A basic event in reproduction is the creation of a DUA copy. Cells use chemical reactions to build copies of their DUA. This creates two copies of the DUA in a reproducing cell, and they will need to be separated from each other. However, keeping one copy of DUA in the original cell and simply pushing the other one out would not work, because the copy pushed out would not have any organised cellular structure for maintaining life processes.1. The DNA in the cell nucleus is the information source for making(i) proteins(ii) cellulose(iii) acids2. Full form of DNA is(i) Deoxyribo Nucleic Attack(ii) Deoxyribo Nucleic Acid3. DNA copying is accompanied by the creation of an additional cellular apparatus, and then the DNA copies separate, each with its own cellular apparatus. Effectively, a cell divides to give rise to two cells. These two cells are (i) identical(ii) similar4. The consistency of DNA copying during reproduction is important for the maintenance of body design features. True or false ?(i) TRUE(ii) FALSE5. Organisms look similar because their body designs are similar. If body designs are to be similar, the blueprints for these designs should be similar. True or false ?(i) TRUE(ii) FALSE |
