Based on experiments similar to these, gregor mendel devised a theory of inheritance. use your own observations to come up with your own explanation of how a trait such as fur color is passed down from parents to offspring. if possible, discuss your theory with your classmates and teacher.
Fur colour is passed down to the offspring with the help of an independent assortment of genes. Depending on the dominance of the gene, the trait is expressed.
What is Mendel's law of inheritance?
Mendel proposed three laws regarding inheritance, such as the rule of dominance, the law of segregation, and the law of independent assortment. The genes responsible for fur colour have two variants (alleles), one dominant and one recessive.
The allele segregates independently during gamete formation according to the rule of segregation. The alleles pass to offspring by the law of independent assortment. In this way, the colour of the fur is expressed.
Hence, fur colour is passed down to the offspring with the help of these Mendelian laws.

what are the functions of sds in gel electrophoresis for estimating protein sizes? (check all that apply) group of answer choices
I and II is the correct answer
What is gel electrophoresis?Gel electrophoresis is a technique used in laboratories to molecularly separate mixtures of DNA, RNA, or proteins. it is a technique used to sort biological molecules according to size. The molecules to be separated are driven through a gel with tiny holes by an electrical field. By putting these molecules in a gel with tiny holes and applying an electric field across the gel, it is possible to separate the molecules. The negatively charged nature of DNA causes it to move toward the positively charged electrode when an electric current is supplied to the gel. Because shorter DNA strands pass through the gel more quickly than longer strands, the fragments are organized according to size.
The following list of fundamental processes for performing gel electrophoresis includes:
Pouring the gel first, getting your samples ready, the gel must be loaded, run, stained, and exposed to an electric field while doing so.
Using a technique called agarose gel electrophoresis, nucleic acid (DNA or RNA) fragments are separated according to their size
1.linearizes the protein
2.II by causing hydrogen bonds in proteins to be broken. gives proteins a general negative charge, limiting the effect of protein size
3.III on gel migration distance. allows the protein to be seen on the gel by intercalating between its amino acids.

how does dna replication between prokaryotes and eukaryotes compare/contrast? choose all that apply.
SIMILARITIES
All prokaryotic and eukaryotic species replicate their DNA in a similar manner. The DNA helicase enzyme is responsible for unwinding the DNA . Polymerases are an enzyme family that facilitates the synthesis of new DNA strands.
Both kinds of organisms also adhere to a replication strategy known as semi-conservative replication. A leading and a trailing strand are created in this arrangement as a result of the distinct directions in which the individual DNA strands are produced.
Small DNA fragments known as Okazaki fragments are produced and subsequently fused to form lagging strands. Both kinds of organisms start new DNA strands with a little RNA primer.
DIFFERENCES
The discrepancies in the size and complexity of the DNA and cells of these organisms are largely responsible for the differences between prokaryotic and eukaryotic DNA replication. A prokaryotic cell has 25 times as much DNA as an ordinary eukaryotic cell.
Prokaryotic cells have a single point of origin, simultaneous replication in two opposing directions, and cytoplasmic replication.
On the other hand, eukaryotic cells use unidirectional replication within the cell nucleus and have numerous sources of origin. Eukaryotes have four or more different types of polymerases, compared to one or two in prokaryotic cells.
Prokaryotic cells replicate far more quickly than eukaryotic cells do. While animal cells like human cells can take up to 400 hours, some bacteria can grow in as little as 40 minutes. Eukaryotes also have a unique method for duplicating the telomeres that are found at the ends of their chromosomes.
Prokaryotes contain circular chromosomes, which eliminate the need for ends. Finally, whereas eukaryotic cells only undergo DNA replication during the S-phase of the cell cycle, short replication occurs almost continuously in prokaryotes.
