A. T-A-C-G-A-T
A and T pair together, and G and C pair together. There are no U’s because U’s are in RNA, not DNA.
Macrophages as they are versatile cells which reside in the tissue
Answer:
There are two possibilities: The offspring can either be HH or Hh; therefore, there is a 50% chance of the offspring being one of the two above. This means that there is a 50% chance off the offspring being tall or short.
Answer:
Cells are the smallest unit of life. This is true.
Cells are important to the structure and function of living things. This is true.
All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.
Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.
The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions which are described as so because their amino acid sequences can be different on different antibodies.
The specificity of antibodies is determined by the variable regions found at their endpoints. Antibodies are specialized proteins secreted by B-cells of the immune system. They are also called immunoglobulins. They contain four polypeptide chains that comprise two heavy chains and two light chains to form a Y-shaped molecule.
The variable regions, more specifically the hypervariable regions of an antibody, have a high ratio of different amino acids with the most common amino acids provided in one place. The variable region serves as the antigen-binding site while the constant region found below the variable region is determined to invade the antigen.
Antibodies are preserved in our body to identify the antigen the next time it encounters. They send the signals to the other body parts to reject the antigen and invade it.
