wlad13 [49]

Answer:

The correct answer is- C. double or single-stranded DNA or double or single-stranded RNA.

Explanation:

All the viruses are intracellular parasites which means they obtain their nutrition from their host. Viruses do not have cellular level of organization. They only have their nucleic acid which is surrounded by a protein coat called a capsid.

The nucleic acid in viruses can be of different types. It can be single or double-stranded DNA or single or double-stranded RNA. Their genome can be linear or circular. They inject their genetic material in their host and introduce it in the host genome. Therefore the correct answer is C.

A gene exists in two alleles, which we will call B and b. The gene is 1123 bp in length, and the B and b alleles exhibit single
Hitman42 [59]

Answer:

The below options will complete the question

Select one:

a. Gap repair synthesis

b. Mismatch repair

c. Direct repair

d. Nucleotide excision repair

Our answer is surely A.

a. Gap repair synthesis

Explanation:

Alleles of gene B differ by 6 bps and are seeming close to each other among the 1123 bp within the particular gene, favouring the gap repair synthesis.

In the gap repair synthesis, a double stranded break is formed at a homologous chromosome with a small part of the gene or the 6 bps of the recessive allele

being digested away.

Strand invasion and a D-loop formation is followed by the new region being occupied by the dominant B allele to yielding dominant B allele in both chromosomes.

The gap repair synthesis allows the 6bps to be converted to the dominant B from the recessive b when in proximity/being close together.

What are the 3 laws of inheritance?
nikdorinn [45]

The three laws of inheritance are :

Law of Dominance. Law of Segregation. Law of Independent Assortment.

what is law of dominance?

First, according to the Law of Dominance and Uniformity, some alleles—variants of a specific gene located at the same chromosomal locus or location—are dominant over other alleles for that gene.

As it relates to genetics, the term "inherited" describes a feature or variation that is encoded in DNA and passed from parent to child during reproduction. The laws of Mendelian genetics govern inheritance. A will needs to be admitted to probate in order for the inheritance procedure to start. The probate court examines the will, approves an executor, and formally distributes assets to recipients in accordance with the terms. The executor will pay off any outstanding obligations of the deceased prior to the transfer

PLEASE HELP (50 POINTS)
baherus [9]

Athletics would be the easiest choice here

Sports are an active that takes up a lot of different organ systems. When running I use my muscular system and cardiovascular system the most. The cardiovascular system directly controls running because it helps prevent me from getting tired and worn out faster.

Hope this helps :)
