- BFalso
12Protein synthesis is the making of proteins.
- AVerdadero
- BFalso
13Proteins are made up of 20 different kinds of [blank_start]amino acids[blank_end] linked together by [blank_start]peptide bonds[blank_end] to form [blank_start]polypeptide chains[blank_end].
- Aamino acids

- AVerdadero
- BFalso
15Translation happens in the cytoplasm.
- AVerdadero
- BFalso
16During transcription, a [blank_start]protein-coding DNA sequence[blank_end] is transcribed or copied into an [blank_start]RNA molecule.[blank_end]
- Aprotein-coding DNA
- BRNA molecule.
17Transcription happens in the -

- Asomatic
19Meiosis occurs in the [blank_start]sex[blank_end] cells.
- Asex
20Mitosis leads to the production of two daughter cells, each with the same number of chromosomes as the parent cell.
