The correct answer is: DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication
DNA polymerase is an enzyme that synthesizes DNA during the DNA replication by adds nucleotides to the 3’ end of a primer. This means that the new chain is formed in a 5’ → 3’ direction.
Because double-stranded DNA is antiparallel, DNA polymerase moves in opposite directions on the two strands-leading and lagging strand.
The leading strand is copied continuously since DNA polymerase is moving towards the replication fork. The lagging strand is copied discontinuous. DNA polymerase is moving away from the replication fork (and helicase that separates the strands), so it must constantly return to copy newly separated stretches of DNA. So, the lagging strand is copied as a series of short fragments-Okazaki fragments that are joined together by a combination of DNA pol I and DNA ligase.
Answer:
330
Explanation:
A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.
Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.
993-stop codon =990
990/3=330
So that's why 330 amino acid will be incorporated in the polypeptide chain.
Question: "Water is a product of the reduction phase of the Calvin Cycle. How many water molecules are produced?"
Answer: "Six water molecules are formed during the reduction phase of the Calvin Cycle, creating water."
Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."
Explanation:
Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.
Answer:
c) intracellular fluid
Explanation:
Body fluids are dilute and watery solutions and contain the dissolved chemicals that are found inside cells as well as surrounding them. The body fluid which is present within cells is called intracellular fluid (ICF). The fluid present outside body cells is extracellular fluid (ECF). The extracellular and intracellular body fluids of individual cells are separated from each other by the plasma membrane.
The intracellular fluid makes cytosol which is a fluid component of the cytoplasm in which the organelles are suspended. In lean adults, body fluids make between 55% and 60% of total body mass in females and males, respectively.
Around 45% and 40% of the total body mass of males and females is solid. Out of the total body fluid, 2/3 is constituted by intracellular fluid while rest 1/3 of the body fluid is extracellular fluids. The interstitial fluid makes 80% of the total extracellular fluid while the rest 20% is blood plasma.
