Answer:
The answer is <u>C.) 1953, Watson and Crick</u>. In <u><em>1953</em></u>, with the help of Rosalind Franklin, <u><em>Watson and Crick</em></u> discovered the structure of DNA.
Explanation:
To be specific, James Watson and Francis Crick were the first people to make a 3-D model of DNA. Although it may not seem much today, as our technology has advanced so much ever since, it was big time in 1953. They discovered that DNA was shaped like a double-helix, or twisting ladder. Pretty intriguing if you ask me!
Answer:
The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.
Explanation:
Answer:
Answer:
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. ... Each group of three bases (codon) corresponds to one of 20 different amino acids used to build the protein.
OR
Gene expression is. the activation of a gene leading to the transcription, translation and synthesis of a specific protein.
Answer:
- Past genetic knowledge has mostly been replaced.
- Early researchers were hampered by a lack of knowledge of DNA structure and function.
Explanation:
Genetics is the part of biology that studies heredity, that is, how traits are passed down from generation to generation. Many technologies have been created so that scientific research can find new genetic discoveries and facilitate our understanding on this subject.
The first scientific research that tried to explain genetic phenomena was created long ago, but this research generated an archaic knowledge that can be replaced thanks to technology and scientific advancement in this area. This archaic knowledge is the result of research where researchers were unaware of the existence of the DNA molecule, which is the main vehicle in the transmission of heredity.
Unbeknownst to DNA, these researchers attributed heredity to elements that do not correspond with what actually happens, but we cannot dismiss the importance of such research for the technologies and genetic knowledge we have today.
