Answer is thousands of different proteins
Proteins are macro-molecules, made up of small units or building blocks. These building blocks are called amino acids. To build a protein, first the amino acids are connected into long chains, called polypeptide chains. These chains of amino acids fold into all types of shapes. Some chains fold into spirals. Combining these spirals, sheets, and loops is how the three-dimensional shape to build a functional protein. The human body uses just 20 amino acids to make all the proteins it needs to function and grow. Because amino acids can be arranged in many different combinations, it's possible for our body to make thousands of different kinds of proteins from just the same 20 amino acids.
To be considered a living thing an organism must be able to - that the organism was composed of cells (either 1 or many)
<span>- that the organism had a genetic molecule and was able to evolve (DNA is the base-unit of evolution) </span>
- that the cell/s of the organism was/were enclosed by a cell membrane (life is self-contained)
<span>- that the organism was able to carry out its own, self-contained, biochemical reactions </span>
- that the organism was able to reproduce, grow and develop (pass its genetic molecule onto a future generation)
<span>- that the organism was able to respond to its environment (either from a sensory, neurological or evolutionary way)</span>
Considering the answers
A. GTT
B. TCT
C. TCC
D. GCA
The answer would be A. GTT
A sequence of amino acids in a protein determines its functions. The DNA sequence of a gene determines the amino acid sequence of the resulting protein, therefore, any changes in DNA sequences can result in changes in protein function.
