How is synthesis of a Repressible enzyme stopped?

Repressor must bind to the operator. Substrate must bind to the repressor. Synthesis of a repressible enzyme is stopped by. The end-product binding to the promoter.

What is an enzyme that copies DNA to make a molecule of RNA?

RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.

Which of the following genetic elements is transcribed into a single mRNA?


Term Which of the following genetic elements is transcribed into a single mRNA? Definition The structural Gene
Term What makes mRNA from the information stored in a DNA template? Definition RNA Polymerase
Term Ribosomes contain which kind of RNA? Definition rRNA

What are the 3 stages of DNA replication?

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

Which enzyme is responsible for facilitating?

DNA replication?

Question Answer
Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new DNA molecule? Polymerase
Which enzyme is responsible or creating the covalent bonds that connect the sugar phosphate backbone of the new DNA molecules? Ligase (polymerase)

What is the builder enzyme?

What is the “builder enzyme” ; replicates DNA molecules to make new strands of DNA? Primase.

Are the 2 strands of DNA identical?

Both strands of double-stranded DNA store the same biological information. This information is replicated as and when the two strands separate. A large part of DNA (more than 98% for humans) is non-coding, meaning that these sections do not serve as patterns for protein sequences.

What is the gluing enzyme?

Though meat glue may sound scary, transglutaminase is an enzyme that’s found naturally in humans, animals and plants. As its nickname suggests, it acts as a glue, holding together proteins found in common foods like meat, baked goods and cheese.

How does DNA get built?

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
