How exactly do The answers to these questions are DNA replication and protein ... Wilkins amp Franklin Used X Ray crystallography to take pictures of DNA. ... DNA 39 s unique structure enables the molecule to copy itself during cell division. ... Much like a spiral staircase it has two single strands that join and twist together.
Explanation:
The correct answer is - A. larger and more rounded.
The modern humans have brain that significantly differs in size, but also in shape, compared to the brains of the hominid ancestors. The brain of the modern humans is larger, by far, and also it is more rounded and better developed, which has also led to the bone structure of the head to be more rounded. The brains of the hominid ancestors were smaller, but also more flattened, which can also be easily seen by the structure of the skull, more elongated and flattened.
It has differences between one ancestor and another, because as the evolution was going, every next ancestor in the line had slightly larger and slightly more rounded brain, so the difference is bigger with the older ancestors, and smaller with the more recent ones.
Answer:
They perform checkpoints and regulate/control the cell cycle.
Explanation:
Cyclin/CDK complexes are known to regulate both mitotic and meiotic cell cycles. Some processes are shared by both forms of cell division, however the process known as meiosis differs in terms of its features and needs. Following two rounds of cell division in succession, meiosis is characterized by the replication of DNA.

Answer:
There are no options to this question, however, the question can be answered. The answer is:
FF and FF/Ff
Explanation:
This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.
According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
