Dna stands for in biology6/30/2023 ![]() ![]() Some examples of these kinds of viruses are Canine parvovirus – a contagious parvoviridae virus that affects dogs and Bdellovibrio bacteriovorus – a microviridae that is a host-dependent bacterium. Seawater, marine microbial mats, extreme environments, freshwater, terrestrial environments, metazoan-associated mats and sediments are all places where these viruses that contain single-stranded DNA can be found. These viruses have DNA that does not need or have two strands that will complement each other and so bind together, leaving them as single-stranded DNA genome viruses. This is present as simple - just a strand of nucleotides that is very long. As the ssDNA genome in parvoviridae and microviridae– Some viruses that are members of the family microviridae have genomes that contain single-stranded DNA.These problems can be those such as genetic diseases and cancer. This issue can lead to problems within the organism if they usually have dsDNA present in their nucleus. The accumulation of the ssDNA in the DNA is usually caused by the uncoupling of helicaseunits and replication fork polymerase. ![]() This creates genome instability and is a potential site for mutations and recombination issues in the cell. ( READ: DNA Replication) However, when the cell is in distress, it can cause the single-stranded chromosomes to not bind together, creating many ssDNAs in the cell. These two single strands will then be bound together by single-stranded DNA binding proteins and create more copies of the dsDNA. When the DNA splits, creating the DNA replication fork, it will replicate each side of the dsDNA, creating two single-stranded DNA.
