Answer:
D
Explanation:
i think this is the answer because the nucleus contains threads of DNA called chromosomes.which can help in a genetic experiment.
I hope this helps
In the given context, Nucleus would help in obtaining the copies of the gene.
The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information.
What is Nucleus?
In cell biology, the nucleus is a membrane-bound organelle found in eukaryotic cells.
The nucleus was discovered by Robert Brown in 1831.
Nuclear DNA is a multiple long linear molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function.
The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression and thus control the center of the cell.
The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle.
Nucleus houses an organism’s genetic code, which determines the amino acid sequence of proteins critical for day-to-day function, it primarily serves as the information center of the cell has been found that replication happens in a localized way in the cell nucleus.
What is Ribosomes?
A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.
Ribosomes are specialized cell organelles and are found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins.
This cell organelle also functions by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA.
They transfer RNAs (tRNAs) comprising amino acids and enter into the ribosome at the acceptor site. Once it gets bound up, it adds amino acid to the growing protein chain on tRNA.
What is Mesosome?
Mesosome is formed by an extension of the plasma membrane into the cell wall. These extensions are usually in the form of vesicles, tubules, and lamellae.
The main use of mesosomes are:
- Synthesis of a cell wall.
- DNA replication.
- Distribution of daughter cells, respiration, secretions, etc.
What is Plastid?
Plastids are double-membrane organelles which are found in the cells of plants and algae.
Plastids are responsible for manufacturing and storing of food. These often contain pigments used in photosynthesis and different types of pigments that can change the color of the cell.
Different types of plastids with their specialized functions are:
- Chloroplasts
- Chromoplasts
- Gerontoplasts
- Leucoplasts
