Match the technique to the statement. Group of answer choices

1.Protein bound to DNA causes the DNA fragment to run more slowly in the gel than it would if unbound.

2. This technique uses an antibody against a transcription factor crosslinked to chromatin to identify the DNA of interest.

3. A nuclease is used to digest ssDNA from the ends of a labeled DNA probe hybridized to an mRNA to identify the transcription start sight

4.This technique is more exact than a mobility shift assay used for studying DNA-binding proteins like transcription factors.

5. To determine a transcript's start site, an internal primer can be used with reverse transcriptase extending the primer toward the 5' end.

A. Footprinting

B. ChiP

C. S1 nuclease mapping

D. Primer Entension

E. Mobility shift

Both prokaryotic and eukaryotic cells have ribosomes and cell membranes

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
