The physical appearance of the biochemical characteristic of an organism as result of the interaction of phenotype; some mutation has the positive effect on the organism in which they occur.
<u>Explanation:</u>
They are called beneficial mutation. Phenotype of the organism lead to new development of proteins which help the organisms to adopt their own environment. Beneficial mutation are essential for evaluation to occur.
Phenotype stretch the DNA without any function; the mutations occur in a protein coating region, but it end up the process by not affecting sequence of the protein.
Example of phenotype are:
Observable characteristics including behaviour, biochemical properties; the phenotype benefits such as HIV resistance, lactose resistance.
Answer:
Without fungi in the forest, dead and rotting materials would not be broken down. Dead plants and animals would be piled up in the forest.
That's the exact answer. I promise!
hope this helps! :)
1. Nucleic acids are the molecules that code the genetic information of organisms.
2. The two nucleic acids used in the repair, reproduction and protein synthesis are deoxyribonucleic acid (DNA, shown) and ribonucleic acid (RNA)
3. DNA and RNA are polymers made up of monomers called nucleotides
Answer:
x= 0, y = 2
Explanation:
4x + 5y +2 = 12
Let's suppose that
x = 0
y = 2
By putting the values of x and y
4(0) + 5( 2) + 2 = 12
0 + 10 + 2 = 12
12 = 12
Hence, it is proved that x = 0 and y = 2
Answer:
d. transcription factors
Explanation:
Transcription factors are the proteins present in cells that are involved in the regulation of gene expression. The transcription factors may increase or decrease the expression of a gene. Therefore, a transcription factor may serve as an activator or repressor for a gene. These proteins bind to a regulatory sequence present near or within a gene, interact with RNA polymerase or other transcription factors and thereby, affect the transcription initiation.
Since binding of dioxin to certain proteins alter the pattern of gene expression in the cells, these proteins are the transcription factors. For instance, dioxin may bind to a transcription factor and up-regulate the expression of genes which in turn regulate the cell division.
