How does synthesis of the leading strand differ from synthesis of the lagging strand during dna replication?
Alexandra [31]

Answer:

DNA replication is a process where the DNA is copied and replicates to produce the 2 identical copies of the molecule. Strands of DNA molecule work as a template for the production of complementary strands. The DNA splits synthesizing a fork. A new DNA is always synthesized in a 5' prime to 3' prime manner. Replication of both the DNA strands goes in two different ways.

1) Leading strands: It is a strand which is goes to the direction same as the replication fork movement and synthesized in 5'-3' prime direction. This strand formation is occurred as nucleotides are continuously added to the 3' prime end after polymerase reads the DNA template (original).

2) Lagging strands: It is a strand which is goes to the opposite direction as the replication fork movement and synthesized in 3'-5' prime direction. It is synthesized in fragments which are known as okazaki fragments. Lagging strand synthesis needs RNA primase.

Inheritance patterns cannot always be explained by Mendels models of inheritance. If a pair of homologous chromosomes fails to s
valentinak56 [21]

Answer:

n+1; n+1; n-1; n-1

Explanation:

Separation of homologous chromosomes during anaphase I result in a reduction of the chromosome number to half in the daughter cells of meiosis. If two homologous chromosomes of a pair fail to separate from each other, they both will move to the same pole. In this case, one daughter cell of meiosis I will have both the homologous chromosomes of a pair (n+1) while the other one will lack it (n-1). Meiosis II in these two daughter cells will form a total of four cells. Two of the daughter cells will have one extra chromosome (n+1) while the rest two will lack one chromosome from the haploid set (n-1).

1. How could you test to see if an enzyme was completely depleted during an experiment?
pishuonlain [190]
To test, increase the amount of substrate. If the amount of reaction changes then the enzyme has not depleted. If the amount of reaction does not change then the enzyme has completely depleted.

In living organisms, energy from the oxidation of organic molecules provides most of the energy needed to create favorable condi
Alexandra [31]

Answer:

True

Explanation:

All the cells in a living organism undergo cellular respiration to extract the chemical energy from food molecules and convert it into  usable energy form of ATP.

The food molecules having chemical energy are oxidized to produce energy that can be used for all  cellular metabolism processes and other energetic reactions required for life

Later on this ATP's energy is used for building new molecules and transporting materials.

Hence, given statement is true
