For a non-technical introduction to the topic‚ see Introduction to genetics. For other uses‚ see DNA (disambiguation). The structure of the DNA double helix. The atoms in the structure are colour-coded by element and the detailed structure of two base pairs are shown in the bottom right. The structure of part of a DNA double helix Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses

Developmental Biology Final Exam Study Guide 12/3/11 Part I Chapter 1 -Basic Problems of developmental Biology: • Maintenance of complete genome while cells differentiate -Main mechanisms of differential gene expression-polarity and cytoplasmic differences; polarity: • Gene expression leads to a difference in cells • Every cell in body has the same genome • Gene regulation occurs: o Polarity and cell division ▪ Uneven egg contents ▪ Environmental factors
Premium Developmental biology Cellular differentiation
Stem cells -are biological cells found in all multi cellularorganisms‚ that can divide (throughmitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals‚ there are two broad types of stem cells: embryonic stem cells‚ which are isolated from the inner cell mass of blastocysts‚ and adult stem cells‚ which are found in various tissues. In adult organisms‚ stem cells and progenitor cells act as a repair system for the body‚ replenishing

multiplication process of these viruses lie in how MRNA and viral RNA are produced. The sequence is as follows (1 and 2) are: Entry‚ uncodeing the viral DNA/ RNA (replication). (3) Transcription of a portion of the viral DNA. Translation follows (resulting enzymes) for multiplication of DNA/RNA. Most cases of DNA viruses early transcription is carried with the host transcriptase (some types of RNA carry their own transcriptase.) (4) Then translation of the “late” viral gene occurs. (5) Synthesis of capsid proteins

1. Taxol its generic name being palitaxel stabilises cytoskeletal microtubes and thus spindles cannot be formed so cell division is prevented. During telophase taxol causes the reversal of prophase events such as the chromosomes decondense‚ spindle disassembly‚ nuclear envelope reformation‚ the Golgi apparatus and E.R. reform and the nucleus also reforms. Cytokinesis effects are that the cell still divides for animal cells a cleavage furrow made of actin and myosin II constricts the middle of the
