Which nitrogen base sequence is the partner of Tcagca quizlet?

Which nitrogen base sequence is the partner of Tcagca quizlet?

Answer: Adenine pairs with Thymine and Cytosine with Guanine. Thus : A-G-T-C-G-T is the correct answer.

Which amino acid will be carried to a ribosome?

tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges,” matching a codon in an mRNA with the amino acid it codes for.

What are the nitrogenous bases attached to?

Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)). These nitrogenous bases are attached to C1′ of deoxyribose through a glycosidic bond. Deoxyribose attached to a nitrogenous base is called a nucleoside.

What is the complementary messenger RNA sequence for the DNA sequence?

mRNA is formed as a complementary strand to one of the two strands of the DNA. Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine.

What do the G and A represent in the DNA sequence?

ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). Adenine pairs with thymine, and cytosine pairs with guanine. The sequence of bases in a portion of a DNA molecule, called a gene, carries the instructions needed to assemble a protein.

How do you read a mRNA sequence?

Codons in an mRNA are read during translation, beginning with a start codon and continuing until a stop codon is reached. mRNA codons are read from 5′ to 3′ , and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus.

How do you know to end the translation process?

Translation ends in a process called termination. Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) enters the A site. Stop codons are recognized by proteins called release factors, which fit neatly into the P site (though they aren’t tRNAs).

Which steps in translation are blocked by tetracyclines and macrolides?

Macrolide antibiotics inhibit translation by binding in the ribosomal nascent peptide exit tunnel. It was believed that macrolides interfere with protein synthesis by obstructing the egress of nascent proteins.

Which step in translation is blocked by tetracyclines?

Many studies have indicated that the tetracyclines bind to the RNA component of bacterial ribosomes. More specifically, they are believed to inhibit translation by binding to the 16S rRNA and inhibiting the binding of aminoacyl-tRNA to the mRNA-ribosome complex (7, 8).

What are the basic steps in the translation process?

There are three major steps to translation: Initiation, Elongation, and Termination. The ribosome is made of two separate subunits: the small subunit and the large subunit. During initiation the small subunit attaches to the 5′ end of mRNA. It then moves in the 5′ → 3′ direction.

Which step in translation does not require energy?

A peptide bond is formed between COOH group of the t-RNA at P-site and NH, group of aminoacyl t-RNA. This is facilitated by the enzyme peptidyl transferase and does not require high energy phosphate bonds.

Which state of translation does not consume high energy phosphate bond?

So, the correct answer is ‘Peptidyl transferase reaction’.

Does translation occur in the rough ER?

Ribosomes on the rough endoplasmic reticulum are called ‘membrane bound’ and are responsible for the assembly of many proteins. This process is called translation. It is in the rough ER for example that four polypeptide chains are brought together to form haemoglobin.

What is the three base sequence on mRNA called?

codon

How many codons are needed to specify three amino acids?

Three codons

How many codons are needed for 1 amino acids?

Because there are only 20 different amino acids but 64 possible codons, most amino acids are indicated by more than one codon. (Note, however, that each codon represents only one amino acid or stop codon.)

How many codons are required for one amino acid?

The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

How many bases are needed to specify one amino acids?

three bases

How many codons are needed for six amino acids?

The “6 codons” could be interpreted as referring to a run of 6×3 = 18 nucleotides in the mRNA. Then, of course, the answer is trivially, 6 amino acids….How many codons are needed for each amino acids?
