Are Tyr TRP2 and TRP1 on the same chromosome?

Are Tyr TRP2 and TRP1 on the same chromosome?

-The TYR, TRP2, and TRP1 genes are identical genes since they are activated by the same transcription factor. -The TYR, TRP2, and TRP1 genes may be located on different chromosomes but with identical operator sequences.

Which of the following claims best explains why keratinocytes do not produce melanin?

Which of the following claims best explains why keratinocytes do not produce melanin? Keratinocytes do not express the MITFMITF gene. In keratinocytes, MITFMITF is not expressed, so it cannot activate transcription of genes involved in melanin production.

Which of the following best predicts the most direct effect of exposing prokaryotic cells to streptomycin quizlet?

Which of the following best predicts the most direct effect of exposing prokaryotic cells to streptomycin? Synthesis of polypeptides will be inhibited. One way scientists hope to use the recent knowledge gained about noncoding RNAs lies with the possibilities for their use in medicine.

Which of the following best explains how bacteria can be genetically engineered to produce a desired antigen quizlet?

Certain strains of bacteria can be used to produce antigens used in vaccines. Which of the following best explains how bacteria can be genetically engineered to produce a desired antigen? The gene coding for the antigen can be inserted into plasmids that can be used to transform the bacteria.

Which of the following best explains how the base pairs form?

Which of the following best explains how the base pairs form? Hydrogen bonds join a double-ringed structure to a single-ringed structure in each pair.

How do nucleotides pair with one another in a DNA molecule?

The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
