Fill in the blank.

In RNA, the nucleotide is used in place of thymine in DNA.
In eukaryotes, mRNA is transcribed in the and then transported to the cytoplasm for translation.
tRNA molecules physically link the mRNA message and the it encodes for.
The ribosome is made of proteins and .
Respond to the following based on your reading.

How are DNA and RNA similar in structure? How are they different in structure?
What are the three main RNA subtypes involved in protein synthesis? What do they do?
What is a retrovirus, and how does it work? Name an example of a retrovirus.

Uracil, nucleus, amino acid,  RNA

Explanation:

There are four nucleotide bases present in DNA and RNA, three of them ar esame in both that includes Adenine, Guanine and Cytocine but one base is different that includes Thymine in DNA and Uracil in RNA.

In eukaryotes, RNA is transcribed in the nucleus which is transported to the cytoplasm and further translated by the ribososm.

The physical link between tRNA molceules and mRNA , if it is carrying an amino acid. The tRNA molecules matches the amino acids to Codons in mRNA and link with hydrogen bonds.

The ribososme is made of RNA and proteins.

Hence, the sequential order of blanks will be filled with Uracil, nucleus, amino acid,  RNA.

DNA are RNA are two important components of living body. they have some similiarities and differences as well. They differ in their structure as DNA has double stranded or double helical structure while RNA is single stranded. similarities in the structure of DNA nd RNA is that they both have phosphorus backbone attached with four nitrogenous bases each.

There are three major types of RNA including messenger RNA (mRNA), ribosomal RNA (rRNA) nad transfer RNA (tRNA) functions for serving as temporary copies of the information found in DNA, serve as structural components of ribosomes (protein-making structures) and tranfer amino acids to the ribosome respectively.

Retroviruses are type of virus that carry reverse transcriptase to translate its genetic information into DNA. it inserts a copy of its genome into the host cell DNA and change the genome of that cell. example of retrovirus is human immunodeficiency virus (HIV) that causes acquired immunodeficiency syndrome (AIDS) in humans.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
