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:
Carry dissolved blood gases
Explanation:
Haemoglobin is a protein usually found in the red blood cells and is said to be what give the blood its characteristics red color.
Haemoglobin is a protein that also contain some iron atoms which binds oxygen; a gas to itself and aid in the transport of oxygen from the lungs in some group of animals and gills in others to the rest of the body allowing for aerobic respiration to occur in the body.
The right answer is He is studying oxygen, which can also be found in proteins.
Carbon atoms could also be a right answer if there was a statement...
Sugars, composed only of carbon atoms, hydrogen, and oxygen, are the simplest energetic nutrients. Example to (C6H12O6): If we look at the chemical formula for glucose, we can see that the proportion Hydrogen / Oxygen corresponds to that of water (H2O)
Lipids also consist of carbon atoms (C), hydrogen (H) and oxygen (O), but fatty acids are molecules that are low in oxygen. Example: Linoleic acid C18H32O2
B. being able to continue for a long time
Answer;
B) increased number of chromosomes in the offspring.
Explanation;
-Cross over is a process that takes place during meiosis. It occurs when homologous chromosomes pair up and the segments of chromosomes are exchanged between non sister chromatids, resulting to recombinant chromosomes.
-The process causes genetic variation among organisms due to exchange of genetic material. In addition to increased genetic variation, cross over may results to the appearance of new phenotypes in the offspring. Also cros-over mutations may cause harmful mutations.
