Gene Expression

All cells carry the entire genome of an organism apart from:

• hair follicles and gametes.

• skin cells and gametes.

• gametes and red blood cells.

• gametes.

Gene expression is the ability for a gene to be:

• in the genome.

• transcribed.

• non-coding.

• a dominant allele.

RNA substitutes uracil for which nucleotide?

• Adenine

• Cytosine

• Guanine

• Thymine

Translation is a process where:

• a polypeptide sequence is produced from a sequence of rRNA codons.

• a polypeptide sequence is produced from a sequence of tRNA codons.

• a polypeptide sequence is produced from a sequence of mRNA codons.

• a DNA nucleotide sequence is used to produce mRNA codon sequence.

Epigenetics modulates genetic expression:

• differently in each cell in the body.

• by altering the genome.

• in response to only intracellular processes.

• consistently throughout an individual's life.

Transcription factors are produced by:

• coding DNA.

• structural genes.

• non-coding DNA and structural genes.

• non-coding DNA.

Hox genes are the most powerful control on the morphology of animals. They do this by:

• being highly conserved.

• coding for the body plan.

• coding body segmentation.

• regulating transcription of other genes.

Monozygotic twins can look different to one another because:

• they have different genetic material from the mother but the same genetic material from the father.

• they have different genetic material from the father but the same genetic material from the mother.

• the environment is determinative of phenotype.

• a mutation has occurred in one twin during embryonic development.
