Assembling Complete Genomic Sequences Based on the Overlap of Sequenced

question 185

Multiple Choice

Assembling complete genomic sequences based on the overlap of sequenced fragments can be difficult because the sequenced fragments:

• A)may be relatively short (50-100 nucleotides).
• B)may have errors in them.
• C)may come from either DNA strand.
• D)may overlap but come from different locations in the genome.
• E)may actually come from bacteria, viruses, or other contaminants.

Definitions:

Vesicular Transport

The movement of molecules across cellular membranes within membrane-bound sacs called vesicles.

Mediated Transport

The movement of substances across cell membranes facilitated by specific transport proteins.

Active Transport

A cellular process that requires energy to move substances across a cell membrane against a concentration gradient.

mRNA

Messenger RNA (mRNA) is a type of RNA that carries genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.
