The molecule connects the sugars in a strand of DNA is phosphate. The molecule connects the sugars in a strand of DNA is phosphate. The section of the DNA double helix that provides structural support to the molecule is known as the phosphate backbone.
The two strands are kept together by base pairs, with adenine and thymine making a base pair and cytosine and guanine creating a base pair. When you look at an image of DNA or RNA, the phosphate backbone is on the outside of the ladder.
In reference to the figure above depicting a DNA replication fork, which of the following is a true statement? the strand labeled "3'" is the leading strand The strand of DNA in the figure above that will be copied first as a series of fragments later joined together by DNA ligase is labeled how
The part of the gene where the DNA polymerase first binds during transcription is called the promoter What is added to the 3' -end of many eukaryotic mRNAs after transcription?
helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting
the lagging strand is labeled with 5'
The three types of RNA involved in gene expression are
