The restriction enzymes of bacteria protect the bacteria from successful attack by bacteriophages, whose genomes can be degraded
by the restriction enzymes. The bacterial genomes are not vulnerable to these restriction enzymes because bacterial DNA is methylated. This situation selects for bacteriophages whose genomes are also methylated. As new strains of resistant bacteriophages become more prevalent, this in turn selects for bacteria whose genomes are not methylated and whose restriction enzymes instead degrade methylated DNA. The outcome of the conflict between bacteria and bacteriophages at any point in time results from ________.
Frequency-dependent selection can be determined in a variety of ways, which are not different, yet all convey the feeling that the wellness of a phenotype or genotype changes with the phenotypic or genotypic structure of the population. Such determination can promptly keep up phenotypic variety and hereditary variety at a solitary locus. The support of polygenic variety with recurrence subordinate determination are to some degree more prohibitive than in the single locus case
Utilizing a recreation model, Mani et al. (1990) investigated the consolidated impact of change, balancing out ward choice, and recurrence subordinate determination on a hereditary framework in which there are n (≤12) loci, each with up to 32 alleles that demonstration additively, the i allele contributing an amount I to the genotypic variation
Hence, the right answer for the fill up the blanks is "Frequency-Dependent Selection"
Intrasexual Selection is when
members of the same sex within a species contend emulously with each other in
order to acquire chances to mate with others such as the male against male
competition for females. This type of selection often involves posturing and
fighting. Species or individuals suitable for intrasexual selection will possess
developed better weapons than their competitors.
Poverty is the root of all evil in this situation along with gendder discrimination. Because of the social unpopularity regarding females and because many women lie below standard income, they simply cant afford or just refuse to have kids.
The RNA codon will be GAU, pairing Cytosine-Thymine-Adenine DNA codon with Guanine-Adenine-Uracil RNA codon. This codon is the Amino Acid, Aspartic Acid. In this codon we see Uracil which is the counterpart of Thymine in the RNA.
