The lagging strand runs in a _________ direction and is replicated _________.

e-lub [12.9K]

The lagging strand runs in a 5’ to 3’ direction and is replicated discontinuously.

<h3>Why a discontinuous or delayed tape?</h3>

The other strand, called delayed, is replicated discontinuously. In this case, the presence of Okazaki fragments is necessary, small pieces of DNA that will bind to form a new strand. - DNA is degraded by two types of enzymes.

The ends of a DNA strand are classified as 5' and 3', as they correspond to the carbon number of the pentose where the phosphate and hydroxyl (OH) group are located, which join in a phosphodiester bond.

Meiosis Foldable Activity 515.2

Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

homologs pair off into bivalents
At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I forming bivalents; tetrads are formed.
Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

What happens to the bunny population if a friend is never added? What happens when you add a friend

pochemuha

While pet rabbits can survive alone without another bunny living with them, they can get very lonely and sad, as rabbits are naturally herd animals. No matter how much human attention they receive, that does not replace attention from a fellow rabbit friend.

When one rabbit is introduced to another rabbit, they may not always get along. However, they will always be very curious when they first meet, and can become close friends after bonding for a while. Keeping close supervision on bunnies when they first meet, however, is very crucial, as they could get into a fight and hurt each other.
