Part 3: Nucleus Parts

Question 1

The semi-fluid, gel-like substance within the nucleus, comprising the majority of its volume. It serves as the medium in which the nucleolus, chromatin, and other nuclear components are suspended.

Answer 1

Karyoplasm (Nucleoplasm)

Question 2

Large protein complexes embedded in the nuclear membrane, creating perforated holes that allow the selective exchange of molecules between the nucleus and the cytoplasm.

Answer 2

Nuclear Pores

Question 2

A double-layered membrane that encloses the nucleus, separating its contents from the cytoplasm. The nuclear membrane consists of an inner and outer layer, with the outer layer being continuous with the endoplasmic reticulum.

Answer 2

Nuclear Membrane (Nuclear Envelope)

Question 3

dense structures within the nucleus primarily involved in the synthesis of ribosomal RNA (rRNA) and the assembly of ribosomal subunits.

Answer 3

Nucleoli (Nucleolus)

Question 4

long thread structure that carrying genes

Answer 4

Chromosomes

Question 5

consisting of DNA and histone proteins that packed into thin, stringy fiber

Answer 5

Chromatin

Question 6

genetic code

Answer 6

DNA

Question 7

either of the two strands of a replicated chromosome

Answer 7

Chromatid

Question 8

basic unit of heredity and consists of specific sequence of DNA/RNA

Answer 8

Gene
