Question

part d: complete the table below.
protein synthesis practice
location in the cell
building blocks used
purpose
dna replication
nucleotides: two ______
to make
transcription
nucleotides: ____ from ____
to produce a strand
translation
trnas and ____ from ____
to produce

Explanation:

• DNA Replication:
• Location: Nucleus (in eukaryotic cells). DNA replication occurs in the nucleus as the DNA is housed there.
• Building blocks used: Nucleotides. DNA is made up of nucleotides (adenine - thymine, cytosine - guanine pairs).
• Transcription:
• Location: Nucleus. Transcription (synthesis of mRNA from DNA) occurs in the nucleus where the DNA template is present.
• Building blocks used: Nucleotides (specifically ribonucleotides for mRNA). mRNA is synthesized using ribonucleotides complementary to the DNA template.
• Translation:
• Location: Ribosomes (in the cytoplasm). Ribosomes are the sites where translation (synthesis of proteins from mRNA) occurs.
• Building blocks used: Amino acids. tRNAs bring amino acids to the ribosomes according to the mRNA codons.

Answer:

Process	Location in the cell	Building blocks used	Purpose
Transcription	Nucleus	Ribonucleotides (from DNA template)	To produce a strand of mRNA
Translation	Ribosomes (in cytoplasm)	Amino acids (from tRNAs)	To produce a protein
