Answer:

I think the main reasons why Biodiversity is under serious threat is as a result of human activities. The main dangers worldwide are population growth and resource consumption, climate change and global warming is also a big reason. Habitat conversion and urbanisation, invasive species that dont belong, over-exploitation of natural resources and environmental degradation.

8_murik_8 [283]

Answer:

The correct answer is: C. third nucleotide position.

Explanation:

  • Genes located on the chromosomes encodes for proteins.
  • A Gene is made up of a  Deoxyribonucleotide (DNA) sequence which is transcribed into the messenger Ribonucleotide (mRNA) sequence by the help of RNA polymerase.
  • This mRNA sequence is further translated into the amino acid sequence, that folds to form the functional protein, by the help of the Ribosome.
  • The Ribosome reads the mRNA sequence in the form of triplets (three nucleotide together) and each such triplet nucleotide codes for an amino acid.
  • Each such triplet nucleotide is known as a Codon.
  • The Genetic Code is a table which represents the  amino acid encoded by each codon.
  • However, the Genetic Code is degenerate in nature. This means that one amino acid can be coded by more than one codon.
  • This is because, among the the three nucleotide positions in a codon only the first two determine the specificity of the amino acid while the third nucleotide, also called the wobble nucleotide, is not specific. Presence of any nucleotide in the third position of the codon will not alter the amino acid encoded by the codon.
  • In the given question, organisms producing homologous protein have similar amino acid sequence but they vary in the corresponding nucleotide sequence of the gene which codes for the homologous protein.
  • This is because at the nucleotide level the variation lies in the wobble nucleotide position that occupies the third position in the codon.

Lina20 [59]

Answer:

B) a sequence of three nucleotides

Explanation:

A codon is the sequence of three nucleotides that decide that which particular amino acid would be incorporated in the polypeptide chain. Each codon code for a particular amino acid and responsible for the primary structure of proteins.

During translation the transfer RNA have the anticodon on its one side and amino acid bound to it on its other side. It adds the amino acids to growing polypeptide chain by binding to particular codon on messenger RNA.

Example; AUG is the starting codon for every protein and code for methionine in eukaryotes and anticodon for it is UAC.
