Answer:
c. ribosomes
Explanation:
Like DNA, RNA (ribonucleic acid) is a nucleic acid. This molecule is essential in the synthesis of proteins, since it functions as an intermediary capable of expressing the information present in the DNA. The RNA molecule is formed from the DNA molecule in a process called transcription.
There are three types of RNA, which are tRNA, rRNA and mRNA.
Ribosomal RNA (rRNA) is one of the structural components of the ribosome. It is the rRNA that coordinates the interaction between mRNA, tRNA and proteins, during the process of protein synthesis.
Arteries
The arteries are the blood vessels that carry repeated loads of oxygen-rich blood from the heart to all parts of the body. Arteries are muscular and elastic tubes that operate under high pressure exerted by the pumping action of the heart. The largest artery is the aorta while the arteries' smaller branches are called arterioles and capillaries.
the correct answer is genes
All cells come from preexisting cells. A cell divides its DNA in a process known as mitosis and its cytoplasmic contents in a process known as cytokinesis, producing two new daughter cells while all life begins as a single cell, the human body is not just one cell type. Cells that can divide without becoming a specific cell type (i.e. skin cells) are known as stem cells. When stem cells undergo mitosis and divide, they produce two cells. One cell remains a stem cell and the other is a partially specialized cell known as a progenitor cell. Cells undergo a process of specialization or determination called differentiation to become neurons, muscle cells, or skin cells. Stem cells are the source of all different cell types.
