<h3><u>Answer;</u></h3>
Nucleotides are the sub units of DNA, their function is to form the genetic code.
<h3><u>Explanation</u>;</h3>
- Nucleotides are the subunits of DNA. The four nucleotides are adenine, cytosine, guanine and thymine.
- <em><u>Each of the four bases has three components, a phosphate group, a deoxyribose sugar and a nitrogen-containing base.The four different nucleotides in DNA differ only in the nitrogenous base. The nucleotides bind together in specific pairs , adenine with thymine and cytosine with guanine.</u></em>
- The function of nucleotides is to build DNA. The way they bind leads to the characteristic double helical structure of DNA. The order of the different nucleotides forms the genetic code.
Answer: C
Explanation:
In substrate level phosphorylation energy is trapped directly from the substrate, without the help of the complicated electron transport chain reactions.
Substrate-level phosphorylation refers to the formation of ATP from ADP by directly phosphorylating ADP from a high energy substrate catalyze by an enzyme.
But when energy is trapped by oxidation of reducing equivalents such as NADH, it is called oxidative phosphorylation.
Examples of substrate level phosphorylation in glycolysis include conversion of 1, 3-Bisphospho glycerate to 3-Bisphospho glycerate and conversion of phospho enol pyruvate to pyruvate
Bacteria is not included as an abiotic factor in an ecosystem.
