Question

dna and protein synthesis
dna is the keeper of the genome. within its sequence of nitrogenous bases is the code of life, the instructions for making every protein the organism needs. dna is made up of nucleotides which include a deoxyribose sugar, a phosphate group, and a nitrogen - containing base. the bases in dna are adenine, thymine, guanine, and cytosine
figure 1. dna structure
dna cannot leave the nucleus of the cell, but a segment of dna can be copied into mrna in the process of transcription. the mrna can then carry the code to the ribosome where it is translated into a series of amino acids, and a protein is made. a codon is a group of three bases in mrna that code for a particular amino acid. by reading the mrna, amino acids are put in place according to the genetic code provided by the organisms dna. the structure of dna, encoding its many base pairs, determines the structure of all the proteins that organisms produce
the structure of dna determines the structure of proteins. peaches is a one - in - three - million orange lobster caught off the coast of maine and donated to the university of new england for study. she recently had 40 offspring that share her unique coloration. in the wild, lobsters usually have a mottled brown shell. however, lobsters can have color abnormalities due to the mutation of genes, affecting the proteins that bind to their shell pigments. indicate the order of events that cause peaches and her offspring to have orange shells

peaches mutated dna is passed on to her offspring in reproduction.
mutated dna is transcribed into mrna
a protein is made that causes a different colored shell
there is a mutation in a sequence of peaches dna
the mutated sequence causes a different amino acid to be put into the protein sequence
mrna is translated at the ribosome

Explanation:

First, a mutation occurs in Peaches' DNA sequence. Then, this mutated DNA is transcribed into mRNA. The mRNA is translated at the ribosome. The mutated sequence causes a different amino - acid to be put into the protein sequence. A protein is made that causes a different - colored shell. Finally, Peaches' mutated DNA is passed on to her offspring in reproduction.

Answer:

1. There is a mutation in a sequence of Peaches' DNA.
2. Mutated DNA is transcribed into mRNA.
3. mRNA is translated at the ribosome.
4. The mutated sequence causes a different amino acid to be put into the protein sequence.
5. A protein is made that causes a different colored shell.
6. Peaches' mutated DNA is passed on to her offspring in reproduction.
