When the Nontemplate Strand of a Gene Is Transcribed into RNA

question 21

Multiple Choice

When the nontemplate strand of a gene is transcribed into RNA, what is likely to result?

• A) A complementary sRNA will bind to it and form a functional ribozyme with secondary structure.
• B) It will complementarily bind to the gene sequence, form a hairpin loop, and transcriptionally repress the gene.
• C) The complementary mRNA transcribed from the template strand will bind to it and halt its translation.
• D) A global regulator will identify this as a stress, respond by inducing ribonuclease production, and it will be degraded.

Definitions:

Heredity

The transmission of genetic information from parent to offspring.

Pleiotropy

A genetic phenomenon where a single gene influences multiple phenotypic traits.

Polygenic Inheritance

A mode of inheritance where traits are influenced by multiple genes at different loci, leading to a continuous range of possible phenotypes.

Incomplete Dominance

A genetic scenario in which one allele does not completely dominate another allele, leading to a phenotype that is a blend of the two alleles.
