In Phaeophyceae: Sexual reproduction may be isogamous, anisogamous or oogamous. Union of gametes may take place in water or within the oogonium (oogamous species).
3 Molecular Basis of Inheritance
Each colony is collection of bacteria having many copies of DNA fragment called 1) Splicing 2) plasmid 3) Gene Cloning 4) Replicon
4
The process by which DNA of the nucles passes information to RNA is called
1) Translocation2) Transcription3) Translation4) Tranportation
5
The presence of DNA is important for cellular metabolic activities because DNA
Enzymes are necessary for most chemical reactions that occur in our bodies. DNA controls the production of proteins, of which enzymes are an example of, in a process called protein synthesis.
