I'm pretty sure the blank is underneath. Hope this helped. Have a great day! :D
Answer:
Because DNA polymerase can synthesize DNA strands in 5' to 3' direction only.
Explanation:
The 5' end of one DNA strand is present opposite to the 3' end of the other strand. But DNA polymerase enzyme can elongate the primers in 5' to 3' direction only. Formation of a phosphodiester bond between the existing nucleotide and the incoming nucleotide requires the free 3'OH. This 3' OH serves in the nucleophilic attack during the formation of the bond.
Therefore, the lagging strand is synthesized discontinuously in the form of short DNA fragments. These are called Okazaki fragments. Primers are formed for short distances which in turn are elongated by DNA polymerase to form the Okazaki fragments. On the other hand, the synthesis of the leading strand occurs continuously in the same direction in which the replication fork moves.
Answer:
Explanation:
As you probably already know, all of the cells in your body started from a single cell. That single cell then divided many, many times to turn into the 50 trillion or so cells that make up you. Almost all of the cells in your body share the same DNA as was found in that first cell
The components that make up the genetic code are common to all organisms! Same NUCLEOTIDES, same BACKBONE same BASE-PAIRS, same HYDROGEN BONDS! The instructions for making proteins (and traits) are in the sequence of nucleotides! These are the GENES that hold our similarities or differences
Answer:
The correct answer is - 1. true, 2. true, 3. false, and 4. true.
Explanation:
1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.
2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.
3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.
4. when the light reaction takes place retinal converted to opsin
The answer is A, Genetic diversity in the new insect population will be lower due to the founder effect
