1. Describe two characteristics or features that make prokaryotic and eukaryofic cells similar to each other. At least one of th
Tcecarenko [31]

Answer:

1.The group of organisms with cells which contain of nucleus and other membrane bound organelles are called Eukaryotes. These organisms have their DNA arranged in the chromosomes, bounded by histones proteins. They have diversity of forms, thus they can be colonial, unicellular or multicellular in forms. Their cells reproduced by mitosis and meiosis for gamete formation.  

Reproduction can be sexual and asexual. Their ribosomes are found in the cytosol, and they are larger than that in prokaryotes, but ribosomes in chloroplast and mitochondria are similar as that in the Prokaryotes (70s). Plants and complex animal cells are examples.  

Group of unicellular organisms which lack membrane bound nucleus, and other organelles, are called Prokaryotes. Their two domains are the bacteria and archaea. They reproduce asexually only, by fusion of gametes. Due to lack of membrane bound organelles, their water soluble components and cellular inclusions (metabolites and DNA) are found in the cytoplasm bounded by the cell membrane.  

<u>When viewed under microscope. Prokaryotes are similar to Eukaryotes as follows. </u>

Approximately 90% of human cancer cells exhibit significant levels of telomerase. Does this mean that telomerase is an oncogene?
alukav5142 [94]

Answer:

No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.

Explanation

telomerase is not responsible for causing  deregulation while oncogenes cause deregulation .

Telomeres length shorten after the cell division which stops them to divide again and cell die.

Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could  prevent senescence.
