Adenine pairs with Thymine (A=T) AND Cytosine pairs with Guanine (C=G)
Ans.1. False.
RNA or ribonucleic molecules are polymer of nucleotide molecules that perform various functions in a cell. rRNA is referred as ribosomal RNA and are involved in synthesis of ribosomes along with proteins. Ribosomes are described as molecular factory for protein synthesis, hence, rRNA plays an important role in protein synthesis.
Thus, given statement is false.
Ans.2.
Transcription is defined as a process, by which a parental DNA molecule gets transcribed into a RNA molecule with the help of RNA polymerase enzyme. The RNA molecule is then, translated into a specific polypeptide chain or protein.
According to central dogma of molecular biology, genetic information flows from a DNA molecule to a protein. During this, first step includes transcription (formation of RNA from DNA) and second step includes translation (formation of protein form RNA).
Thus, transcription plays an important role in the central dogma of molecular biology.
In cell division, the cell that is dividing is called the parent cell. the parent cell divides into two daughter cells. the process than repeats in what is called the cell cycle. cells regulkate their division by communicating with each other hope it helps,if you need help just ask and i will be more than happy to help. :)
Answer:
ATP synthase utilizes energy of the proton gradient to attach phosphate groups to ADP.
Explanation:
ATP synthase is an enzyme that requires some form of energy to form energy storing molecule ATP, from adenosine diphosphate (ADP) and inorganic phosphate (Pi). Because of that, ATP synthesis is coupled with cellular respiration and electrochemical gradient created by the difference in proton (H+) concentration across the mitochondrial membrane during the transport of electrons through the electron transport chain. In plants, proton gradient is formed in chloroplast, in the thylakoid lumen through the thylakoid membrane.
Starfish move slow because of the material that is on the body. Also because they have a water vascular system. Water goes into the canal and they move based on that system.
Why don't you got to the beach and look at that part;)
Hope this answer helped!<span />
