Question

Indicate true (T) and false (F) statements below regarding the nuclear transport of proteins. Your answer would be a four-letter string composed of letters T and F only, e.g. TTTF.

(A ) Many nuclear import and export receptors are members of the same protein family.
( B) Most nuclear import receptors contain unstructured domains with FG-repeats.
( C) Adaptor proteins that simultaneously bind to nuclear localization signals and to importins are required for the import of some nuclear cargo proteins.
( D) Ran is mostly found in its GTP-bound form in the nucleus.

Answer 1

The true and false statements regarding the nuclear transport of proteins are T, F, T, T, respectively, covering aspects of protein family membership, FG-repeats, adaptor protein requirements, and the form of Ran in the nucleus.

Step-by-step explanation:

Indicating true (T) and false (F) statements regarding the nuclear transport of proteins, the correct sequence is TFTT:

• (A) Many nuclear import and export receptors are members of the same protein family. - True (T)
• (B) Most nuclear import receptors contain unstructured domains with FG-repeats. - False (F)
• (C) Adaptor proteins that simultaneously bind to nuclear localization signals and to importins are required for the import of some nuclear cargo proteins. - True (T)
• (D) Ran is mostly found in its GTP-bound form in the nucleus. - True (T)
