What else can I help you with?
Which type of enzyme ensures that the correct base for growing the chain is aligned with the template chain?
DNA polymerase is the enzyme responsible for ensuring that the correct base is aligned with the template chain during DNA replication. It has a proofreading function that helps in accurately replicating the DNA sequence.
In relation to protein what is called for when DNA bases are combined in different triplets?
When DNA bases are combined into different 3-base codes, called triplets or codons, different amino acids are called for to create the protein chain.
What happens to the amino acids in the chain if the fourth base is changed in the DNA?
TRNA
What is the segment of a DNA chain that codes for all or pert of a trait?
The segment of a DNA chain that codes for a trait is called a gene. Genes contain instructions for making proteins, which are responsible for determining an organism's traits such as eye color, height, and susceptibility to certain diseases.
What is responsible for sending a message from DNA to communicate with tRNA?
mRNA carries a copy of the instructions from the DNA in the nucleus to the ribosomes, where protein synthesis occurs. It is the codons (3-base codes) on the mRNA which bind to the tRNA to ensure that the correct amino acid is added to the chain.
A DNA strand with the base sequence tgacgca codes for a strand of mrna the mrna will have what base sequence?
The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.
What is the connection between base triplets and codes?
Base triplets are the building blocks of codons in DNA. Each base triplet, consisting of three nucleotides, corresponds to a specific amino acid or a stop signal in the genetic code. This relationship between base triplets and codes allows for the translation of DNA sequences into proteins.
The triplet codes needed to specify a specific polypeptide chain are found in the?
The triplet codes needed to specify a specific polypeptide chain are found in the mRNA (messenger RNA) during the process of translation. These triplet codes, known as codons, determine the sequence of amino acids that will be incorporated into the polypeptide chain.
What is region of nucleotide to which the nitrogen base is attached in DNA?
Deoxyribose (the chain of alternating sugar/phosphate links)
The DNA base sequence GGG codes for the amino acid proline. Could this same base sequence code for a different amino acid Why or why not?
Yes because once an amino acid is added to the protein chain, the transfer RNA is released into the cytoplasm and can pick up another amino acid.
In any double chain of DNA the nucleotide adenine A matches up with which nucleotide?
In a double chain of DNA, the nucleotide adenine (A) pairs with thymine (T) via complementary base pairing.
What substance are genes made?
There are three parts. A pentose sugar,phosphate group and a nitrogenous base.
