Which Summary Below Correctly Describes What Occurs During Transcription

• Yous need to know the basic process of Deoxyribonucleic acid replication and how it relates to the transmission and conservation of genetic information.
• You lot need to know that mutations in the Deoxyribonucleic acid sequence may or may not result in phenotypic change and how mutations in gametes may result in phenotypic changes in offspring.
• Yous need to know the bones processes of transcription and translation and how they event in gene expression. You will besides need to know that the bones processes of DNA are universal in organisms.
• You demand to know that similarities in the genetic codes of organisms are due to mutual ancestry and the procedure of inheritance.

Genes for medically of import proteins can exist cloned and inserted into bacteria, as shown in the diagram below.

Why can leaner recognize a human factor so produce a human protein?

A. Dna replication in bacteria and humans is the same.

B. Bacterial cells comprise the same organelles as homo cells.

C. The basic components of Dna are the same in humans and bacteria.

D. Bacterial cells and human being cells contain the aforementioned kind of chromosomes.

At what point in the cell cycle does Deoxyribonucleic acid replication occur and why?

A. before a cell divides, to provide each of the ii resulting cells with a consummate set of Deoxyribonucleic acid instructions

B. before a cell divides, to ensure that the DNA will fit into the resulting cells

C. during cell sectionalisation, to ensure that the DNA volition fit into the resulting cells

Which of the following would nearly probable cause a mutation?

A. the placement of ribosomes on the endoplasmic reticulum

B. the insertion of a nucleotide into Deoxyribonucleic acid

 A diagram of a cellular procedure is shown below.

Which of the following identifies the process shown at point Z?

A. Translation

B. Translocation

C. Replication

D. Transcription

CLICK HERE FOR ANSWER

During transcription the Deoxyribonucleic acid base of operations sequence is transcribed into a complimentary mRNA sequence. A codon table like the one shown beneath lists the amino acids coded for by particular triads of mRNA bases. A segment of DNA has undergone a mutation in which one nucleotide has been changed. The original sequence was ACG and the new sequence is ACA. Use the codon table to determine whether or not this mutation volition cause a alter in the phenotype of the organism.

A. yep, the phenotype of the organism would change because a new amino acid volition be coded for.

B. aye, the phenotype of the organism would change considering any change in the DNA sequence will crusade a change in phenotype.

C. Even though the Dna sequence changed, the sequence even so codes for the same amino acid, then no modify in phenotype will occur.

D. It is impossible to determine if a alter in phenotype will occur using only the DNA sequence.
