The cytoskeleton has many functions. It is made up of different types of proteins that combine to make different types of filaments. The cytoskeletal filaments are dynamic, meaning they can grow and shrink at different parts of the cell and at different rates.
1 Another method of genetic transfer and recombination is transduction. 2  This method involves the transfer of DNA from one bacterium to another with the use of a bacteriophage (phage). 3  A phage is a virus that infects bacteria.
An organism's genetic information is encoded as a linear sequence of bases in the cell's DNA. During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein.RNAs also play important roles in protein synthesis, as will be discussed in the ribozyme section, as well as in gene regulation.roteins are the workhorse of the cell and carry out diverse catalytic and structural roles, while the nucleic acids, DNA and RNA, carry the genetic information that can be inherited from one generation to the next.
