A segment of DNA that codes for RNA, and can vary in length from a few hundred to as many as two million base pairs in length be
klasskru [66]

We can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.

<h3>What is a gene?</h3>

To expand on the definition given, we can say that a gene is, as mentioned, a series of base pairs known as nucleotides that will code for RNA. The RNA in question is messenger RNA that will later become a protein. Through this process, genes code for every aspect of an organism and will determine its morphology and all other biological aspects.

Therefore, we can confirm that a segment of DNA that codes for RNA and can vary in length from a few hundred to as many as two million base pairs in length best defines a gene.

Regnier de Graaf and his followers believed that traits are inherited from mothers.
mojhsa [17]

Answer:

True

Explanation:

  • Regnier de Graaf was one of the most prominent scientists and physicians of the 17th century. He made significant contributions to reproductive and anatomical research.
  • Regnier de Graaf initially thought that ovarian follicle was the egg itself.
  • Under the misconception that the egg itself travels to the uterus through the fallopian tube, de Graaf also proposed a new theory of sexual reproduction, the ovist theory, that stated that the spermatozoa or the sperm contains the "spirit of life" that it infuses into the egg.
  • The <em>ovist </em>theory is one of the forms of preformationism, the other being the <em>spermist </em>theory. Both of these regard the egg or the sperm to be containing the "spirit of life" or the embryo.
  • His discovery of the ovarian follicle (known as Graafian follicle) that ruptures to release the egg later changed his point of view.
