Answer:
- There are three main steps to DNA replication: initiation, elongation, and termination.
- In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
Answer:
lateral; inferior
Explanation:
In anatomical terms:
- Superior is towards the head, and <u>inferior </u>is towards the feet.
- Medial is towards the centre of the body (belly button) whereas <u>lateral </u>is towards the outside of the body (towards the hip bones and arms, for example)
- Posterior is towards the back (spine), whereas anterior is towards the front (belly)
Therefore, the fingers are lateral (to the side) and inferior (lower) than the heart
Answer:
Mutations during meiosis can often lead to disorders, diseases, etc.
Explanation:Let's say that one of the tetrads formed in the first steps of meiosis It doesn't separate and goes on.
When making gametes, some will contain the necessary amount of chromosomes while others will not
Answer:
Electron transport chain
Explanation:
Cellular respiration is the process whereby glucose is broken down in the cell to yield energy in form of ATP. This process, which is important to the metabolic functioning of every organism, occurs in three major stages namely: glycolysis, kreb's cycle and electron transport chain (ETC).
According to this question, a stage of respiration is described as follows:
- Two pyruvate molecules undergo a chemical reaction, combining with coenzyme A to form two acetyl-CoA molecules.
- Two carbon dioxide molecules and two NADH molecules are formed as a result of this process.
The process depicted above is KREB'S CYCLE of cellular respiration, hence, the stage of respiration that immediately follows the process is called ELECTRON TRANSPORT CHAIN (ETC).
Answer:
GG, Gg, Gg, gg
Homozygous green – GG
Heterozygous green – Gg
Homozygous yellow - gg
Explanation:
It is given that allele for green seed pods (G) is dominant to the allele for yellow seed pods (g) which means that if “G” and “g” occur together, a trait associated with G will be expressed.
The genotype of the true breeding Green plant is “GG”
The genotype of the true-breeding yellow plant is “gg”
F1 generation cross
GG * gg
Offspring produced from F1 generation are – Gg, Gg, Gg, Gg
In f2 generation offspring of F1 generation are crossed among each other.
So the offspring produced in F2 generation are
Gg * Gg
GG, Gg, Gg, gg
Homozygous green – GG
Heterozygous green – Gg
Homozygous yellow - gg
