The basic units that are put together over and over to build a strand of dna are called as nucleotides.

Explanation:

DNA is a heteropolymer that involves many monomers that is the nucleotides that are joined together by phosphodiester bonds in order to develop a complete DNA. The nucleotides consists of nitrogenous bases, phosphate groups and the sugar molecules that are bound together to form a complete nucleotide. The phosphate groups form a backbone through which the nucleotides are joined together.

6.Two apparently normal parents have a daughter who suffers from agammaglobulinemia (AGG), an inherited defect of the immune sys

KATRIN_1 [288]

Answer:

See the answer below

Explanation:

For two normal parents to have produced a daughter who suffers from AGG, it means the disorder is an autosomal recessive trait. In order words, it means the parents are both carrying the allele for the disorder in recessive form.

Let us assume that the allele for the disorder is represented by b, meaning that the alternate form would be B. Both parents will have the genotype Bb and will both appear normal.

Bb x Bb

BB Bb Bb bb

The affected child would be the one with bb genotype while the remaining children would appear normal. See the attached image for the Punnet's square analysis of the cross.

The genotypes of the parent would be heterozygous.

The enzyme that makes new strands of DNA only in one direction is:_______ primase

Wittaler [7]

Answer:

Option C

Explanation:

Primase synthesizes DNA polymerase through the initiation of synthesis of RNA primer. DNA polymerase is able to add nucleotides in only one direction towards the direction of replication fork Hence, it add to the chain only at 3’ end and build new strand from 5’ to 3’ end.

The 5’ to 3’ strand is the leading strand and is easy to build as 5’ to 3’ progresses towards the replication fork and DNA polymerase also move in the same direction

Hence, option C is correct
