Genetics Final

The DNA backbone is held together by

: phosphodiester bonds

Homologous chromosomes of a heterozygous individual contain

: different alleles of a gene

Nucleotides / nucleic acids / amino acids contain genetic information.

nucleic acids

To identify that a trait shows incomplete dominance it is necessary to observe homozygotes or heterozygotes.

: heterozygotes

is able to proofread newly synthesized DNA to detect errors.

: polymerase (DNA polymerase)

The main difference between nucleotides of DNA and RNA is in the type of present in the molecule.

: side chain (the sugar)

Somatic cells contain (twice as much / the same amount / half as much) genetic information as an organism’s gametes.

twice as much

Transcription factors bind to sequences.

: regulatory

If you compared cells in your skin to cells in your liver, the would show the most differences related to cell function.

: proteome

Proteins which will function in the cytoplasm are translated in the .

: cytoplasm (by free ribosomes)

Epigenetic gene regulation (is / is not) related to the structure of the chromosome at a gene location.

is

inhibits transcription.

DNA Methylation

The spliceosome removes from RNA transcripts.

: introns

Traits that are completely genetically determined have high .

: heritability

Mutations increase variance.

: genetic

The ability to generate fertile hybrids is an indicator that the parents (are / are not) of the same species.

: are not

The gene pool represents all of the of a population.

: alleles

Phenotypic variance (Vp) represents the of a trait in a population.

distribution

occurs when multiple genes affect the same trait.

: epistasis

To determine if a population is changing over time you could compare animals from different .

generations
