Answer:
Phosphorylation
Methylation
Explanation:
Histone mobilization deals with the covalent bonding of several functional groups to the free nitrogens in the R-groups of lysine in the N-terminal tail.
DNA transcription can be controlled or altered via 'methylation' on the histones. Methylation is the mode of transferring methyl group to amino group of histone proteins that form the nucleosomes, which result to chromosomes formation through wrapping of DNA double helix around it. Histones methylation can either increase or decrease genes transcription. Chromatin modification is known to stimulate neural pathways that are essential for long memories and learning.
Histones phosphorylation is associated transcriptional activation. It deals with the transfer of phosphate group to amino acids of the proteins. Phosphate group known to be negatively charged, when transferred to amino acids of the histone proteins, it creates a repulsive force with the negatively charged phosphates of the DNA backbone. It can occur in serine, tyrosine and threonine. The enzymes kinases activate phosphorylation, while protein phosphatases remove phosphate groups.
Answer: the cars run on pure solar electricity and are driven by motors so there is no use or out put of gasoline of any kind
Explanation:
Answer:
Before the advent of modern biology, study of life and organism was in the realm of natural philosophy and was never in the club of classical sciences like physics, chemistry and engineering. Today biology is a science that studies life and living organisms.
Explanation:
A biologist can be categorized as a scientist because all the processes that supports scientific investigations are carried out in the study of biology- data collections, critical thinking, observation and collection of result for the purpose of public consumption.
On the other hand forensics is the mainly the aplication of science-mostly biology- in resolving criminal activities. It involves the collection of samples, anaylsing and presentaion of result for decison making.
An example of an adaptation
Answer:
0.9342
Explanation:
The Hardy-Weinberg equation states that p² + 2pq + q² = 1,
where p is the frequency of the dominant 'normal' (n) allele and q is the frequency of the recessive 'albino' (a) allele in the population, while q² represents the frequency of the homo-zygous albino genotype (aa), p² represents the frequency of the homo-zygous normal genotype (nn) and 2pq represents the frequency of the heterozygous genotype (na).
In this case, the frequency of individuals in the population that have the genotype aa (q²) is equal to 26/6000 = 0.004333. In consequence, q is equal to √ 0.004333 = 0.0658.
Moreover, the allele frequency of the normal (n) allele p is equal to 1 - q = 1 - 0.0658 = 0.9342, so p² (nn) = (0.9342)² = 0.8727.
Finally, the frequency of the heterozygous genotype (na) is 2pq = 2 x 0.9342 x 0.0658 = 0.123.
