The excretory system will help remove extra water and eliminate it as urine.
Answer:
The STR fragments will have different size for different animals.
Explanation:
- STR means Short Tandem Repeats.
- STR forms the genome's microsatellite region.
- STR or microsatellite is that region of the genome where, about two to seven base pairs of the DNA (for example, ATGATGATGATG), are repeated for multiple time. Such sequences can have few hundred repeats.
- While replicating these micro-satellite regions, the accuracy of the DNA polymerase in proof-reading the sequence of the newly synthesised strand, decreases, due to the multiple repeats.
- As a result of this, the DNA polymerase either adds more or adds less of such repeated sequences as compared to the parental DNA sequence. This results in generation of polymorphism (different microsatellite size in different individuals) in the repeat regions.
- Due to difference in size of the STR in different individuals, the size of the fragment amplified through PCR will vary for different elephants.
I can help you with me if you tell me which trait is dominant and which trait is recessive.
Answer:
<u>Louis Pasteur</u>
Explanation:
Although louis was a great scientist who made contributions to the cell theory postulating that cells come from preexisting cells, he was a renowned and father of microbiology. He proved that diseases are caused by microorganisms, developed the first vaccine and provided logical ground knowledge on fermentation and brewing.
Answer: 1,2 and 3.
The following are common to transformation, transduction and conjugation.
1. Unidirectional transfer of genes.
2. Incomplete gene transfer.
3. Homologous recombination.
Explanation:
Transformation is the taking up of free DNA from the environment.
Transduction is the transfer of DNA by bacteria to a viruses.
Conjugation is the transfer of Plasmid or circular DNA through a tube between the cells. Incomplete DNA are transferred unidirectional .
