Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
When DNA replication occurs, the DNA strand is being unwound, causing the DNA to be overwound tightly past the replication fork.
For example, If you have ever wrapped two strings around each other and then tried to pull part the middle of the string while holding the ends tight, the rest of the string past the place you're pulling the string apart becomes very tight and strained.
Topoisomerase is an enzyme that binds to the DNA and helps release some of that strain by unwinding the DNA past the replication fork.
That means the correct box is the leftmost one. Hope this helps:)
Answer: it is a cation (a positively charged ion). its charge is (+). It will have one positive charge.
Explanation: Ions are charged atoms. Ions can be positively charged or negatively charged. A positively charged ion is called a cation while a negatively charged ion is called an anion. Cation is formed when an atom loses one or more electrons while an anion is formed when an atom gains one or more electrons. Normally, an atom has no charge that is, it is neutral because an atom always have equal number of protons and electrons. Protons have positive charge while electrons have negative charge. For instance when atom which have 8 electrons and 8 protons loses one electron, it will then have 7 electrons and 8 protons, thereby making the atom to have a positive (+) charge.
Answer:
QTL or Quantitative Trait locus
Explanation:
QTL or Quantitative Trait locus are chromosome sequences in which multiple genes contribute to a quantitative trait.
QLT is a locus that correlates with variation of quantitative trait in the phenotype of the population of an organism. It is an statistical method that links two type of information phenotypic and genotypic data in an attempt to explain the genetic variation in complex trait.
