WebThe chromosomes of many organisms are composed of two DNA strands: one strand is oriented in the 5′–3′ direction with respect to the carbon atoms on the sugar (deoxyribose) and the complimentary strand is in the opposite 3′–5′ direction. WebThe human genome, the set of DNA in people, has many more strands of DNA. Most of humans’ DNA is typically packaged into 46 chromosomes located in the cell’s nucleus, which is a specialized compartment for storing DNA. Each of the chromosomes in the nucleus is made up of two linear DNA strands wrapped around each other.

WebRNA polymerase. The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand. Web16 jul. 2024 · 46 DNA molecules. The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types.
