Answer:
To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:
b b
B Bb Bb
b bb bb
The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.
there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.
Answer:
Please the explanation below
Explanation:
DNA synthesis occur at the S phase of the cell cycle in preparation for cell division. The process which is also known as DNA replication occur in 3 main stages namely:
- Initiation
- Elongation
- Termination
At the initiation stage, the double helix DNA structure is unwound by DNA helicase enzyme to form a Y shape structure known as the replication fork. A short pieces of RNA called primer then binds to 3' end of the DNA strands at the starting point of replication.
During elongation, an enzyme known as DNA polymerase adds bases to the primer in the 5' to 3' direction. This makes the replication of the leading strand to be continuous. RNA primer binds to the lagging strand at multiple regions and are replicated in short disjointed fragments known as okazaki fragments. This kind of replication is discontinuous.
Termination involves the unbinding of RNA primer by an exonuclease enzyme. The primers are then replaced by relevant bases. Proofreading of the newly synthesized strands takes place and the okazaki fragments are joined together by an enzyme known as DNA ligase. Telomerase enzyme then adds telomeres to the end of the DNA strands and each newly synthesized strand winds to its parent strand.
The mushroom will get 0.05 kcals of energy units in the end. This is because at each level, you only pass on 10% of the energy, which then results in the mushroom getting only 0.05 kcals by the end.
