Molecular Biology-Genome Structure & Genomic Variations

Question 1

Intergenic regions

Answer 1

composed of noncoding DNA, stretches between genes

Question 2

what are genomic regions with high transcription rates rich in?

Answer 2

genes

Question 3

gene

Answer 3

DNA sequence that encodes a gene product; includes both regulatory regions and a region that codes for either a protein or a non-coding RNA

Question 4

single nucleotide polymorphisms (SNPs)

Answer 4

mutations at a single nucleotide, most common type

Question 5

copy-number variations (CNVs)

Answer 5

structural variations in the genome that lead to different copies of DNA sections

Question 6

tandem repeats

Answer 6

short sequences of nucleotides repeated one right after the other

Question 7

between individuals, how do tandem repeats vary?

Answer 7

variations in length/number of repeats
