If the DNA sequence is --- AAA TAT CCG TAG CAA ATG, write the mRNA sequence, tRNA anticodon sequence, and the six amino acids for this.

Answers

adenine(A) binds with uracil(U)

Thymine(T) binds with Adenine(A)

guanine(G) binds with cytosine(C)

The complementary mRNA, which contains the codons is

UUU AUA GGC AUC GUU UAC

The complementary tRNa , which contains the anticodons is

AAA UAU CCG UAG CAA AUG

The six aminoacids are

phenylalanine-isoleucine-glycine-isoleucine-valine-tyrosine

The bases tend to exist as a pair in the DNA’s double helix structure. The bases are bonded by hydrogen bonds.

Their bonds are mentioned as follows:

Adenosine (A) is paired with thymine (T) Cytosine (C) is paired with guanine (G)

However, the base thymine (T) is present only in the nucleotide of DNA and the base uracil (U) is present only in the nucleotide of RNA.

Based on the understanding of the nucleotide and central dogma concepts, the following sequences are determined:

DNA Sequence:               AAA TAT CCG TAG CAA ATGmRNA Sequence:            UUU AUA GGC AUC GUU UACtRNA anticodon:              AAA UAU CCG UAG CAA AUGSix amino acids:              PHE ILE GLY ILE VAL TYR

Six amino acids are namely Phenylalanine, Isoleucine, Glycine, Isoleucine, Valine, and Tyrosine.

Thus, the DNA sequence is used to determine the other RNA sequences and amino acids.

Every monarch butterfly migrates. This statement _______. A) is true B) can be made true by change "Every" to "No" C) can be made true by deleting "monarch" D) can be made true by changing "Every" to "The final generation

Answers

Answer:

The answer is option A "Is True"

Explanation:

The Monarch is notable for its capacity to travel significant stretches, and the migrations in North America are one of the best common marvels on the planet. This butterfly is additionally periodically recorded from the English Isles, making it our biggest and most extraordinary traveler butterfly.

Each fall, a great many ruler butterflies move 3,000 miles from their favorable places in northeastern North America to spend the colder time of year in the timber lands of southwestern Mexico. Every movement is by new generation, so they can't gain from others. All things being equal, they depend on their qualities. Their antennae have a genetic clock that reveals to them when to move and to explore they measure the sun's situation not too far off with their eyes.

What is amino acid?

Amino acids are molecules that form proteins when they combine. The building blocks of life are amino acids and proteins.

Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.

A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).

There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.

The amino acid sequence for the given template will be:

3' AGGUUACCGAAUAAACGU 5'

So, as per three letter code, the amino acid chain will be:

Arginine – Leucine - Proline – Asparagine – Lysine – Arginine

Thus, the correct option is A.

Describe the steps of protein synthesis in a eukaryote.

Answers

The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.

The second step is  translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.

Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.

What is protein synthesis in a eukaryote?

The mRNA exits the nucleus and attaches to a ribosome in the second step of translation. Protein synthesis takes place in ribosomes. An amino acid is created for every three nitrogenous bases in the mRNA.

Transfer RNA transports amino acids to the location where proteins are synthesized. We are left with a polypeptide after this procedure.

The primary level of regulation of eukaryotic gene expression is transcription.

Therefore, the process of transcription involves an enzyme-producing messenger RNA (RNA-polymerase).

On February 21, a student observes that the Moon cannot be seen in the clear night sky. The date when the student is not able to see the Moon again is on March 21. The correct option is D.

What is the moon?

The moon is the only natural satellite of the earth. It is white and gray and visible from the earth on nights only. It is the fifth-largest satellite in the solar system.

The moon has different phases seen from the earth because the moon revolves around the sun. The four phases have been named full moon, no moon, C moon, and half moon.

In 28 days, the moon is not visible for one day, then the other day it is visible and C-shaped. The student was seen on February 21.

21 + 27 day means 21 march.
