What 2 enzymes are used during DNA replication? describe what each does during replication
polet [3.4K]

The two enzymes that are used during DNA replication is helicase and polymerase. Each enzyme has distinct role that made it a vital part of the replication. In the course of DNA replication, the initial stage is to unzip the double helix structure of the DNA molecule by the enzyme helicase, which breaks the hydrogen bonds that holds the complementary bases of DNA.

Moreover, the DNA polymerase has the ability to exactly copy a DNA template. This enzyme binds to the leading strand and then adding a new complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

The picture shows the dihybrid cross of 2 guinea pigs.
kramer

Picture from another source is attached

Answer:

1. BbRr

2. Black, rough fur

3. bbRR

Explanation:

1. The genotype of the parents can be seen at the top of the cross "BbRr". The genotype is what alleles the parents have. In this case, it is the alleles of two different genes - for color and texture of fur. The genotype gives rise to 4 possible allele combinations that an offspring can inherit (BR, Br, bR or br)

2. The dominant allele is usually displayed as a capital letter, and the recessive as lowercase. Without further information, we will assume this is the case. The parents are heterzygous for both traits, meaning they each carry a dominant and recessive allele for both traits. That means the dominant allele will be expressed in the phenotype. Therefore, the guinea pigs will have black, rough fur.

3. Empty box shown in the attachment. We simply read the column and row  of alleles that are contributing to this offspring's genotype. We can see looking at the square that from one parent (top) the baby will inherit bR, and from the other parent (left) it will inherit bR as well. This means the baby's genotype will be bbRR
