Are used for main source of energy: carbohydrates
Answer:
Bacteria
Explanation:
Bacteria are a group of single celled organisms that are neither plants or animals.
Bacteria lack cell organelles such as the nucleus and the chlorophyll.
They can be found in many environments and most of them are adapted to survive in extreme environments such as hot-springs where the temperatures are extremely high.
Unlike the plant cell wall, bacterial cell wall has a layer of peptidoglucan which determines their shape. Their cytoplasm contains both DNA and RNA.
Answer:
D. changing the DNA of a living thing to change its characteristics.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits.
Answer: They are the stop codon
Explanation: At the end of and mRNA squence there are three nucleotides that tell the ribosome to end the protein being made.
