Answer:
mRNA
Explanation:
mRNA, the messenger RNA is the type of RNA that serves as a template for synthesis of proteins. mRNA is formed by the process of transcription that occurs inside the nucleus. The mature mRNA leaves the nucleus and enter cytoplasm to join ribosome.
The sequence of the nucleotide of mRNA is read in the form of genetic code and each triplet codon signifies specific amino acid to be added to the newly synthesized protein. For the purpose, the tRNAs deliver the specific amino acids to the mRNA-ribosome complex while rRNA are the structural components of ribosomes.
I think the statement above is true. <span>Metamorphic rocks can be made up of newly-crystallized minerals formed during metamorphism but they can also include pre-existing minerals unchanged since their crystallization in an igneous rock.</span>
Answer:
D. The nerves exit the central nervous system in the head and from the lumbar spine.
Explanation:
The preganglionic neurons transmit the nerve impulses through the cranial or spinal nerves that arise from the brain, to the postganglionic neurons from where the nerve fibers that relay these nerve signals to the different viscera and effector organs, located along the spinal cord
Answer:
Explanation:
Three-parent baby, human offspring produced from the genetic material of one man and two women through the use of assisted reproductive technologies, specifically mitochondrial manipulation (or replacement) technologies and three-person in vitro fertilization (IVF). In general, the reproductive technologies used to produce three-parent babies focus on replacing or otherwise reducing the effects of mutations that occur in the DNA of cellular organelles known as mitochondria, which reside in the cell cytoplasm. The various approaches could help women to overcome infertility and could prevent the transmission to their offspring of potentially debilitating mitochondrial diseases.
