The earliest forms would be plants and other life like that, and current day would be mostly humans and animals and a lot of plants are disappearing
<span>Biotechnology is the use of biological processes, organisms, or systems to manufacture products intended to improve the quality of human life. Just a tip its fairly easy to find most of the USA test prep vocab on quizlet if you dont know them. [I got the definition and answer from Quizlet]</span>
Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.
<h3>What is DNA?</h3>
All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.
The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.
The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.

Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
Explanation:
Mutations. Point mutations are in a single DNA base pair; insertions and deletions are where a piece of DNA is removed, or added to, a gene, respectively.
