Which of the following is not true of a codon?

Biology
1 answer:
ratelena [41]3 years ago
5 0

Answer:

It extends from one end of a tRNA molecule. (Ans. C)

Explanation:

Codon or genetic code, the sequence of nucleotides in DNA and RNA which determines the amino acid sequence of the proteins. The linear sequence of nucleotides present in DNA has the information for protein sequence, proteins are not directly synthesized from DNA, an mRNA molecule is synthesized from DNA and complete the formation of proteins.

RNA is composed of 4 nucleotides adenine, cytosine, uracil and guanine. Three nucleotides constitute a unite which is called Codon, which helping to codes the amino acids. Example AUG is a codon that specifies the amino acid methionine. It is found at the starting of every mRNA and indicates the start of a protein.

There are 64 codons, 3 of them are not coding for an amino acid but indicate the end of the protein, the remaining 61 codons specify the 20 amino acids which help in makeup the proteins.

The false spider mite, Brevipalpus phoenicis, has only two chromosomes. Which of the following pieces of evidence would allow yo
Reptile [31]

Answer:

The correct answer is - a. If these two mite chromosomes have different genes at different loci.

Explanation:

If it is 2n= 2, it means that it is diploid and has two sets of chromosomes in which one set comes from mother and the other from father which means parent's genes contribute to diploid equally. Both sets of chromosomes form homologous chromosome pair. Each homolog of the pair has the same gene at the same loci in diploid and if it has not the same homologous gene at the same loci these are haploid.

Which of the following is a true statement?Anabolic pathways build molecules, require energy, and are endergonic.Anabolic pathwa
expeople1 [14]

Answer:

A: Anabolic pathways build molecules, require energy and are endergonic

Explanation:

Anabolism and catabolism are the two important process of metabolism - a process through which cells get energy to drive various processes within the body and get rid of toxic wastes.

Anabolic and catabolic reactions can be described as opposing sides of the same coin. While anabolism refers to the various reactions that build up molecules within the cell, catabolism has to do with the breakdown of big or complex molecules into smaller ones.

Both processes involves energy. Anabolic reactions require energy to drive the building up process and therefore referred to as endergonic reactions. On the other hand, catabolic reactions liberate energy during the breaking down of complex molecules and therefore referred to exergonic reactions.

A good example of anabolic reaction is photosynthesis which involves the building up of carbohydrate (glucose) using carbon-dioxide, water molecule and energy while a good example of catabolic reaction is respiration which involves the breakdown of carbohydrates into carbon-dioxide, water molecules and the release of energy.

Hence, the only correct option is A.
