Dna is copied in a cell before a cell divides. Two nucleotide strands of original double helix separate along the strands. ... They move along the DNA molecule breaking the hydrogen bonds between the complementary nitrogen bases. Replication fork- y shaped region that results when two strands separate.

Describe the events that occur during meiosis that are defined by Mendel's laws of segregation and independent assortment. Expla
zysi [14]

Answer:

Mendel's Laws are a set of basic rules on the inheritance of characteristics from parent organisms to their children. They are considered rules rather than laws, since they are not fulfilled in all cases. Mendel's first Law of equitable segregation establishes that during the formation of the gametes each allele of a pair is separated from the other member to determine the genetic constitution of the filial gamete, the two alleles, which code for each characteristic, are segregated during the production of gametes through meiotic cell division. This means that each gamete will contain only one allele for each gene. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation. For each characteristic, an organism inherits two alleles, one for each relative. This means that in somatic cells, one allele comes from the mother and one from the father.

Explanation:

Mendel's laws reflect chromosomal behavior during meiosis: the first law responds to the random migration of homologous chromosomes to opposite poles during anaphase I of meiosis (both alleles and homologous chromosomes segregate equally or 1: 1 in gametes) and the second law, to the random alignment of each pair of homologous chromosomes during metaphase I of meiosis (whereby different genes and different pairs of homologous chromosomes segregate independently).Even though not all genes are inherited in the proportions described by Mendel, they are undoubtedly all inherited in the same way, that is, the alleles or different alternatives of a gene are separated in meiosis and each gamete will carry only 1 of them (2nd Mendel's Law) and in turn all genes on different pairs of chromosomes are transmitted independently. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation.Therefore, of each possible genotype for a two three or more genotypes it is possible to know how many gametes it will form, in what proportions and therefore predict results of crosses.

What is the solar process that results in the production of energy?
pentagon [3]

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

Marianna [84]

Answer:

Cardiac muscle tissue is a type of tissue due to which left ventricle is formed.

Explanation:

Heart is a main organ of human body due to its function. Its main function is pumping of blood to the lungs and to all parts of the body. For this pumping, special type of tissues are required which has the property of elasticity. Cardiac muscles tissue has the property of contraction and relaxation. Cardiac muscles tissue is also called myocardium.
