Answer:
The correct option is A, since if the DNA enters in a circular form it is called a plasmid, and the plasmids upon entering the bacteria self-replicate outside the genetic structure, which gives the bacteria better survival qualities.
Explanation:
Plasmids are generally circular extrachromosomal DNA molecules that replicate and transmit independently of chromosomal DNA, and are normally present in bacteria, archaea, and sometimes in eukaryotic organisms such as yeast. Its size varies from 3 to 10 kb. The number of plasmids can vary, depending on their type, from a single copy to a few hundred per cell. Plasmid vectors allow cloning of exogenous DNA ligands of up to 4 kb since a larger size than this makes cloning in these vectors difficult. The term plasmid was first introduced by the American molecular biologist Joshua Lederberg in 1952. Plasmids can only coexist as one or more copies in each bacterium, due to cell division they can be lost in one of the secreted bacteria.
Enzymes speed up chemical reactions within the body, including reactions in metabolism
Answer:
Explanation
Given that 36% are recessive in traits
100-36 = 64% for dominant traits considering a whole population to be 100%
P=dominant allele
q= recessive allele
P2= dominant genotype
q2= recessive genotype
according to hardyweinberg principle, p+q=1
64/100= 0.64 frequency for dominant traits or genotype, therefore
p2=0.64
then
P=√0.64
p= 0.8
Therefore, dominant allele frequency (p) for the population is 0.8
The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. Hope it helps
