The lagging strand is characterized by a series of short segments of DNA (Okazaki fragments) that will be joined together to for

m a finished lagging strand. The experiments that led to the discovery of Okazaki fragments gave evidence for which of the following ideas? The lagging strand is characterized by a series of short segments of DNA (Okazaki fragments) that will be joined together to form a finished lagging strand. The experiments that led to the discovery of Okazaki fragments gave evidence for which of the following ideas? DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication. DNA is the genetic material. DNA is a polymer consisting of four monomers: adenine, thymine, guanine, and cytosine. Bacterial replication is fundamentally different from eukaryotic replication.

The correct answer is: DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication

DNA polymerase is an enzyme that synthesizes DNA during the DNA replication by adds nucleotides to the 3’ end of a primer. This means that the new chain is formed in a 5’ → 3’ direction.

Because double-stranded DNA is antiparallel, DNA polymerase moves in opposite directions on the two strands-leading and lagging strand. The leading strand is copied continuously since DNA polymerase is moving towards the replication fork.  The lagging strand is copied discontinuous. DNA polymerase is moving away from the replication fork (and helicase that separates the strands), so it must constantly return to copy newly separated stretches of DNA. So,  the lagging strand is copied as a series of short fragments-Okazaki fragments that are joined together by a combination of DNA pol I and DNA ligase.

How do birds digest their food in the absence of teeth?
vodka [1.7K]

Answer:

They have a gizzard to grind the food.

Explanation:

Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.

For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.

Which amino acid chain would be produced by the dna base sequence below?
Oliga [24]

In DNA, there is a code for the sequence of three bases for the placement of certain amino acid in a protein chain.<span> The amino acid chain that can be produced by the DNA base sequence of C-A-A-G-T-T-A-A-A-T-T-A-T-T-G-T-G-A would be based on the DNA code CAA is valine, GTT is glutamine, AAA is phenylalanine, TTA is asparagine, TTG is asparagine and TGA is threonine. </span>
