Please answer the following questions correctly​
Oksi-84 [34.3K]

Answer:

i.   Name each of the parts labelled I, II, III, IV and V.

                           {5 marks}

I - Crown / Enamel

II - Dentine

III - Cement / Periodontal membrane

IV - Jaw bone / Root

V - Pulp Cavity

ii   What is the function of each of the parts labelled I and III?

                    {2 marks}

I - Protects teeth from harmful bacteria

-- Enable teeth withstand pressure of chewing

-- Cutting / chewing / protects dentine / protect pulp cavity

III - hold tooth firmly (in socket / Jaw bone)

iii  Which of the labelled parts could be affected by tooth decay?

                                   {1 mark}

V - Pulp cavity

iv  State three ways by which tooth decay may be prevented.

                      {3 marks}

→ avoid using sharp-pointed objects

→ avoid having dry mouth

→ use water containing fluorides to wash teeth / mouth

→ avoid smoking

→ the teeth should be cleaned regularly after each meal / remove food particle from the teeth / flossing

→ wash the mouth vigorously after each meal

→ regular visit to the dentist

→ avoid eating too hot foods

→ avoid eating too much sugary food

→ avoid eating too cold food / taking too cold drinks

What protein is responsible for the initial step in unwinding the DNA helix during replication of the bacterial chromosome?
maw [93]

Answer:

Proteins play a fundamental role for life and are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge amount of different functions.

The passage of DNA to proteins begins with the step of transforming genetic information into an intermediary between DNA and protein. This intermediary is called messenger RNA (mRNA). The difference between DNA and mRNA is that the second corresponds to a very small fraction of all DNA, consists of a single chain (it is no longer a “zipper” but a strand), and that Thymine (T) is replaced by the Uracil (U). This fraction corresponds to the stretch of DNA that contains the sequence necessary to ultimately synthesize the protein.

Several organisms have a homologous protein (inherited from a common ancestor) that is highly similar at the amino acid level. Y
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.
