Answer:
48 amino acids
Explanation:
The wild type gene codes for a protein with 100 amino acids. One amino acid is encoded by one triplet code of the gene. This means that the wild type gene has a total 100 triplets or 300 nucleotides to code for a protein of 100 amino acid. Mutation in this protein has introduced the code "UAA" at the 49th codon. The code "UAA" is a stop codon. Therefore, the mRNA transcribed from the mutant allele would code for a protein having 48 amino acids as the protein synthesis will be stopped once the stop codon at the 49th position is read.
Answer:
it would be C, since an abiotic factor is a non-living thing that helps shape the ecosystem.
Explanation:
If you look at A it lists flowers, which are alive. If you look at B it lists bacteria, which is alive. C doesn't list anything thats alive. D lists insects, which are alive.
Answer:
Option (1), (2) and (3).
Explanation:
DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.
Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.
Thus, the correct answer is option (1), (2) and (3).
Answer: D) a hollow soccer ball
Explanation:
Carbon is capable of forming many structurally different forms of the same element due to its valency. These forms are called allotropes. One of these is the buckminsterfullerene. It has a cage-like fused-ring structure made of twenty hexagons and twelve pentagons. If you look at this structure, it resembles a soccer ball.
Answer:
Found within wet and dry tropical forests, it grows in a variety of soil types. Since the 1500s, mahogany has been a prized timber product—a building block for high-quality furniture and musical instruments—valued for its deep reddish color, durability, and beauty
