MRNA: AUG AAU UUA GCG ACA
polypeptides: Met or start, Aan, Leu, Ala, Thr
1. The type of mutation that occurred in this strand of DNA is deletion. This may have happened because a small part of the DNA sequence was lost when broken ends were rejoined when the DNA was being repaired.
2. It is not likely that these mutated genes could produce a working protein because the polypeptides were completely changed, which would cause the protein to not work properly.
3. When a seed first absorbs water, it begins to grow. The mutation could cause the plant to be unable to absorb water. Therefore, the plant would be unable to germinate.
Answer:
Explanation:
Bacteria capsule contain poly-γ-d-glutamic acid and also possesses antiphagocytic properties .
Gram positive cell wall peptidoglycan.
Fimbriae contain adhesin which make them to attach to a base and counter shear force and obtain food.
Pili contain oligomeric proteins which is hair like structure.
Endospores consists of DNA, ribosomes and dipicolinic acid.
RIBOSOMES consist of ribosomal RNA and proteins.
Plasmid consist of circular DNA.
Plasma membranes consist lipid bilayer.
The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present.
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
Answer:
Following are the two advantages of endoplasmic reticulum.
1) Endoplasmic reticulum is an organelle of the cell which is responsible for the production of protein for the cell. This protein is sent to the Golgi apparatus where it is modified and used by the cell where it is needed.
2) Endoplasmic reticulum also helps in the removal of toxic substances from the cell. If these toxic substances are not removed, it causes damage to the cell.
Answer:
According to scientists , water occupies up to 60 % of the human body .
The importance of water in the human body are ;
- Transport
- Formation of bodily fluids i.e. saliva
- Digestion
- Regulates body temperatures
- Circulation of nutrients
Explanation:
The reason why it is important to maintain good fluid balance within and without he cells is because , It can dissolve various elements to make then easily absorbed into other system .There are many fluids which rely on water for volume e.g. blood which is the main component of the circulatory systems , water also regulates the temperature and heart pressure ,
Through electrolysis , fluid balance in the cells can be achieved and it also helps to generate nerve impulses .
