Answer:
this mutant will not be able to use lactose
Explanation:
The lac operon is a cluster of genes with the same promoter which are transcribed as a single messenger RNA (mRNA). The lac operon encodes different enzymes that are used by the bacteria to obtain energy from lactose. The LacI gene is required for producing a repressor protein that binds to the promoter of the operon in order to inactivate its transcription (i.e., by preventing RNA polymerase from binding). A mutation in this gene prevents from its binding to lactose and it becomes inactive to the Lac operon.
The answer is nucleic acid
Answer:
Bioprospecting can be described as a term used for the search of valuable biodiversity out of which valuable compounds can be made.
Biopiracy can be described as a term which is used for the exploitation of biological material from plants or animals while failing to compensate for it.
The ethical concerns of this bioprospecting is that we shall look into consideration that we do not exploit the Earth from the plants and animals species which are beneficial to us. The research practices done on these plants and animals may eradicate the wild type varieties of them.
The right option is; D)The DNA in eukaryotic cells is enclosed in the nucleus, while the DNA in prokaryotic cells is not separated from the rest of the cell’s contents.
Eukaryotic cells are cells that contain membrane-bound organelles such as mitochondria, endoplasmic reticulum with a definite nucleus. Examples of eukaryotes are plants, fungi, and insects. Prokaryotic cells are cells that do not have a true nucleus or any membrane-bound organelles. Prokaryotes include bacteria and archaea. In eukaryotic cells, the DNA is enclosed in the nucleus, while in prokaryotic cells, the DNA (a single chromosome) is located in an area of the cell known as nucleoid.
One of the differences between cambrian animals and precambrian animals was the appearance of Appendages such as antennae as Cambrian animals evolved
The antennal appendages will increase the sensing abilities of the animals
hope this helps
