a structure composed of DNA wrapped around eight histones
Which of the following best describes the central dogma of gene expression?
During transcription, DNA codes for messenger RNA (mRNA), which codes for polypeptides during translation.
Transcription begins on a site on DNA called ( ) and ends at a site on DNA known as ( ).
a promoter, the terminator
Similar to DNA replication, transcription can be divided into the following stages
Initiation, elongation, termination
During eukaryotic RNA processing, the non-translated sequences that are removed are called
The bacterial RNA polymerase requires which of the following for promoter recognition?
Introns are occasionally found in transfer RNAs and ribosomal RNAs. These introns are not removed by a spliceosome. The introns rather undergo self-splicing. Such RNAs that can catalyze chemical reactions are known as?
The genetic code is said to be degenerate because
multiple codons can specify the same amino acid
During maturation of a pre‐mRNA in the eukaryotic nucleus, the 5’end and the
3’end of the RNA are modified through
. a 7‐methylguanosine cap and a poly A tail, respectively.
