Answer:
step 1: mRNA attaches to the ribosome
step 2: tRNA's attach to free amino acids in the cytoplasmic "pool" of amino acids
step 3: tRNA carries its specific amino acid to the ribosome
step 4: tRNA "delivers" its amino acid based on complementary pairing of a triplet code (anticodon) with the triplet code (codon) of the mRNA
step 5: Enzyme "hooks" the amino acid to the last one in the chain forming a peptide bond
step 6: Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain
Translation in biology involves converting the mRNA transcript, which comes from DNA, into a protein through six stages: Initiation, tRNA elongation, amino acid bonding, mRNA shift & release, arrival of the next tRNA, and termination with a 'stop' codon.
In biology, the process of translation converts the sequence of codons in mRNA, obtained from DNA transcription, into an amino acid chain or a protein. This process occurs in six primary steps:

The mutated DNA is TAC CTC ACT GAG CGT.
What is the impact of this particular mutation on the organism? In order to find out, you need to transcribe and translate the codons.
Answer:
The mutation that involves the change in the sequence of DNA bases is reflected both in the transcription of mRNA and in translation, giving rise to an alteration in the protein, which may not function and whose impact on the organism is a morphological or functional alteration.
Explanation:
According to this scenario, the DNA has experienced a mutation by changing the sequence by one of its bases, Cytosine by Thymine, producing in the mRNA a termination codon that interrupts the normal synthesis of the protein, preventing that protein from fulfilling its function. This particular mutation is called Nonsense mutation.
For normal DNA
DNA TAC CTC ACC GAG CGT
mRNA AUG GAG UGG CUC GCA
Protein Met - Glu - Trp - Leu - Ala
For the mutated DNA
DNA TAC CTC ACT GAG CGT
mRNA AUG GAG UGA CUC GCA
Protein Met - Glu - STOP - Leu - Ala
The change of a cytosine by Thymine in the mutated DNA produces that the third codon of the mRNA is altered, encoding a UGA termination codon, which prematurely stops the protein synthesis and originates an incomplete protein, probably not functional, whose impact in the organism is a morphological or functional alteration.
The correct answer is H. transcribing information in the DNA sequence for the use by the cell
Explanation
The process shown in the image is DNA transcription, this is the first procedure in gene expression. In this process, the information contained in the DNA sequence is transferred to the protein sequence using various RNAs as intermediaries. During this, DNA sequences are copied to RNA by an enzyme called RNA polymerase that synthesizes messenger RNA (maintains DNA sequence information for the use by the cell), so DNA transcription could also be called messenger RNA synthesis. According to the above, the correct answer is H. Transcribing information in the DNA sequence for the use by the cell.
The abnormal gene must have been located on the Y chromosome which is responsible for baby boys hence all his sons had the abnormal condition while none of his daughters had the condition.
Genes are the units of inheritance located on the chromosomes. Since the genes are located on the chromosomes, the chromosome involves determines what traits are transmitted.
For the porcupine man, the abnormal gene must have been located on the Y chromosome which is responsible for baby boys hence all his sons had the abnormal condition while none of his daughters had the condition.

Answer:
THE DOMINANT GENE CAME FROM THE FATHER TO ONLY THE SONS THE RECCESIVE GENE WENT TO HIS DAUGHTERS
Explanation:
B. Restriction fragments are separated.
C. Restriction enzymes are used to cut DNA into fragments.
D. DNA fragments containing repeats are labeled with radioactive probes.
Answer:
(D). DNA fragments containing repeats are labeled with radioactive probes.
Explanation:
DNA fingerprinting can be defined as a process, which involves identification of DNA characteristics of an organism as unique in all organisms as fingerprints.
There are total five steps in DNA fingerprinting, which includeisolation of DNA from the cells, digestion of DNA with restriction enzymes, separation of DNA fragments in agarose gel, transfer of DNA fragments to a blotting paper, and labeling of DNA fragments with radioactive probes of specific sequence to see the results.
Thus, the correct answer is option (D) as represents that last step of DNA fingerprinting.
B. Mutation
C. Independent assortment
D. Random fertilization
E. All of the above
Answer:
The correct answer is E. All of the above
Explanation:
Variation in offspring can be contributed by many different events that change the DNA sequence in gametic cells. These events are crossing over, mutation, independent assortment, and random fertilization.
During the gamete formation, the different genes are assorted independently from the other gametes which results in forming various possible combinations of genes in a gamete increasing the genetic variation.
Crossing over occurs during meiosis between the homologous chromosome that results in exchange of genetic material that brings genetic variation in gametes. During random fertilization, the two gametes fuse and genetic material of two different individual comes to make an offspring which forms a genetical different offspring.
Mutation in the gametic cell is transferred to the offspring during fertilization. Therefore all contributes to variation in offspring produced by sexual reproduction.
