Answer: The correct complementary DNA sequence for the given sequence is D. TAG-CAG-GGT.
DNA contains nucleotide pairs on a sugar phosphate backbone. The nucleotide pairs are connected by hydrogen bonds and each nucleotide pairs with only one other nucleotide. The bases are of two types: purine and pyrimidine. The purine bases bond only to pyrimidine bases. The base pairing follows Chargaff’s rule where adenine forms a pair with thymine by two hydrogen bonds and Guanine forms a bond with cytosine with three hydrogen bonds between them.
Answer:
b) an ancestral cell most likely engulfed and aerobic prokaryote in a relationship that proved beneficial for both cells
Explanation:
The evolution of mitochondria occurred when a prokaryotic ancestral cell engulfed an aerobic prokaryote. This aerobic prokaryote had the ability to perform aerobic respiration. The symbiont was sustained in the ancestral cell as the association was beneficial to both of them. The ancestral cell could drive a large number of ATP by aerobic respiration.
Gradually, symbiont lost the ability of free survival and led to the evolution of mitochondria. The presence of circular DNA and ribosomes in mitochondria similar to the prokaryotic cells prove their origin by endosymbiosis.
Answer:
Because lactose intolerance isn't a disease, it just mean the individual's stomach isn't able to digest the lactose found in milk.
Explanation:
Food molecules contain chemical energy which is released when its chemical bonds are broken.
Food undergoes digestion in the digestive system and is broken down into its monomer units. Carbohydrates, which are the principal source of energy, are broken down into glucose. Glucose is the monomer unit of carbohydrates.
Glucose then is taken up by cells and is used in cellular respiration, which involves three main stages namely glycolysis, Krebs cycle and the electron transport chain, through which a glucose molecule is processed to form at least 36 molecules of ATP.
ATP is the form of energy that cells use.
None of the above because those are all apart of the photosynthesis equation.
