True. Hope this helps you out!
Answer:
Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.
I’m sorry but I do not understand the question. Furthermore, if you explain I will gladly help my guy :)
Answer:
Tay Sachs
Explanation:
Tay Sachs is a neurodegenerative disorder caused by the deficiency of enzyme hexosaminidase A in lysosome. Lysosome is responsible for degradation of lipid molecules which it carries out by the help of hexosaminidase A enzyme. In absence of the functional enzyme, lipids build up in lysosome which ultimately damages the cell and the tissue. Nerve cells are damaged the most in this disorder.
It is an autosomal recessive disorder which means that the mutant allele must be present in two copies for the production of symptoms. Symptoms are hypotonia, psychomotor regression etc. Its frequency is much higher in Jewish people of Ashkenazi descent. 1 in 30 Ashkenazi Jewish people has the mutant version of the gene.
The lack of centrioles in nerve cells prevents them from undergoing mitosis and meiosis, which prevents them from dividing. Nerve cells do not divide throughout their lives and do not lengthen without doing so.

What is nerve cells?</h3>
The central nervous system is constantly receiving information about the external and internal environment (in the form of sequences of action potentials) from nerve cells, also known as neurons.
Nerve cells are “excitable” cells that may convert a range of stimuli into electrical impulses (CNS). Despite the complexity of the nervous system, neurons and glial cells are the only two types of nerve cells that make up nervous tissue.
The structural and operational components of the nervous system are called neurons. Nerve impulses are electrical signals that are transmitted by them. Neuronal support is provided by glial cells.
Therefore, nerve cells do not reproduce and, if damaged by injury or disease, are lost forever.
