The nucleus is an organelle and found in eukaryotic cells that store proteins and RNA. It is known as the largest and important cell organelle. The nucleoid is an unevenly shaped region that stores genetic material and is found in prokaryotes.
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.
A Moon mark as brainliest if correct
In sexual life cycle, offspring gets half of it's characteristic from it's father and half from mother, by the process of "Meiosis", so it's resultant characteristic, never matches with any of the parent and variable stablished
Hope this helps!
