tRNA uses (anticodons/codons) to match to the mRNA.

Answers

Answer:

anticodons

Explanation:

codons are for mRNA

tRNA uses anticodons to match to the mRNA.

Which one does tRNA uses?

tRNA (transfer RNA) molecules are responsible for carrying specific amino acids to the ribosomes during protein synthesis.

They have an anticodon region that consists of three nucleotides that are complementary to the codons on the mRNA (messenger RNA). The codons on the mRNA determine the sequence of amino acids in the growing polypeptide chain.

The anticodon on the tRNA base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing protein chain. The matching between the anticodon and codon is essential for the accurate translation of genetic information into protein synthesis.

A man and a woman have a child together. The mother's blood type is type O and the child's blood type is type A What could the father's genotype be?

Answers

Answer:

iAiA or iAi = Type A

Explanation:

Blood group in humans is controlled by a gene with multiple alleles. The alleles iA and iB are co-dominant over one another but dominant over allele i. In the blood type:

iAiA or iAi - type A

iBiB or iBi - type B

iAiB - type AB

ii - type O

According to this question, a man and a woman have a child together. The mother's blood type is type O (ii) and the child's blood type is type A (iAi). This means that the father's blood type must be a type A with genotype "iAiA or iAi".

In at least 200 words explain how DNA replicates

Answers

Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

~i hope this helps :)

Answer:

QUESTION:

ANSWER:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, like the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains

Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a primer

After the primer is in place on a single, unwound polynucleotide strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed nitrogenous bases. In this way, the polymerase assembles a new DNA strand on top of the existing one

A K-selected species will exhibit which of
the following characteristics?
A. wildly fluctuating population size
B. generalized niche
C. early reproductive age
D. low population growth rate

Answers

Answer:

it's D

Explanation:

This is because K-selected species produce fewer offspring in their life time compared to R-selected species therefore their growth rate is lower.

The option or characteristic that will be exhibited by K-selected species is that it has a low population growth rate. Thus, the correct option for this question is D.

What is a K-selected species?

A K-selected species may be defined as a more or less stable population adapted to exist at or near the carrying capacity. These types of species have specialized niches along with a logistic growth model.

The reproductive rate of these species is low as compared to r-selected species. Reproductive age is late. They have a fairly strong competitive ability due to which they show very less fluctuation in population size. Examples of these species may include canopy trees, large mammals, large turtles, some parrots, etc.

Therefore, the option or characteristic that will be exhibited by K-selected species is that it has a low population growth rate. Thus, the correct option for this question is D.

What is Habitat?

An area or place where an organism or a collection of organisms naturally lives and thrives is known as a habitat. It includes all the physical, biological and environmental elements necessary for growth and reproduction in a given place. A habitat can be any form of ecosystem, including a forest, desert, ocean, swamp, or dryland.

Temperature, precipitation, soil, vegetation, and other elements that are specific to each ecosystem affect what types of organisms can survive there. Other important elements of a habitat are access to food, water and shelter. Habitat theory is important to ecology and conservation biology.
