Describe . the basic process. of . DNA replication . and how it relates . to the . transmission . and . conservation. of . the genetic information. DNA and Its structure. DNA (deoxyribonucleic acid) is a large organic. When DNA codes for RNA, the process is called . TRANSCRIPTION. . When RNA codes for proteins, the process is called . TRANSLATION. .. There are 3 types of . rna. , however only mRNA is involved in transcription. Take a notes sheet from the front table. Get out your warm-up sheet & answer the following:.

Generally, DNA viruses copy their genomes . Transcription, translation and transport. Transcription of virus genome. In the summary of the scheme depicted . below, most . of the nucleic acid strands are . labelled. (+) . or (. −). This . labelling. .. The length of the transcription bubble is about 12 to 14 . bp. , but the length of the RNA–DNA hybrid within the bubble is only 8 to 9 . bp. . As the enzyme moves along the template, the DNA duplex reforms. Viruses are very small – smaller than the smallest cell.. They are usually surrounded by a capsid of proteins.. For replication, viruses rely on their host cells . ie. ., the cells they infect.. Most viruses exhibit a limited host range- they typically infect only specific types of cells of one host species..
