The structure of a strand of DNA. - it is a double helix, like a twisted ladder. the ladder rings are nucleotide subunits and they have a covalent bond to the sugar phosphate backbone (made of deoxyribose and a phosphate group) What are the nucleotide subunits? - adenine, guanine, cytosine, and thymine How are the subunits held together? - through a hydrogen bond What are the nucleotide subunits compliments? - Adenine and thymine cytosine and guanine How does DNA replicate? - the parent s...

DNA is composed of ____ subunits. - ANS Nucleotide DNA has a ____ backbone covalently bonded to _____-containing bases - ANS Sugar-phosphate Nitrogen A DNA molecule contains how many strands of DNA? These strands form what? This means that they are _____. - ANS 2 A double helix Complementary What are the nitrogen-containing bases? - ANS Adenine Guanine Thymine Cytosine The nitrogen-containing bases of the two strands are held to each ot...

Describe the process of transcription. What are the starting molecules and the end products? - ️️Transcription is the manufacture of a strand of RNA complementary to a strand of DNA. In initiation, RNA polymerase binds to a promoter region on the DNA strand. RNA synthesis occurs during the elongation phase as RNA nucleotides are added to the growing RNA polynucleotide. When the RNA polymerase reaches the terminator region of the gene, elongation stops and the polymerase and new RNA molecule ...
