I think that the answer is C- "I RNA contains uracil and ribose." because it is the one that mostly makes sense and is the one that most shows the difference between RNA from DNA.
According to google: "Ribonucleic acid (RNA) is a polymeric molecule implicated in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with proteins and carbohydrates, constitute the three major macromolecules essential for all known forms of life."
I hope this helped!

Explanation:
DNA typing is the forensic analysis of genetic information from a biological sample as an aid to identification.
Answer:
because cells build tissues, tissues build organs, organs build organ system.
Answer:
In the given case, it can be concluded that very less amount of telomerase is being produced.
Explanation:
Terminal transferase or telomerase refers to a ribonucleoprotein that supplements a telomere repeat sequence to the 3 prime terminals of telomeres. A telomere is present at each terminal of the chromosomes found in the majority of eukaryotes. It helps in safeguarding the terminals of the chromosomes from destruction or from getting combined with the adjacent chromosomes.
Telomerase has its own RNA molecule and works as a reverse transcriptase enzyme. Generally, telomerase is found active in gametes, in stem cells, and in the majority of cancer cells, however, it is generally present in low concentration or is absent in the majority of somatic cells. Thus, the decrease in the ends of the chromosomes suggests that the production of telomerase is taking place at low levels.
