You have obtained genome nucleic acid from a sample and have determined the base content. Please identify the genome structure f
or the following sample. State - if the genome is RNA or DNA - if is likely to be single-stranded (ss) or double-stranded (ds) - if it could be from a eukaryote and/or prokaryote and/or virus. 27% G; 23% A; 27% C; 23% T
The genome is double stranded DNA molecule from a eukaryotic organism.
Explanation:
DNA is present as genetic material in all the living organism except some viruses. Viruses may contain DNA or RNA as their genetic material and has the ability to convert RNA into DNA.
The DNA contains 27% G; 23% A; 27% C; 23% T. This DNA follows the Chargaff's rule in which the amount of purines is equal to the amount of pyrimidine. Adenine is paired with thymine and both contains 23% of DNA. Guanine is paired with cytosine and both contains 27% of DNA. The genome is DNA as thymine is present and not uracil. This is double stranded DNA from the eukaryotes only.
Plants perform photosynthesis and cellular respiration.
Explanation:
Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.
