Please answer the following questions
Cells in our body that contain only one of each type of chromosome are? Select one: a. Haploid b. Diploid c. Triploid d. somatic cells e. A &: D Cells spend the majority of their cell in this stage. Select one: a. metaphase b. anaphase c. prophase d. telophase e. interphase During mitosis, when does the nuclear membrance begin to reform or reassemble? Select one: a. metaphase b. anaphase c. prophase d. telophase e. interphase Genetic engineering involves which of the following. Select one: a. Donor or source DNA. b. Host DNA where new gene is added and eventually replicated. c. Moving genes between organisms, sometimes of different species. d. All the above. If you apply for health insurance and the company requests you give them a skin sample, should you be suspicious and why? Select one: a. No, the company just wants make sure you have clean skin. b. No, the company won't be able to really tell anything conclusion from just a small sample of skin. c. No, the skin cell is dead and no longer contains any useful DNA. d. Yes, the company must be trying to analyze your DNA but unfortunately for them they will need a much bigger sample than a few skin cells. e. Yes, the company must be trying to analyze your DNA and can discern it from the small they requested.Explanation / Answer
1)a. Haploid ( haploid is single set of chromosomes, triploid is double and triploid is triple set of chromosome; somatic cells will have as many of each type as is the ploidy of the organism)
2)e. Interphase ( it is the phase wherein it grows and prepares itself for division/ mitosis and consists of 3 phases G1, S andG2. a to d options are phases or parts of mistosis and are comparatively short.
3) d. Telophase ( this is the phase after anaphase where the chromosomes have been pulled to their respective poles and the cells begin to prepare for cytokinesis)
4)d. All of the above ( genetic engineering is the deliberate modification of genetic material and all the above options would be required depending on the type of experiment being performed.
