Answer:

Option). duplication.

Explanation:

Mutations are permanent changes in DNA, due to change in its nucleotide sequence. A mutation that occurs due to replication or duplication of a portion of genetic material is known as duplication.  

As altered sequence in given bacterium represents duplication of three guanine nucleotides, the type of mutation that caused this sequence change is duplication.

Original sequence: act<u>ggg</u>atcct

Altered sequence:  atcggggggatcct

Thus, the correct answer is 'duplication.'

The answer is B. Warm current move away from the equator towards the poles while cold currents concurrently move towards the equator. This process is known as thermohaline circulation. The cold currents due to higher density move in the great depth of the oceans while the warmer currents are on the surface due to their relatively lower density.

Blababa [14]

Answer:

According to the genetic code, the amino acids are the following:  

- Glycine: encoded by GGC, GGA and GGG codons  

-Arginine: encoded by AGA and AGG codons

-Lysine: encoded by AAA and AAG codons

-Glutamic acid: encoded by GAA and GAG  codons

Explanation:

The probabilities to observe an amino-acid formed by Glutamic acid in the coding sequence is 2/9 for each codon

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid

Which of the following is changed in a reaction by the action of an enzyme?
andrey2020 [161]
Well during an enzyme catalyzed reaction the enzyme bonds with a specific substrate at the active site. This is called an enzyme-substrate complex. The substrate is converted into a specific product, but the enzyme remains unchanged. Enzymes accelerate reactions by factors of at least a million.Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again



Hope it helps
