The role of 3tc in inhibiting hiv reproduction is to interfere with enzyme trancriptase since it has a similar shape to the c nucleotide of DNA.Reverse trancriptase pick up 3tc molecule which led to termination of DNa further thus block reproduction of HIV.
The best description of expression gene process is constitutive. this is because it is the partial diploid strain whereby the strain containing a beta-galactosidase gene which is constitutive.
Gene expression process is the process by which information from a gene is being used in the synthesis of the functional gene product. The process gene expression is used by different known life. For example, we eukaryotes, prokaryotes and utilized by viruses which are used to generate the macromolecular machinery which is for life.
Answer:A culture or growth medium
Explanation: A culture or growth medium contains essential nutrients that aids in the growth of microorganisms. A culture medium can be in liquid form or solid form. It is very important to make sure that a culture or growth medium is sterile and free from any form of contamination. The main function and importance of a culture or growth medium is to ensure that microorganisms grow in a sterile environment that has all the major and essential nutrients required for their growth and to preserve them against any form of harm or contamination such that when these organisms are needed they can be used.
Answer: The correct answer is D) Replication creates new DNA while transcription creates mRNA.
Replication is a genetic process in which DNA ( deoxyribonucleic acid) is duplicated so that two copies of the genetic material is prepared. This is important for cell division.
Transcription is a process, which includes copying of the genetic formation from DNA into mRNA ( messenger RNA). This provides instructions for the synthesis of specific proteins.
Thus, the correct option is D)
