Question

Centromere
Spindle
RNA
Centriole
Sister chromatids
Frameshift mutation

Answer 1

Unfortunately, as an AI text-based model, I am unable to view or analyze images. Thus, I cannot label the components mentioned in the image. However, I can provide descriptions for each term:

- Centromere: A specialized region on a chromosome where sister chromatids are attached.
- Spindle: A structure formed during cell division (mitosis or meiosis) that helps separate chromosomes and move them to opposite poles of the cell.
- RNA: Ribonucleic acid, a molecule essential for various cellular processes, including protein synthesis.
- Centriole: A small cylindrical organelle found near the nucleus, involved in cell division and formation of the spindle.
- Sister chromatids: Two identical copies of a chromosome, held together by the centromere, created during DNA replication.
- Frameshift mutation: A type of genetic mutation that involves the insertion or deletion of nucleotides in a DNA sequence, causing a shift in the reading frame during protein synthesis.
