Answer: N-terminal green fluorescent protein (GFP)
Explanation:
Protein synthesis takes place in ribosomes located in the cell cytoplasm, in which amino acids are transported by transfer RNA corresponding to each amino acid to the messenger RNA where they bind in the appropriate position to form new proteins. <u>The messenger RNA has a sequence of nucleotides that are translated into protein, as each codon (set of three amino acids) codes for one amino acid</u>.
Genes are the storage units of genetic information, so they are segments of DNA that contain the information on how the cells of the organism should function. Each gene codes for a protein, so if a gene is damaged or absent, the protein will not be obtained. In this case, mutant cells with a deleted gene, will round up and wont form their normal appendages. This mutation can be rescued or repaired with a gene that encodes an N-terminal green fluorescent protein (GFP) fusion of the protein. The N-terminal end is the amino-terminal end and it refers to the end of a protein that ends with an amino acid that has a free amino group. The C-terminus or carboxyl-terminus is the end of a protein that ends in a carboxyl group. The convention for writing peptides is to place the C-terminal end to the right and write the sequence from the N- to the C-terminal end. So, when an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, the gene will produce the protein with a GFP tag.
<u>GFP is Green Fluorescent Protein</u>, and it is a protein produced by the jellyfish <em>Aequorea victoria</em> t<u>hat emits bioluminescence in the green region of the visible spectrum</u>. When a gene is fused to another gene (at either the N- or C-terminus, although in this case it is the N-terminus), the entire messenger RNA is translated together as if it were a single fused protein. <u>Thereby, since the protein will be produce with a GFP tag, it can be seen under the microscope and it will be apropiate to use in studying cellular localization and activity.</u>
There are some considerations that this problem does not question, such as that there must be a start codon for protein synthesis and a stop codon, and this stop codon must not be in the middle of the gene or between the gene and the GFP tag.
Answer: Hypotonic
Explanation: If a plant is placed in an isotonic environment the plant will be limp, and if placed in a hypertonic environment, the plant will lose water.
Answer:
The options
a. prehistoric archaeologist
b.archaeologist
c. Paleoanthropologist
d. paleoprimatologist
The CORRECT ANSWER IS c.
c. .paleoanthropologist
Explanation:
a. Prehistoric archaeology❌
It is the study of the previous times before historical records were used or established. It examines all the pre-urban societies of the world. It possess some unique activities and processes for evaluating material remains so that archaeologists can 'rebuild its ecological settings.
b. Archaeology, or archeology❌
It deals with the study of human processes via the recollection and evaluating of material culture. Its archaeological record employs the use of artifacts, architecture, biofacts or ecofacts and cultural landscapes.
c. Paleoanthropologist✔✔✔
Is the study of the origins and predecessors of the modern day human species, with the aid of fossils and several remnant. It deals with the study of extinct individuals of the genus Homo sapiens via its fossil remains.
d. paleoprimatology ❌
It is the study of ancient (majorly extinct) primates.
Cutting down trees, building roads in mountains, constructing buildings and removing sediments from sidewalks using water does donate to increase the turbidity of water.
<h3><u>Explanation:</u></h3>
Turbidity of water is formed due to a suspension formation of water and the dust and dirt along with several insoluble particles. This turbidity is actually formed in nature due to erosion by water or wind which gets deposited in water. Removing trees or construction of road leads to loosening of ground soil which is easily washed away by water. Construction of buildings also results in cutting of trees. The washing of sediments with water also increases the chance of turbidity of water.
Answer:
Explanation:
One of water's most significant properties is that it takes a lot of heat to it to make it get hot. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1°C. For comparison sake, it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
