Which of the following is homozygous dominant? a AA b Aa c aa
GarryVolchara [31]

Answer: a). AA

Explanation: Every trait is controlled by at least a pair of gene. Genes have different forms known as alleles. Alleles can be dominant or recessive. A dominant allele expresses itself in the presence of a recessive allele and masks the effect of a recessive allele. A recessive allele cannot express itself in the presence of a dominant allele and it's effect is masked by a dominant allele. Dominant alleles are usually written in upper cases such as A, T, while recessive alleles are usually written in lower cases such as a, t. The two alleles that determines a trait is called a genotype. A genotype can be homozygous if the two alleles are identical such as in AA or aa

and can be heterozygous if the two alleles are not identical such as in Aa, Tt.

What is the difference of Theology and Biology?
Alona [7]

Answer:

Science is a system of body of knowledge that contains established truths based on observation of facts by empirical means, collection of such data, theorizing on that basis, do experiments on the data, repeat the experiments under different data of similar nature, once confirmed, make it a law.

So you can define science as logical construction of empirical data. The principles involved is the principle of verifiability, confirmability, conformability and falsifiability. Science is always opne and subject to correction by new observations. If there is a dispute between a Law already established and a new observation, the new observation will replace even the law for rejection or modification.

Theology is a study of God, beliefs and the relationship between God, universe, our knowledge and man's link with all these issues. It is  a rational way of studying religious ideas. For example, we talk about Christian theology. It is more concerned with our beliefs mostly unquestionable in principle. they are more like axioms. You can say that they are self evident truths which do not require any proof.

Explanation:

Theology can use the principles and methodology of science to establish some of its tenets. But generally, theologians claim that their system falls outside science and it is supra science and science is too little or limited  with its rusted tools to examine and verify Theological doctrines.

Science does not need theology nor the other way round, but man needs both. 60% of the total population believe in god and 40% are non-believers in the sense some are irreligious and some are anti-religious and some NOTA category. But all of them, in some sense, get some "religious" anxiety, when during a flight take off, if there is turbulence at the tail end of the flight!

Where does the helicase start unzipping
Ivenika [448]

answer: It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA. This 'unzipping' of the molecules will expose the nitrogenous bases of the nucleic acid chain so that new nucleotides can be added to create the daughter strand.

Explanation: hope this helps
