Webb18 nov. 2024 · Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In … Webb1 juni 2024 · DNA polymerase III binds to the primer and creates a short segment of newly synthesized DNA from 5′-3′, synthesizing in the opposite direction of the replication fork. This is the first Okazaki fragment. As helicase further unwinds the double helix and the replication fork moves down the strand, another primer is added closer to the fork.

Lagging strand: Strand that cannot be continuously synthesized from 5’ → 3’ and is instead synthesized in fragments and requires a little help from ligase. Key enzymes: 1. Helicase: Unzips the DNA so the other enzymes can access the nucleotide … WebbHDL. Lipoproteins are a lipid + a protein (compound lipid). Because lipids are less dense than water, the density of lipoproteins decreases as the proportion of lipid to protein increases. Lipoproteins have a major role in lipid and cholesterol transport and metabolism. Lipoproteins are classified based on their density and composition. WebbThe process is quite rapid and occurs with few errors. DNA replication uses a large number of proteins and enzymes ( Table 11.1 ). One of the key players is the enzyme DNA polymerase, also known as DNA pol. In bacteria, three main types of DNA polymerases are known: DNA pol I, DNA pol II, and DNA pol III. our people physiology
