Question

ATP
DNA polymerase
tRNA
ribosome
helicase
UTP
RNA polymerase
AUG start site
Okazaki fragment
promoter
2.) Introns are... (Choose all that apply)
removed from DNA by splicing
usually found in human genes
usually found in bacterial genes
the coding regions of genes
transcribed as part of an RNA molecule
3.) A mutant protein can be created by... (Choose all that apply)
a change of a base in the middle of an intron.
insertion of a base between +1 and the start codon.
a change in a splice site.
a change of the third base of a threonine (THR) codon.
insertion of a base within an open reading frame.
Explanation / Answer
1. ATP - required for Transcription, translation DNA polymerase - required for DNA replication. tRNA - required in Translation. tRNA - required in Translation. Ribosome - required in Translation. Helicase - required in DNA replication, transcription. UTP - required for transcription. RNA polymerase - required in transcription. AUG start site - required in tranlation or protein synthesis. Okazaki fragments - seen in DNA replication. Promoter - required in transcription. 2. Introns are usually found in bacterial genes and transcribed as a part of RNA molecule. When proteins are generated fom intron-containing genes, RNA splicing takes place as a part of the RNA processing that follows transcription and precedes translation. 3. A mutant protein can be created by insertion of a base between +1 and the start codon. 2. Introns are usually found in bacterial genes and transcribed as a part of RNA molecule.
