Answer:
During translation, tRNA (transfer RNA) molecules match a sequence of three nucleotides in the mRNA to a specific amino acid, which is added to the growing polypeptide chain. RNA primers are not used in protein synthesis. RNA primers are only needed to initiate a new strand of DNA during DNA replication.
Answer:
C. Steroids
Explanation:
Some lipids such as steroid hormones serve as chemical messengers between cells, tissues, and organs, and others communicate signals between biochemical systems within a single cell.
Explanation:
Hi there!
Cell cycle has 2 phases (i.e M-phase and Inter-phase). Interphase is considered to be the longest phase. Interphase also has G1-phase, S-phase and G2-phase. In cell cycle while moving from M-phase it has two option either to go in G1-phase or G0 phase. It it goes to G0-phase it doesn't go under cell division but if it goes to G1-phase it starts to prepare materials required to replicate or copy DNA. After preparing all the material it goes in S-phase and copies DNA. It doesn't go to G2-phase until it copies DNA perfectly. Then it goes to G2-phase. In this phase it prepares material for replication of other cell organelles.
Therefore, DNA is copied in S-phase.
Hope it helps!
Answer:
Glucose Molecule
Explanation:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose.
