Is RNA a single strand?
Yes, RNA is typically a single-stranded molecule. It can form secondary structures due to intramolecular base pairing, but it does not typically have the double helix structure seen in DNA.
A synaptonemal complex would be found during?
A synaptonemal complex is typically seen during meiosis, specifically in prophase I. It helps to facilitate the pairing of homologous chromosomes and the exchange of genetic material between them through crossing over.
What base is always opposite guanine?
In a regular watson-crick double helix base pairing DNA, guanine always pairs opposite cytosine. However this rule holds good only for double helical DNA, as, it is seen in tRNA that guanine (in the anticodon) pairs with cytosine as well as uracil of the corresponding codon in mRNA.
Define complementary base pair?
Complementary base pairs are specific nucleotide pairs in DNA or RNA that bind together due to their specific hydrogen bonding properties. In DNA, adenine pairs with thymine, and cytosine pairs with guanine. In RNA, adenine pairs with uracil instead of thymine.
Which structural characteristic is seen in RNA but not in DNA?
RNA has a ribose sugar and uracil base, whereas DNA has a deoxyribose sugar and thymine base. RNA is typically single-stranded, while DNA is usually double-stranded in living organisms.
