genetics includes the study of cellular processes including transcription and translation. A) TRUE B) FALSE
Sequencing of organisms’ DNA has in many cases resulted in their original taxonomic reclassification based upon anatomical structure. A) TRUE B) FALSE
The # of chromosomes per cell never changes at any point during mitotic cell division. A) True B) False
In a diploid organism, __________line up at the metaphase plate during mitosis, ____________ line up at the metaphase plate during Meiosis I, and _________ line up at the metaphase plate during Meiosis II.
ANSWERS:
1. b) False
Because the viruses contain either DNA or RNA as the genetic material which makes them living organisms. Viruses do not contain DNA and RNA.
2. a)True
Because the genetics which is primarily the study of genes includes the study of cellular processes as well of which the translation and transcription are a part. The study of cellular processes comes under cytology or the cell biology. Genetics and cytology are interrelated.
3.a)False
Because after the DNA sequencing the organisms are reclassified based upon the genomic constitution and not the anatomical structure.
4. A) True
The number of chromosomes per cell never changes at any point during mitotic cell division. Because mitosis is the equational division. However, the amount of genetic material in each cell is doubled before the cell division. It is only during the meiosis which is the reductional division that the number of chromosomes per cell in gametes is reduced to half.
