A gene is: a segment of DNA that codes for a protein a set of homologous chromosomes a molecule within DNA a type of pants. 8. The twisted ladder shape of DNA is called a: hydrogen twist deoxyribose flip double helix double membrane. 9. Each strand is made up of a long chain of nucleotides, and the two strands are held together by hydrogen bonds between complementary nucleotides. This double helical structure is a key feature of DNA and allows for its replication and transmission of genetic information. Therefore, the correct answer is False. 5.Created Date: 12/17/2013 12:07:19 PMAnswer: Conservative replication is a hypothetical form of DNA synthesis in which the two template strands remain together but dictate the synthesis of two new DNA strands, which then form a second DNA helix.

Crick made a revelatory ...The picture above shows the replication fork in the DNA replication process. The replication fork is the point where the DNA double helix is unwound and the new strands are being synthesized. It is formed by the separation of the two parental DNA strands, and it moves along the DNA molecule as replication proceeds.

The order of nucleotides in a gene (in DNA) is the key to how information is stored. For example, consider these two words: stable and tables. Both words are built from the same letters (subunits), but the different order of these subunits results in very different meanings. In DNA, the information is stored in units of 3 ...…
