Answer:

RecBCD enzyme

Explanation:

RecBCD is an enzyme of the E. coli bacterium that initiates recombinational repair from potentially lethal double strand breaks in DNA which may result from ionizing radiation, replication errors, endonuclease, oxidative damage, and a host of other factors. The RecBCD enzyme is both a helicase that unwinds, or separates the strands of DNA, and a nuclease that makes single-stranded nicks in DNA.

For each of the following statements, indicate whether the statement describes the P generation, F1 generation, or F2 generation.

The plants in the
were allowed to self-pollinate.
The plants in the
are true breeding.
After a cross, there are three times as many tall plants as there are short plants in the
.

Answers

Answer:

The plants that were allowed to self pollinate were the First filial generation, filial, Latin for family. Or just the F1 generation plants.

The plants that are true breeding are Parental generation or for shorthand, the P generation plants.

The plants where there were three times as many tall plants as short plants are in the second filial generation, or the F2 generation.

This question is based on the Mendel’s Experiment.

Sir Gregor Johann Mendel.

Mendel experimented on pea plants and gave the laws for genetics which are a very important aspect of hereditary. Because of his experiment the terms recessive and dominant came into light and how the genes are passed from generations were also studied.

The statements can be completed as:

Plants that were allowed to self pollinate were F1 or the first filial generation.

The true-breeding plants are P (parental) generation.

The plants having the phenotypic ratio of 3:1 for tallness and shortness are in F2(second filial) generation.

The steps can be explained as:

The cross which is the first step between the given alleles of a trait in a cross is called parental (P) generation.

The progenies produced as a result of a cross between the parental traits is called the first filial (F1) generation.

When the traits from the F1 is interbred then a second filial generation (F2) is produced.

What are prokaryotic organisms?

There are three domains of the life the Archaea, the Bacteria, and the Eukarya, in which Archaea and Bacteria belong to prokaryotic cells but eukaryotic cells belong to the Eukarya domain.

Prokaryotic organisms include the organism's absence of a nuclear membrane and not having well-defined cell organelle, this includes bacteria. It is a unicellular organism having an asexual mode of reproduction.

The Eukarya domain includes the eucaryotic cells having a true nuclear membrane, this domain includes all the eukaryote plants the human beings.

Which statement correctly describes the number of chromosomes in body cells and gametes?

Answers

Answer:

its A

Explanation:

Body cells and gametes are both diploid correctly describes the number of chromosomes in body cells and gametes.

What are chromosomes?

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.

Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cells.

One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus.

Which of the following cells is formed by meiosis?
O A. A fertilized egg
O B. A sperm cell
O C. A heart cell

Answers

Answer:

B. A sperm cell

Explanation:

Meiosis creates gametes/sex cells, such as the sperm and egg.

So, sperm cells are formed by meiosis.

Meiosis doesn't create fertilized eggs, it instead creates normal egg cells.

Meiosis also doesn't create heart and bacterial cells because those are made in mitosis.

So, B is the correct answer.
