Description

Describe Mendel’s conclusions about how traits are passed from generation to generation.

Traits are controlled by a pair of genes and that is during gamete formation separate from each other. So, each parent give one hereditary factor to the offspring, therefore the offspring receives two hereditary factors to express a trait. Mendel worked on pea plants and found that gene transmission from parents to offspring. He used controlled crosses to explain this process.

How is genetic information encoded in a DNA molecule?

The information is encoded by the four nitrogenous base sequence Adenine, Cytosine, Guanine and Thymine (A,C,G,T) in the DNA. Contrast chromosomes and genes.

Chromosomes are made from DNA molecules and are found in the nucleus. It is the structure that carries the genetic material. A chromosome codes for many proteins A gene is located inside the chromosomes any factor of inheritance is caused from a gene. A gene code for one trait. Each gene contains a code for a specific sequence of amino acids that codes for a specific protein. So, DNA is on the gene and gene is on the chromosome What is the chromosome theory of inheritance, and how is it related to Mendel’s findings?

The theory was proposed based on experiments by Thomas Hunt Morgan using fruit flies it states that inherited traits are controlled by genes on chromosomes transmitted through gametes. Mendel worked on pea plants and found that gene transmission from parents to offspring. Both the chromosome theory of inheritance and Mendel's findings are the same.

Contrast telophase in plant and animal mitosis.

The difference is the way in which cytokinesis occurs. In animal cells the cell membrane is pulled in by a ring of filaments and this continued until the cytoplasm splits in two. However, in the plant cells the cell plate forms midway between the two nuclei of the cells, the cell plate grows outward until a new cell wall has grown between the two cells...
