Ans. 25.
Messenger RNA or mRNA has genetic information in the form of triplet codes, called as codons. These codons are made up of three nucleotide bases and each codon codes for a specific amino acid during protein synthesis.
According to codon chart, GCU codes for alanine (Ala), AAU codes for asparagine (Asn), and GUC codes for valine (Val). Thus, the amino acid sequence for the mRNA strand GCU - AAU - GUC is Ala-Asn-Val.
Ans. 26.
a). There are a total of sixty-four codons, made up of combinations of four nucleotide bases (4 X 4 X 4= 64). Out of sixty four codons, sixty one codons code for twenty amino acids that make proteins, while three codons (UAG, UGA, UAA) do not code for any amino acid and act as stop codons. Thus, no protein will be form with the mRNA strand UAG-UGA-UAA.
b). The UAG, UGA, and UAA are stop codons that act as signals to terminate the translation during protein synthesis. Thus, if a ribosome reads the mRNA sequence UAG, UGA, and UAA during translation, it will lead to termination of protein synthesis.
Answer:
A hybrid vehicle has components from both gas-powered and electric car. it has a gas engine and an electric motor. the exact way the two different engines drive the vehicle vary with different models. Other components of gas-powered car present include transmission and steering. But the braking system is usually similar to an electric car which is regenerative to recover the mechanical energy. The energy is stored in batteries just like an electric car.
Secondary succession
Explanation:
The type of succession in this forest is a secondary succession.
A secondary succession is from of succession that occurs in a place that lost it already established ecosystem.
It is succession in an area with soil already formed.
Primary succession is succession in a completely destroyed area that has lost its ecosystem components.
- This kind of succession occurs in an area that a wildfire ravages.
- The first set of plant to populate the area are usually short lived grasses.
- Then shrubs and more vegetation grows.
- With time, perennial forest trees surfaces and the forest is restored.
- Secondary succession is faster
