Answer:

D. A Sequence of three amino acids linked by peptide bonds.

Explanation:

Well, it cannot be A or C because those answers contain the letter T, otherwise, know as Thymine. Thymine is only found in DNA sequences, not it RNA. RNA sequences replace Thymine with Uracil, which brings me to the next point. It can't be answer choice B. because it contains an error in translation. The 3rd and 4th letter in, CG should translate to GC in the RNA strand, but it doesn't. This is why your answer is D.

Hope I helped!

Answer:

The correct answer is d. a sequence of three amino acids linked by peptide bonds.

Explanation:

Translation is the process of making proteins with the help of the cell's machinery. mRNA contains the sequence of codons that code for amino acids. Three codons are required to code a single amino acid. Ribosomes attach to mRNA and move forward codon by codon to read the codon sequence.

Ribosomes allow the binding of specific tRNA which have correct anticodon sequence and attached amino acid according to the triplet codon present on mRNA. So tRNA add amino acids in the polypeptide chain.

Therefore during translation of DNA sequence AAGCTGGGA, a sequence of three amino acid will be linked by peptide bond because the sequence have 9 triplet codon and each will code for one amino acid.

Answer:

It is the necessity of the living organisms to increase their number in order to maintain the continuity of the species. Reproduction is the process through which one organism give rise to a similar organism of its own kind. It is one of the most important characteristics of the living organism.

Complete question:

A researcher had 15 pure-bred wild mice which were brown and all were females. They were all mated with a male called Bob. All the offspring were brown. These were then crossed among themselves with the following results: 293 brown and 115 white.

(i). Determine the color of Bob.

(ii). Determine which color is dominant.

(iii). Work out the ratio of brown to white in the ‘grandchildren.’

(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring.

Use the Punnett square to work out your answers

Answer:

(i). Determine the color of Bob. BOB IS WHITE

(ii). Determine which color is dominant. BROWN IS DOMINANT

(iii). Work out the ratio of brown to white in the ‘grandchildren.’

PHENOTYPIC RATIO BROWN TO WHITE 3:1

(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring. THE WHOLE PROGENY WILL BE WHITE

A DNA sequence is shown. AAT - CCG - GTG Which sequence best shows the result of a substitution mutation in the DNA?

kotegsom [21]

Mutations are sudden spontaneous random changes that occur in the genetic make up of an organisms. A substitution mutation is a type of mutation that exchanges one base for another, for example a change in a single base such as switching an A to a G). Substitution could cause a change of codon to one that encodes a different amino acid and cause a small change in the protein produced. In the above sequence AAT-CCG-GTG in substitution of a single base
