2 mar 2012 · DNA exists in various structural forms and undergoes compaction in the cell, ultimately forming chromatin through association with histone proteins. The primary function of DNA is to serve as the template for its own replication and transcription into RNA to direct protein synthesis.
11 wrz 2019 · DNA is a double-stranded molecule that forms a helical structure. It is composed of nucleotides, each containing a phosphate group, deoxyribose sugar, and a nitrogenous base. There are two types of bases: purines (adenine and guanine) and pyrimidines (cytosine and thymine).
2 kwi 2012 · Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.References: http:...
20 lut 2019 · DNA strcture and function. DNA contains the genetic instructions for living organisms. It exists as a double helix structure with two strands bonded together via hydrogen bonds between complementary nucleotide base pairs. Watson and Crick discovered the double helix structure in 1953, which has a sugar-phosphate backbone and pairs of ...
11 lis 2019 · This PowerPoint resource provides a useful visual aid for a lesson on the discovery and structure of DNA. It includes activities, questions and video links. I usually begin the lesson by inviting students to write down everything they already know about DNA in a black pen.
describe the structure of a nucleotide as a central deoxyribose sugar bonded to a nitrogenous base and a phosphate group, state DNA that is read in the 5’ to 3’ direction, explain how DNA can be extracted from organic material, such as fruit.
