How does DNA Replication work

Biology
1 answer:
elixir [45]3 years ago
3 0

"The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands"(https://www.nature.com/scitable/.../cells-can-replicate-their-dna-precisely-6524830).

The building blocks or monomers of nucleic acid molecules are called _____. See concept 5.5 (page 84) view available hint(s) the
Monica [59]

Answer;

-Nucleotides

Explanation;

-Nucleic acids are polynucleotides, that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

-A sugar-phosphate backbone joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

Briefly describe asexual reproduction in plants
AysviL [449]

Asexual reproduction requires only one parent. Since there is only one parent, there is no exchanging of genetic information, and the offspring are clones of the parent. Asexual reproduction in plants can occur in a variety of forms, including budding, vegetative propagation, and fragmentation. Let's discuss these reproduction types.

Have you ever found an old potato hidden in the back of a cabinet in your kitchen? If a potato sits around for a long time, it will have many small growths, commonly referred to as 'eyes'. Each of these sprouts can be cut from the potato and planted. They will grow into a clone of the original plant that produced the potato. This is a classic example of budding.

For an example of vegetative propagation, let's look at the strawberry plant. If you plant strawberries, you will notice that a row of plants will quickly spread into a large mass of plants. This is because they do a type of vegetative propagation by producing runners. Strawberry plants send out horizontal stems known as stolons. These stems will work their way into the ground in places and form roots, and eventually a new plant will grow.

A third type of asexual reproduction in plants is called fragmentation. This type of asexual reproduction is often used by nurseries and greenhouses to produce plants quickly. For many plants, a clone can be created by breaking off a portion of the stem and placing it in soil or water, depending on the plant. This also happens naturally when small parts of a plant fall off onto the soil and begin to grow into a new plant. An example of fragmentation occurs in liverwort plants, whose small stems or leaves are often broken off by animals or wind and then grow into clones of the parent plant when they land in the soil. I hope this helps
