WebRNA is needed to help carry out the instructions in DNA. Like DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: RNA uses the sugar ribose instead of deoxyribose. WebThe helicase unzips the double-stranded DNA for replication, making a forked structure. The primase generates short strands of RNA that bind to the single-stranded DNA to initiate DNA synthesis by ...

Organisms use lipids for long-term energy storage, in cell membranes, and as molecular signals. The structure of lipids, shown in Figure 1, illustrates that one side attracts water and the other side repels water. WebThe first step in gene expression is transcription, the process of copying information from DNA sequences into RNA sequences. This process is also known as DNA-dependent RNA synthesis. When a sequence of DNA is transcribed, only one of the two DNA strands is copied into RNA, when this RNA encodes a protein is it known as messenger RNA (mRNA). proxy 84 form
