Describe the genetic code and how the nucleotide sequence determines the amino acid and the protein sequence. How can the structure and function of nucleotides (DNA and RNA) allow the cell to assemble specific proteins with different structures and functions?
How much DNA do humans share with bonobos? Do all human cells have the same genome? What is the difference between hybridization and genetic modification? What determines the kind of genes an organism possesses? How do somatic versus germline gamete mutations affect heritability?
In biology and genetics, this external expression (or physical characteristics) is called aphenotype. The phenotype is what is visible, while thegenotypeis the underlying gene combination in our DNA that actually determines what is expressed physically in the phenotype. How Are Traits Determined? Tra...
DNA Basics Almost every cell in your body contains about 2 meters of DNA. If you unraveled all your chromosomes from all the cells of your body, then laid out the DNA end to end, the strands would stretch from the Earth to the Sun about 600 times. - How does all that DNA fit in ...
In this article, we will look deep into the structure of DNA and explain how it makes itself and how it determines all of your traits. First, let's look at how DNA was discovered. DNA is one of a class of molecules called nucleic acids. Nucleic acids were originally discovered in 1868...
Describe the genetic code and how the nucleotide sequence determines the amino acid and the protein sequence. How was the first polymerase transcribed/translated if there was not yet a polymerase in existence? Identify the function of the protein: DNA polymerase III. ...
What is passing on of traits from parents to offspring? The transmission of characteristics from parents to offspring is calledheredity, and the characteristics that are inherited can be predicted. ... DNA technology allows researchers to produce offspring with specific characteristics or abilities. ...
things, including humans. The genome is the complete set of genes present in an organism. It contains all hereditary traits and determines what physical and behavioral features an organism will have. About 20,000 genes make up a genome, which is comprised of DNA sequences that code for ...
Pseudogene: DNA sequences that once encoded protein sequences, but which are no longer transcribed into messenger RNA (mRNA) in a way that translates to functional protein. Stratum: Region on the sex chromosomes where recombination has been suppressed. Strata can be identified by spatial clusters ...
How does RNA structure differ from DNA structure? How has the discovery of DNA structure impacted society? What determines the proteins that DNA will code for? How does DNA control protein synthesis? What are the main structural features of B-DNA?
