Im not sure cuz why theres O in there? I thought there’s only 4 bases Adenine Thymine Guanine Cytosine and in RNA there’s Uracil instead of Thymine. Sorry
Answer:
D. changing the DNA of a living thing to change its characteristics.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits.
Answer:
64.
Explanation:
It is 64 because there are 20 amino acids with four bases ( A,T,C and G).
and genetic code can be read in triplets and also the four bases can occupy the positions. Eachh amino acid can be coded by the triplet codons. A triplet codon shows three nucleotides of the mRNA template that can code for amino acid
Therefore the number of codons is 4×4×4= 64.
Answer:
The carbon dioxide reacts with water to form carbonic acid.
Explanation:
CO2+H2O=H2CO3
In this reaction carbon dioxide(CO2) and water(H2O) act as reactant to form carbonic acid(H2CO3) which is a weak acid.
The above reaction is an important reaction carried out by bicarbonate buffer system to maintain normal acid base balance inside our body but this buffer system includes an additional reaction in with carbonic acid is ionized to form H+ and HCO3- ion or bicarbonate ion.
This condensation reaction is similar to that in which a peptide bond is formed between two amino acids (Chapter 3). Thus a single nucleic acid strand is a phosphate-pentose polymer (a polyester) with purine and pyrimidine bases as side groups. The links between the nucleotides are called phosphodiester bonds
