Concepts in anatomy from the given options include:
- The brain is composed of two hemispheres.
- Each kidney contains approximately 6-10 pyramids.
- The muscle on the back of the arm has three heads of origin.
- Study of form.
<h3>What is anatomy?</h3>
Anatomy is a branch of biology that is concerned with the study of the structure of living organisms and their various parts.
Anatomy studies the position of body structures as well as the position of related structures or organs of the body.
Anatomy also studies how the structure of these body parts relates to their functions.
Therefore, concepts in anatomy from the given options are:
- The brain is composed of two hemispheres.
- Each kidney contains approximately 6-10 pyramids.
- The muscle on the back of the arm has three heads of origin.
- Study of form.
In conclusion, anatomy deals with structure of body parts of living organisms.

This is because the GP120 protein
of the HIV virus that forms the ‘knob’ is
essential for the infection of CD4 cells
of the immune system by the virus. The glycoprotein is, therefore, a good
target for vaccines especially since the
molecule is highly conserved because most mutations in the region could be highly deleterious to the virus.
DNA is nothing more than a sequence of bases (nucleotides) and since DNA is normally double stranded, they can be referred to as base pairs. One could best visualise it like a zipper: two connected strands (that can also be separated). DNA is made up of only four different bases, abbreviated as A, C, G and T. These always form the same pairs: A on one side of the zipper, T on the other side and the same goes for C and G. So, when unzipped, you always know the sequence of the opposite strand.
The sequence of base pairs that make up our DNA should be viewed like a bar code. Every set of three bases code for one building block of a protein. That's all that DNA is for: code for building proteins. A set of three bases is called a codon and tells machinery in the cell (ribosome) to add one specific building block to a forming protein. It's like Lego and DNA is the instructions that tell you which block to add next.
These different blocks give shape and function to the proteins it helps to build.
