Letter
Definition/Description
A multipart enzyme consisting of a core enzyme along with other proteins required for full function. For example, sigma factor bound to RNA polymerase.
A multipart complex that removes introns from pre-mRNA and joins together exons.
A region of bacterial DNA that contains genes that are physically grouped together because they are needed for a related function. The genes are transcribed together into one mRNA.
A gene that is always expressed or codes for a protein that is always present in a cell.
The entire set of processes that convert a gene into a functional product, most commonly an active protein.
Genes and operons that have the same regulatory sequences and are controlled by the same regulatory protein; allows global gene expression in bacterial cells.
A positively charged protein that is abundant in eukaryotic chromatin.
A bead-like unit of eukaryotic chromatin, consisting of DNA wrapped around eight histone proteins.
The collective term for any mechanism of inheritance that is due to something other than differences in DNA sequences.
A small, single stranded RNA molecule that can join with a RISC to target mRNA for destruction or block translation.
Viral enzyme that that can synthesize RNA from an RNA template; also known as RNA-dependent RNA polymerase
An enzyme that can synthesize DNA from an RNA template; enzyme found in retroviruses

Explanation / Answer
A multipart enzyme consisting of a core enzyme along with other proteins required for full function. For example, sigma factor bound to RNA polymerase. is holoenzyme.
A multipart complex that removes introns from pre-mRNA and joins together exons is spliceosome.
A region of bacterial DNA that contains genes that are physically grouped together because they are needed for a related function. The genes are transcribed together into one mRNA is operon.
A gene that is always expressed or codes for a protein that is always present in a cell is constitutive gene.
The entire set of processes that convert a gene into a functional product, most commonly an active protein is gene expression.
Genes and operons that have the same regulatory sequences and are controlled by the same regulatory protein; allows global gene expression in bacterial cells is regulon.
A positively charged protein that is abundant in eukaryotic chromatin is histones.
A bead-like unit of eukaryotic chromatin, consisting of DNA wrapped around eight histone proteins is nucleosome.
The collective term for any mechanism of inheritance that is due to something other than differences in DNA sequences is epigenetic inheritance.
A small, single stranded RNA molecule that can join with a RISC to target mRNA for destruction or block translation is microRNA.
Viral enzyme that that can synthesize RNA from an RNA template; also known as RNA-dependent RNA polymerase is RNA replicase
An enzyme that can synthesize DNA from an RNA template; enzyme found in retroviruses is reverse transcriptase
