Answer:
e. None of these
Explanation:
The immune deficiency viruses (HIV) are retroviruses that use a reverse transcriptase (RT) enzyme to produce a single-stranded DNA (ssDNA) from an RNA template. The reverse transcription allows retroviruses to replicate their genetic material, which is integrated into the host's genome as a double-stranded linear DNA molecule in a similar way to the mechanism of insertion used by endogenous retrotransposons. The synthesis of DNA is started by cellular tRNAs (tRNA3Lys) that are packaged into the virion. After reverse transcription, the HIV DNA enters the nucleus of CD4 immune cells (also known as CD4+ T cells), and then it integrates into the genome to coopt the host's cell machinery for its own replication.
Recombinant DNA is a type of artificial DNA which have genes that are taken from different organisms. During this process, a gene is take from one organism and putting the gene into another organism. Basically, the technology follows cut and paste scheme to form the new brand of DNA.
So to conclude this the technology cuts part of the DNA out to create a new DNA so you are cutting and pasting new DNA which is incredible.
Hope this helped.
THE QUESTION WILL BE <span>Are you likely to find zooplankton in the aphotic, benthic zone of an ocean?.... because if that's the question and there are chooices
</span>a. Yes. Zooplankton are chemosynthetic autotrophs.
b. Yes. Zooplankton can photosynthesize in the dark.
c. No. Zooplankton feed on phytoplankton and phytoplankton cannot photosynthesize in the dark.
<span>d. No. Zooplankton cannot chemosynthesize in the dark without the presence of oxygen in the water.
</span>THE CORRECT ANSWER WILL BE C
Answer:
Fluid lava (which is less viscous because it has less silica content) flows much further than viscous lava (that is high in silica content). Therefore, this types of lava forms shield volcanoes – low slopes and low height- because they flow over longer distances before they cool. Viscous lava from composite volcanoes that are high in height and have steep slopes.Explanation:
