Aerobic Respiration :))
Hope this helps
***the molecular tools are:
Restriction enzymes
Restriction genes allow the synthesis of DNA-cleaving endonucleases at very specific sites to digest parasite DNA
-RNAse
* RNA A: specifically cleaves single-stranded RNAs, and releases residues of pyrimidine 3'-phosphates
* H RNA: cleaves DNA / RNA hybridization -digests RNA in an RNA-DNA complex. It is used to remove RNA after making a first strand of cDNA using reverse transcriptase.
-Alclaline phosphatase:
Alkaline phosphatases are active at alkaline pH. They make it possible to remove the phosphate group situated at 5 'of a DNA chain. They are extracted from bacteria or animal origin (intestines). They are used to prepare recombinant DNA.
-Kinase:
Kinases make it possible to fix a phosphate group in the presence of ATP.
-the enzymes copying the nucleic acids:
* DNA Polymerase (Taq, and the Klenow fragment) for example)
* inverted transcriptase.
* RNA polymerase
-Ligase
***Use of these techniques.
The biologist has a number of tools and methods for studying gene mutation. The analysis of the gene will make it possible to diagnose certain pathologies. Then, once the pathology is known, the doctor can establish an adequate treatment for the patient in order to treat it.
The answers are; geographical isolation and temporal isolation.
In temporal isolation, because the different species have different mating seasons, so even though their habitats overlap, they do not interbreeding is rare. Geographical isolation also plays a role because the different species are found predominantly in different sites during breeding, some in the woodland, some in the lowlands and others in streams.
Cross pollination is the transfer of pollen of different species to stigma of different species of plants.
Cross pollination results in healthy, viable and diverse plants.
Mendel observed that traits could either be dominant or recessive.
Blended traits or incomplete dominance is the condition in which dominant allele could not produce its trait alone instead blending with recessive allele takes place giving new phenotype to progeny.
Explanation:
In cross pollination pollen transfer takes place from anthers to stigma. In Mendelian genetics the anthers of the plant was removed because it has both male and female parts on same plant so that self pollination does not take place.
The importance of cross pollination is that it creates diversity in the plant species since the traits having different alleles are combined to form the progeny plant. The offspring are healthier and high quality seeds are found.
Mendel observed that traits are either dominant or recessive in general. It was observed that when homozygous parents were crossed, the progeny in F1 generation always had dominant trait. The recessive trait only appeared when F1 generation offspring were self pollinate.
Blended traits or incomplete dominance appear when alleles get blended and exhibit the traits in phenotype. The phenotype appeared will not be matching with either parents.
The example is a white coloured flower is crossed with red colour flower the resultant colour of the flower is pink. It shows that dominant allele red is not completely dominant and gets blended with white colour.
